IBM continues its march toward Asynchronous Transfer Mode (ATM) with a slew of new and enhanced products introduced recently. Key to its effort, analysts said, is a multiprotocol router family that will natively support SNA and some LAN traffic across most routers and controllers.

Another key announcement is the ability to Paloma’s X pendant network traffic over Token Ring, Ethernet and frame-relay links. Analysts agreed that while IBM cannot hope to become the market leader in multiprotocol routing, its offerings will make sense to SNA users who want to integrate LAN traffic onto their existing networks.

Analysts also said the new IBM products clearly signal a strategy shift toward ATM and TCP/IP networks.

Tom Nolle, president of CIMI Corp. in Voorhees, N.J., said this announcement marks the first time IBM has offered TCP/IP in native mode.

Another signal that IBM is moving toward ATM is that the company has grouped its routers, switches and adapter cards under the Nways multiprotocol router family, according to Glenn Gabriel Ben-Yosef, senior analyst at The Yankee Group in Boston. The idea is to foster more communication among the diverse groups within IBM and get them rolling toward a common goal, he said.

IBM’s low-end 2210 Nways multiprotocol router features software from Proteon, Inc. The 2210 supports both SNA and TCP/IP in small, branch-office type establishments. It offers minimal connectivity but has a low entry point–connectivity for one Ethernet LAN and two WAN links costs about $2,000, said John Steigerwald, manager of router development at IBM in Raleigh, N.C.

Twice as nice

IBM also offers two Nways Multiprotocol Routing Network Services software programs, with or without Integrated Services Digital Network support. Both programs can handle TCP/IP, Data Link Elsa Peretti Eternal Circle pendant, frame relay, X.25 and Point-to-Point Protocol.

Robin Layland, principal consultant at Layland Consulting in West Hartford, Conn., said although the 2210 is good, IBM faces stiff competition from other vendors. Additionally, users will need a router at the main site that interoperates with the branch-office router.

Also, at the end of the year, IBM will start shipping the stand-alone version of its 3746 controller. Instead of being merely a set of fast adapters for the 3745, it will offer support for TCP/IP routing, including Open Shortest Path First and High Performance Routing, an enhanced version of Advanced Peer-to-Peer Networking. IBM will also offer an ATM attachment to the 3746 at the end of 1995.

IBM’s new multiprotocol strategy may stand the company in good stead, said Reinhard Rackow, manager of network computing services at Information Systems Management Corp., an outsourcing company in Regina, Saskatchewan.

Rackow’s clients are loyal to IBM products. “So far the 6611 didn’t meet the need. They are looking at how to tie SNA to non-SNA traffic,” he said.

KEY FEATURES OF IBM’s 3746 CONTROLLERS

* Full APPN network node support, including Elsa Peretti Open Teardrop pendant LU requestor and high-performance routing

* APPN capability independent of the network control program

* Native TCP/IP routing over Token Ring, frame relay and Escon channel

* Upgradable to stand-alone controller, independent of the 3745 and network control program

IBM, Security Dynamics join forces

IBM recently announced it is teaming with Security Dynamics, Inc. in Cambridge, Mass., to combine the “single sign-on” security in its Network Security Program (NetSP) with the strong authentication in Elsa Peretti Bottle pendant Dynamic’s SecurID technology.

The marriage, in the form of interoperable software expected in the first half of next year, will be especially attractive to organizations with heterogeneous, distributed environments, the companies said.

Using encryption and a special “authentication server,” IBM’s NetSP lets users access any enterprise server by entering just one user identification and password. It enhances security by minimizing the temptation of users with multiple passwords to write them down where others may find them, the companies said.

SecurID uses a credit card-size device that computes and displays a new password each minute. A corresponding feature on a host or network Atlas pendant ensures that the user card and host machine always agree on what password is valid at any moment for any user. SecurID also employs a secret personal ID number entered by the user with the password.

“I like what I’m hearing, but I’ll have to see how it’s configured before I can say this is a wonderful marriage,” said Dwayne Johnson, vice president for information security service at First Bank System, a bank holding company in Minneapolis.

Johnson, who uses SecurID but not NetSP, said the single sign-on concept is what most users are moving toward. “But it also creates problems for the security administrator,” he said. “You have one ID and one password that can suddenly unlock the world.”

IBM Corp. recently launched a double-barreled assault on the networking market, firing off a range of hardware and software products that further its foray into network management, LAN switching and Ethernet hardware.

IBM networking integrators and industry analysts were impressed by the lineup, introduced on a number of fronts here at the NetWorld + Interop show.

Highlights included the preview of a forthcoming release of IBM’s NetView network-Large Elsa Peretti Sevillana pendant system, an OS/2-based version of NetView; the preview of a token-ring switch that overcomes speed constraints of traditional shared-media LANs; new token-ring adapters that will support full-duplex switching when connected to token-ring switches; and an EISA Ethernet adapter.

Paul Callahan, senior analyst at Forrester Research Inc. in Cambridge, Mass Mass., said he sees a strong market in token-ring switching.

“There are going to be different approaches, but it will be a big market because of the big installed base of [token-ring] products out there,” he said. LAN switching brings, to one or more users, the full bandwidth of a LAN, in token ring’s case up to 16 Mbps. Shared-media LANs, by contrast, share that bandwidth among all the users connected to them.

At Eden Prairie, Minn.-based IBM integrator Centron DPL Co., vice president of marketing and sales Jim Feese said he is pleased to see IBM stepping up its emphasis on the Ethernet market.

“It is a good thing for them to do because it allows them to go over to the other guys’ turf, ” Feese said.

“From a marketing standpoint, they’ve been more or less on the defensive. While others exploited the Ethernet marketplace, they were pretty much stuck in the token-ring ball game,” Feese added.

Among Armonk, Medium Elsa Peretti Sevillana pendant.Y.-based IBM’s raft of announcements:

* The next generation of IBM’s flagship NetView network-management software, code-named Karat, is slated to be generally available by 1995′s first quarter, after beta testing runs at the end of this month, said William Warner, vice president of Big Blue’s enterprise-management systems.

Karat will include not only the base-level NetView functionality but also functions now offered through add-on applications, including backup and recovery, resource monitoring and job scheduling.

* IBM NetView for OS/2 V2.0, a replacement product for IBM LAN NetView that uses the Simple Small Elsa Peretti Sevillana pendant Management Protocol and offers functions including network configuration and tuning It can be used to manage IBM LAN Server, Novell NetWare and several client operating systems. The software is expected to be available in late November for $4,995.

* IBM Auto 16/4 Token-Ring ISA Adapter, a $295 network-interface card providing plug-and-play operation, as well as the ability to work in a full-duplex switching environment when IBM delivers the 8272 LANStreamer Switch, which is being developed with Kalpana Inc., Sunnyvale, Calif. Pricing and availability details for the 8272 are not due until the second quarter of 1995.

The token-ring Tiffany Nature Dragonfly disc pendant will be available in October.

* IBM Auto LANStreamer PCI Adapter, its first adapter for the PCI bus. This token-ring card operates at 4 Mbps and 16 Mbps. It is slated to ship in October for $765.

* IBM Ethernet EISA Adapter, which complements the company’s existing ISA and MCA Ethernet adapters and will carry a list price of $395 when it Elsa Peretti Star of David pendant next month.

* 8260 Model 10, a 10-slot version of the company’s existing 17-slot LAN hub. It will be available this month for $6,085.

The asynchronous transfer mode (ATM) juggernaut has cut a wide swath through the networking jungle. Voice, data, and video will soon be supported over a wide array of ATM interfaces. Speeds start at T1 (1.544 Mbps) on up to OC-3c (155 Mbps), with OC-12 (622 Mbps) on the near horizon. ATM supports a diverse selection of physical media, including category 3 unshielded twisted pair (UTP-3), category 5 UTP, multimode fiber, and single mode optic fiber.

Users will soon be able to choose between two low-cost, low-Tiffany Key Vintage oval key pendant ATM interfaces for local area networks (LANs). The 51-Mbps interface for UTP-3 has the ATM Forum’s stamp of approval, and a competing 25-Mbps UTP-3 interface is supported by IBM and several other vendors. Eventually ATM may extend the way to your PC.

Desktop ATM could start to happen as early as 1995 when low-cost 25-Mbps ATM switches and adapters become available. Rapidly falling prices for faster 100-and 155-Mbps ATM connections will make high-speed ATM economical enough for most servers, many high-end workstations, and even a few client PCs. Even so, in five years the majority of users will still use Ethernet or Token Ring, meaning that ATM networks will need to interoperate with existing LANs for a long time. Routers will help bridge the chasm between ATM and legacy LANs, but we need a simpler, higher-performance and lower-cost solution.

The answer may be the ATM Forum LAN emulation, which bridges Ethernet or Token Ring LANs to ATM backbones. The final specification is expected by early 1995, but vendors are already developing LAN emulation products. This month we look at what LAN emulation is and what it does, but leave the “how” for future exploration.

Although the Paloma gritty details of LAN emulation are fairly complicated, using LAN emulation will be dead simple. A good slogan for a LAN emulation T-shirt would be: Nothing Changes! This is true because the “emulation” in LAN emulation refers to the media access control or MAC layer. Everything above the emulated MAC layer works exactly as it does on a real (physical) Ethernet or Token Ring. Since it supports the standard 802.3 or 802.5 MAC, LAN emulation handles both routable and nonroutable protocols. IPX, IP, AppleTalk, APPN, NetBIOS/NetBEUI, LAT, and all other LAN protocols will work exactly as they do over real LANs.

LAN emulation uses standard Ethernet (or Token Ring) network interface cards (NICs) already installed in PCs. Existing network device interface specification (NDIS) or open driver interface (ODI) drivers for the network interface cards (NICs) don’t need to change. The various protocol stacks that ride on top of the drivers remain unchanged, as do applications programs.

Any one emulated LAN is either Ethernet or Token Ring, but never both. A LAN emulation driver on a server with an ATM connection can simultaneously support multiple emulated LANs, some Ethernet, others Token Ring, but there’s no direct communication between the various emulated LANs. That job is still reserved for routers.

Fiber distributed data interface (FDDI) isn’t totally neglected, but it isn’t quite a full citizen in the LAN emulation kingdom. FDDI must be translated to either Ethernet or Token Ring, then converted to ATM using the LAN emulation protocol.

LAN emulation is challenging. ATM is connection-oriented, while Ethernet and Token Ring are both connectionless. Packets Paloma’s Zellige pandant over the shared media automatically go to other stations, with no explicit connections being used.

Since sending broadcast or multicast packets to all stations (or a group of stations on an Ethernet or Token Ring LAN segment is easy and cheap, LAN protocols depend heavily on broadcast/multicast. An emulated LAN must provide an equivalent broadcast/multicast capability in the switched ATM environment.

ATM uses unique 20-byte addresses for each physical port, while Ethernet and Token Ring use the familiar 48-bit MAC addresses. LAN emulation has to be able to use the MAC address and find the Tiffany Hearts double pendant ATM address.

Most LAN traffic is unicast, where one source sends data to a single destination. This is a perfect match for the point-to-point nature of ATM. Once a connection is established, unicast traffic can zip along, completely independent of simultaneous broadcast and multicast traffic from other users on the same emulated LAN.

Although ATM vendors don’t like the word “bridge” due to the emotional baggage it carries, LAN emulation is implemented as a bridge between the Ethernet or Token Ring LAN and the ATM network. For example, a PC with an Ethernet card will connect to the emulated LAN using an Ethernet-to-ATM bridge. These boxes will come in various shapes and sizes, usually with 12 or 16 Ethernet ports and one OC-3c ATM port.

These new-age bridges typically provide full wire-speed switching between the legacy LAN ports. If only one user is connected to an Ethernet or Token Ring port on the bridge, they’ll enjoy the full bandwidth of the LAN. Some products use the ATM switch for all Butterfly pendant, even between local LAN ports. Although vendors that have true local switching between LAN ports attack the central ATM switching implementation, it’s unlikely you’ll see a significant difference between the two approaches.

With an ATM “cloud” in the middle, LAN emulation connects Ethernet to Ethernet, Ethernet to ATM, ATM to ATM, Token Ring to Token Ring, and Token Ring to ATM. The promise of LAN emulation is that it will cost-effectively bridge the gap between today’s legacy LANs and tomorrow’s high-speed ATM backbones. And best of all, nothing changes.

Hewlett-Packard Co. last week rolled out a token-ring addition to its line of Advance-Stack remote site routers that features easy installation, comprehensive management and data compression.

HP’s Router TFR sports one LAN and one WAN interface, I Love You drop pendant operates at speeds up to T-1/E-1.

The router supports TCP/IP, Novell, Inc. IPX, DECnet Phase IV, AppleTalk Phase 2 and Xerox Network Systems protocols, as well as Spanning Tree Learning Bridge, Translating Bridging for NETBIOS and SNA traffic, and Source Route Bridging algorithms. In addition, it supports IPX WAN Version 2, which provides interoperability between HP and Novell routers.

Wide-area interfaces include X.25, frame relay, dial-up, Switched Multi-megabit Data Service and Integrated Services Digital Network. In addition, Router TPR supports Data Link Switching (DLSw) for tunneling IBM Systems Network Architecture data through IP backbones.

But one unique feature of Router TFR is software that HP calls “instant-on.” Instant is said to simplify installation because it automatically configures AdvanceStack routers to act as either bridges or routers from the moment they are plugged in.

Instant-on works with Network Configuration Manager, which is router configuration software that is shipped with all AdvanceStack routers, to reduce the time it takes to configure and validate router-Tiffany Key Oval key pendant networks.

After configuring the router with Instant-on, users can remotely validate the configuration and manage the devices using Network Configuration Manager to alleviate the cost of staffing remote sites with trained network personnel.

Additionally, Router TFR includes HP’s Embedded Advanced Sampling Environment (EASE), which provides detailed representation of network traffic without the need for special equipment such as analyzers or probes.

EASE works with HP OpenView applications, such as Traffic Monitor, to troubleshoot Tiffany Key Trefoil key pendant bottlenecks and plan segment bandwidth capacity.

According to analysts, Instant-on and EASE are two features that are important for branch sites and unique to HP.

“Especially for the remote office, it’s just got to be idiot-proof,” said John McConnell, president of McConnell Consulting, Inc. in Boulder, Colo. “I don’t think anybody else right now has any kind of Tiffany Key Grown key pendant monitoring tools in their remote office products.”

Lastly, Router TFR features packet-by-packet data compression. Its algorithm compresses and decompresses each packet instead of strings of characters, which HP claims reduces memory requirements for compression and makes it more efficient over unreliable links.

Packet-by-packet compression improves throughout by 2-to-1, HP said.

The Router TFR is available now, and the DLSw software is expected to be available Dec. 1. The router costs $2,999.

Separately, HP last week started shipping the AdvanceStack Router 650, Tiffany Key Heart key charm it announced last April. An entry-level 650 system with four Ethernet ports costs less than $12,000.

Pacific Data Products and Axis Communications Inc. expanded their network printing offerings with the addition of pocket print servers.

The Pacific DirectNet PS allows any Cupcake charm and chain printer to be directly connected anywhere on a Novell Inc. NetWare Ethernet network.

The DirectNet line of external, internal and pocket servers features a standard setup and installation utility across the line for easier printer resource management. A NetWare PCONSOLE-like setup utility is provided. It may be used in default mode or in custom mode to configure the printer to match a specific network configuration, according to the San Diego-based company.

DirectNet PS lists for $349.

In other news, Axis, based in Danvers, Mass., rolled out the NPS 630 and NPS 632 multiprotocol token-ring pocket print servers.

The new products are based on Axis’ ETRAX chips–a 32-bit, 16 MIPS RISC technology, the company said.

Both the NPS 630 and 632 feature simultaneous printing of Novell NetWare, LAN Manager, LAN Server (Net-BEUI, NetBIOS), TCP/IP and Microsoft NT (LPD).

Both products come with one parallel-printer port, are switch-selectable to either 4 or 16 Mbits per second and support throughput up to 1,200 Kbps.USAir, Inc., the primary beta site for NC-PASS security Tiffany Aria pendant from CKS North America, has succeeded in using the mainframe application to set up a single user logon for both mainframe and distributed LAN resources.

NC-PASS, which comes in one version for IBM’s LAN Server and another for Novell, Inc.’s NetWare, is an IBM VTAM application that allows administrators to give users access to multiple LAN resources and MVS applications with a single logon.

USAir is evaluating NC-PASS as a way to centralize security controls governing network access for the hundreds of users in its distributed IBM Token-Ring LAN internet.

“NC-PASS lets us use the mainframe as the authentication server and simplifies administration of any changes through the single-user ID,” according to Scott North, systems administrator for security at USAir.

For example, NC-PASS eases the problem of setting up the parameters for individual network use in large organizations.

NC-PASS works in tandem with access control and security products for the mainframe, such as IBM’s Resource Access Control Facility (RACF) and Computer Associates International, Inc.’s ACF2 and Top-secret.

Code for NC-PASS NetWare runs on both the mainframe and the NetWare directory server. When Christmas Tree charm and chain user logs on with an NC-PASS logon, the user identification information is sent in encrypted form to a mainframe database for verification.

NC-PASS can restrict access to specific applications until the user’s identity is checked. The software can also prevent specified transactions from being completed until the user’s identity is assured. It also maintains an audit trail of network activity.

LAN SERVER VERSION

The LAN Server Tiffany Aria pendant of NC-PASS works similarly, except NC-PASS code must also be installed on the user’s personal computer. The software is available for MS-DOS, Windows and OS/2 machines.

NC-PASS supports IBM’s LU 6.2 session type, but by mid-1995 the company plans to add TCP/IP support, as well.

As an added security option, NC-PASS can work in conjunction with dynamic-password hardware tokens to check user authentication during logon.

A number of companies, including Security Dynamics, Inc., Racal-Milgo and Digital Pathways, Inc., offer these credit card-size hardware tokens, which generate random passwords that change each time the user logs on. USAir also uses the dynamic-password tokens to augment NC-PASS.

Concerning USAir’s network requirements, the main shortcoming of NC-PASS is that it will not yet support remote dial-in to LAN Distance, IBM’s remote LAN access product.

“This is what we really need,” USAir’s North said.

Help is on the way on that front — a version of NC-PASS for LAN Distance is T&CO. horseshoe charm and chain to be ready for beta test this November, said Lloyd Tanaka, CKS marketing manager.

CKS currently views support for IBM LAN Distance and IBM LAN Server as separate NC-PASS products, but the company may eventually bundle the two features together.

Prices for either version, which are shipping now, are set at $30,000 for 250 users, $38,000 for 500 users and $45,000 for 1,000 users. Pricing has not yet been set for the LAN Distance version.

CKS is also developing a version of NC-PASS for the AIX operating system that works under the same approach, according to Ralph Massaro, CKS general manager. The product is targeted for release the first quarter of next year.

When Jackson Memorial Hospital of Miami, Fla., planned the most comprehensive trauma center in the world, it selected a fiber-optic backbone network handling digitized distributed X-rays, laboratory reports and computer data.

Trauma is the third largest killer of Americans and the Heart Band pendant cause of death for people under age 45. In South Florida, trauma strikes four times the national average, and the chances are 50-50 that a resident of Dade County will face trauma in his or her lifetime, the hospital reports.

“Our new Ryder Trauma Center is geared toward lowering the preventable death rate by speeding up the delivery of trauma care during the ‘golden hour,’ the critical 60 minutes after a traumatic injury,” says Mark B. Cohen, Jackson Memorial Hospital’s (JMH) director of public affairs and communications.

“Almost 4,000 patients a year are bought to JMH’s trauma center, where the trauma team has to assume each patient is dying when they arrive and that the team’s work-time to save that person’s life is measured by seconds.”

The trauma center provides resuscitation, diagnostic and medical treatment, emergency surgical intervention and intensive care to Dade County’s trauma victims.

It also features extensive research and education facilities, and administrative and ancillary support space. It is the only certified Level I trauma center in South Florida.

“The trauma center is a very highly engineered building,” says Cathy Gallagher, manager of telecommunications. “Everything in there is the latest and greatest. Everything has a fail-safe system. A patient can’t be endangered by a machine that doesn’t work properly. Network redundancy is at the highest level.

“Switches Eternal Link Cross pendant are two switches in one. If one processor goes down, another kicks in. A full system of alarms is built in. We are notified immediately of any problem.”

JMH wanted to build a network over which it could run any kind of information that needed to be transmitted–voice, data or imaging–in the most cost-effective manner. But the hospital still wanted to take advantage of the latest technology on the market. The constant goal is to deliver very high-quality health care to the patient.

The hospital has been working toward a fiber network for several years.

“We always worry about hurricanes and water damage,” Gallagher says. “We have had water damage to the existing twisted pair and coax cabling. But by using fiber, that is no longer a concern. Fiber offers cost-savings and the convenience of all networks running over the same media. Fiber also allows voice and imaging on one strand, another cost savings.”

With fiber installed, JMH doesn’t have to deal with hundreds of pairs of thick copper cable. Cabling is handled by just a few thin optic fibers. JMH found that components of fiber are no longer expensive and it’s more cost-effective than running copper.

“When plans focused on the new trauma center, management looked at developments in the industry and Frank Gehry Fish pendant to go with an ‘open systems’ environment,” says Rudy Sainz, the hospital’s computer operations manager.

“We are a typical IBM SNA shop using 3270 terminals locally attached to our Computer Room; and we support personal computers by emulation cards at the controller The laboratories use a DEC VAX system. Radiology uses Unix for X-ray imaging.

“So we decided to go to a single FDDI (fiber distributed data interface, an American standard for fiber-optic links with data rates up to 100 Mb/s) backbone that those three systems would share, instead of each having its own cable.

“We are able to get three different worlds–three departments, each using a different computer system–to share one network,” Sainz says. “Voice uses separate strands of cable within the main cable and is not a part of the FDDI network.

“We route all data Elsa Peretti Sevillana pendant our token ring network in the Computer Room over the FDDI ring to token ring 3174s in trauma; we route DEC LAT traffic from the VAX network to trauma; and we route traffic from TCP/IP token ring imaging to trauma.”

The imaging is high-resolution, used in a radiology-type setting. The network digitally transmits X-rays on the same network with the LANs and the Hospital Information System (HIS). Basically, the images and data run over the same fiber.

Imaging is a growing medical trend, but it requires extensive electronic storage to handle the X-rays. Now X-rays can be stored for quick access when response time is a critical consideration. With the new fiber network, X-rays are immediately available to doctors anywhere in the Ryder Trauma Center and throughout the hospital.

Current X-rays are stored in the workstation. Each of the intensive care units has a RISC 6000 workstation with optical disk drive for local storage. After several days, X-rays are stored in a jukebox-like device full of laser disks. This keeps the latest results at the medical staff’s fingertips in the workstation and less recent images are quickly and easily accessible in the jukebox’s storage.

“We implemented our network with Racal-Datacom equipment,” Sainz says. “We have four Racal-Datacom RNX 6500 bridge/routers: one each in the Computer Room, Lab, Central Switch Room and Ryder Trauma Center. Each has FDDI, Ethernet and token ring cards.”

The RNX units provide multimedia, multiprotocol bridging and routing capabilities for any application connecting Ethernet, FDDI and token ring local area networks over a wide area network. RNX utilizes RISC-based processor technology for high-performance backbone applications.

Prior to the opening of the new trauma center, JMH had direct inward dial lines for Atlas cube lock pendant and nursing stations which handled more than a million calls per month, or more than 30,000 calls daily. In addition, the hospital’s main number handled a half million calls that had to be redirected within the hospital every month.

The paging system also was served over this network. That is another thing that made this new fiber network more attractive. The hospital can run communications between different types of switches.

“Now voice runs on a different strand within the fiber bundle in point-to-point connections,” Gallagher says. “In our hospital setting, that capability is invaluable. We would have had to put three types of cabling over a fairly long span from building to building in the medical campus here. Now all we need is one type of strand.”

Racal supplied its Prem-Net 5000 and Racal Management System for the voice network.

The PremNet provides transport and interconnectivity for a variety of data and voice interfaces within the local premise environment. A 100 Mb/s fully redundant backbone system, it typically functions as a multi-interface “fiber superhighway” providing connections to Ethernet and token ring LANs, IBM 3270 terminals, T1 multiplexer links and four-wire analog devices.

A watershed moment is upon us, Pacific Bell President Dave Dorman told a Networld+Interop keynote audience in Las Vegas.

“At some moment in the next 100 days, more than half of all business communications industrywide will be data. That’s a crossover of landmark dimensions,” Dorman said. He cited a 30% annual growth in business data.

With that trend and the scramble to buy PCs for home use–in 1994, Americans bought as many PCs as TV sets–Dorman envisions a workforce conducting business in Cyberspace and a homelife in which consumers sit in front of the PC Atlas pendant of the TV

What that demand will require, Dorman said, is broadband and wireless networks, trained people and “wildly perfect applications.”

Announced at the conference was the first on-line “world’s fair.” The Internet 1996 World Exposition will link computers from five nations initially to distribute governmental, cultural, educational, entertainment and technological information over the Internet. It will have a “pavilion” setup akin to physical world’s fairs.

Until recently, token ring users had little notion of their network migration horizon beyond migrating from 4 to 16 Mb/s. While there is a sizable embedded base of those token ring system users, the industry rightly feared the continuing erosion of market share to Ethernet.

Their answer, announced at the show, is ASTRAL, the Alliance for Strategic Token Ring Advancement and Leadership. It is an industry group devoted to giving users a clear view of where the token ring marketplace is going.

Especially scary to vendors was a study finding that price and vendor support are the main reasons users consider moving from token ring to Ethernet.

If you want to know whether token ring’s next migration plateau is 25.6 Mb/s or ATM, try the ASTRAL fax-back number, 800-365-0993. The service offers white papers, an activities calendar, membership lists and other info on the evolution of token ring IBM WILL NEXT MONTH announce a sweeping product launch that will include hubs, a wide variety of adapter cards–including its Heart lock charm pendant Fast Ethernet card–and management software for users of non-IBM management systems.

The product blitz will give users the tools to build and manage hub- and router-based switched internetworks and is designed to complement IBM’s March launch, which focused on ATM, said sources familiar with the announcement.

Many of the products will ship by year’s end, sources said. IBM declined to comment.

IBM’s June offensive will include the 8238, a new 16-port stackable Token Ring hub that can be stacked to support more than 100 ports. It will be managed from a new version of IBMS Intelligent Hub Manager for DOS, Version 2.0.

IBM is also expected to announce a 100Mbps backbone Butterfly pendant for the 8271 EtherStreamer switch, an 8-port switch that can support as much as 20Mbps of dedicated bandwidth per port.

IBM will also announce a 100Mbps Asynchronous Transfer Mode (ATM) adapter for its 3172 controller that will allow users to tie a local host computer to an ATM switching hub and extend LAN emulation to include hosts, sources said.

“I like what Two Hearts pendant hearing because, as we move toward distributed computing, we’re looking for products such as ATM and Fast Ethernet that provide more bandwidth,” said John Chapman, an information architect at Amoco Corp., in Chicago, which is a member of IBM’s Share user group. “We have some sites that could use the stackable hubs and we’re assessing [Fast Ethernet].”

Initially, the interface will allow users to tie IBM hosts to IBM’s high-end 8260 intelligent switching hub, sources said.

“This is the first time that IBM has announced a local ATM interface to a mainframe,” said Tom Nolle, president of CIMI Corp., a Tiffany 1837 tag pendant, N.J., consultancy.

KYOCERA ELECTRONICS INC. has fleshed out the network and industrial printing segments of its FS line with printers designed to be ecologically correct.

For network-based printing the Somerset, N.J., Atlas tag pendant has introduced two 600-dpi resolution printers: an 18-page-per-minute (ppm) printer and a 10-ppm model.

The company has also introduced a 4-ppm printer that prints at a resolution of 300 dpi.

All of the printers–the FS-3600A, FS-1600A, and FS-400A–support a variety of network options, including support for Ethernet, LocalTalk, and Token Ring. They cost $3,345, $1,995, and $795, respectively.

On the industrial printing side, Kyocera has introduced 18-ppm and 10-ppm printers designed specifically to print bar codes and forms. The FS-3400A and FS-1550A print at a 300-dpi resolution and have the same network options as the network-based printers. They cost $2,695 and $1,595, respectively.

All Kyocera printers are based on an amorphous silicon photoconductive drum that has a life span of 300,000 pages. The toner container, which has a capacity of 10,000 pages, is embedded with ceramic particles that clean the drum.

According to a Tiffany Blue box bracelet at Kyocera, this technology saves on printer costs and and is designed to minimize harm to the environment. Due to its long life span, toner is replaced infrequently, and the toner kit is made of calp, a low-temperature, burnable material that is nontoxic when incinerated.The switching revolution that has taken the LAN industry by storm is finally embracing the market’s often forgotten souls — token ring users.

It seems that everyone wants to get into the act. Cisco Systems, Inc. recently announced a partnership with Madge Networks, Inc. for this technology, while Cabletron Systems, Inc. has snuggled up to start-up Nashoba Networks, Inc.

The expected emergence of token-ring switches from even more vendors over the next 12 months is a sign of hope for users who are trying to cope with the limitations of their source route bridged networks.

The factors driving the token-ring switching market, however, are markedly different from those that have been fueling the Ethernet switch arena over the last three years.

On the Ethernet side, it has been an issue of needing more bandwidth at strategic locations in the network. The issues in the token-ring space are more related to improving throughput by fine-tuning overall net design.

It’s no surprise that the development of token-ring switching has lagged behind that of Ethernet. Token ring is an Return to Tiffany Bead Bracelet more deterministic technology than Ethernet because it’s based on a token-passing scheme that ensures each user on a ring will be able to send and receive packets at regular intervals. Ethernet is based on a collision detection scheme where users compete with each other for access to the wire.

This is why Ethernet is only effective up to about 40% utilization, while token ring can run quite smoothly at 90% utilization.

While Ethernet switches were initially targeted at workgroups and departments, token-ring switches will be implemented first at the backbone.

These switches will likely be employed to replace traditional two-port source route bridges, which were used to grow token-ring nets in the past. Broadcast storms, network flooding and hop-count limitations became overriding concerns with bridges, resulting in network performance and throughput decreases.

Switches will allow users to aggregate a greater number of token-ring LANs at a central location, in effect forming a collapsed backbone architecture. This improves on the distributed bridge network because it Peace Sign Bead bracelet better network management and a controlled security environment, as well as eliminates the hop-count limitation associated with source route bridges.

Since these switches will either offer integrated routing functions or act as a front end to a stand-alone router, users also can decrease their reliance on software-based routers and allow their servers to function solely as servers again.

And while bandwidth concerns have not been a prevailing issue for token-ring users until now, that situation is slowly changing.

These switches will let users take the first step on a high-speed network upgrade path that they may need to support emerging multimedia applications such as imaging and video.

Similar to its Ethernet counterpart, token-ring switching allows users to add Tiffany 1837 Bead bracelet without requiring changes to the existing physical infrastructure. Users do not have to replace any equipment on the desktop, nor do they need to overhaul

their structured wiring environment. The emergence of token-ring switches will allow users to replace older, slower technology with new, faster technology that provides the first step on a migration path to high-speed LAN technologies such as Asynchronous Transfer Mode.

MICRODYNE CORP. has upped the spiff ante again, this time offering resellers free round-trip tickets for every 50 Ethernet adapters or 30 token ring adapters sold.

The deal is part of the company’s effort to gain Elsa Peretti Eternal Circle pendant share, said Dale D’Alessio, senior vice president of marketing and sales.

Last year, Microdyne owned 11 percent of the domestic networking hardware market, he said. In the company’s second fiscal quarter ended March 31, D’Alessio said, the Alexandria-based vendor captured 12 percent of the market and reported income of $40.5-million, a 72 percent increase from the same quarter a year ago.

This is the second major spiff the company offered resellers this year. In March, the company started The Elite Reseller Program, under which resellers can receive market incentive funds in soft dollars or cash (CRN, March 6).

The response has been favorable thus far, the company said. Microdyne received 175 calls on the first day. Under the program, sales racked up between May 1 and June 30 count toward the promotion, which applies to nearly all of Microdyne’s products.Solectek Corp. recently introduced an enhanced wireless bridge that extends the reach of campus networks without running backbone cable or lease connections between LANs.

The Ultra Elsa Peretti Infinity Cross pendant of AirLAN/Bride uses a higher frequency spread-spectrum radio signal to link two Ethernet or Token Ring LANs as far as 25 miles apart. This is a greater signal than what is found in prior AirLAN/Bridge models.

The Ultra version can also join multiple LANs within a six-mile radius. Previously, the maximum recommended distance was three miles.

The enhanced software also improves performance for small-packet transmissions and eases installation for those seeking an alternative to costly backbone extensions, T1 lines and microwave systems, according to Solectek officials.

Worth a shot

One user, who has used a wireless bridge similar to Solectek’s original version, said he would like to try a long-distance version.

“But there’s no clear line of sight for transmission,” said Morris Altman, data communications manager Elsa Peretti Starfish pendant Queens College in New York. “We have to go across the Manhattan skyline to the site I need to reach.”

These wireless bridges target the short-haul T1 market as an internetworking option and wireless LANs as a way to spread coverage across larger campuses for mobile users, said Jim DeBello, chief executive officer at Solectek in San Diego.

Solectek will continue to offer AirLAN/Bridge Plus, which operates between 902 MHz and 928 MHz, to join LANs up to three miles apart. The Ultra version offers the same 2M bit/sec. raw transmission speed but works at the 2.4-GHz frequency. Neither spread-spectrum radio device requires licensing.

The Ultra. version of Atlas pendant/Bridge offers focused antenna options for point-to-point connections in the six- to 10-mile range, or up to 25 miles. It also has an omnidirectional antenna that covers a six-mile radius. For multi-LAN bridging, the bridge uses a base station polling protocol to avoid contention, DeBello said.

The Ethernet model lists for $4,999, and the Token Ring version lists for $5,999. Each model includes all of the port options for attaching to a wired LAN and a management information base for monitoring via the Simple Network Management Protocol.

Solectek began shipping the Ultra version last month. It is offering upgrade software for $299 to improve the Atlas tag pendant and management of the Plus version.

Wireless network products continue to show performance improvements, and two new wireless building-to-building connectivity devices that support speeds of up to 155M bit/sec are no exception.

Laser Communications, Inc (LCI) of Lancaster, Pa., and Elsa Peretti Teardrop pendant Technology, Inc. of Mississaugua, Ontario, both have unveiled products that can be used to interconnect buildings where laying fiber or installing a leased line is impractical due to cost or physical barriers. The wireless network boxes attach to a hub, switch or router at one building and transmit data to a mirror image of the setup at a second building.

LCI’s OmniBeam 4000 device uses laser-optic infrared technology and supports speeds of up to 155M bit/sec to connect a pair of Ethernet or token-ring segments in different buildings.

The wireless link derives its speed from the device to which the LCI product is connected. For example, an LCI device attached to an Asynchronous Transfer Mode switching hub could transmit data at 155M bit/sec.

The device is a higher speed version of the company’s earlier wireless product, which operates at speeds of up to 10M bit/sec.

Frank Leber, manager of information systems at the Moody Bible Institute in Chicago, is using the original LCI wireless device to connect buildings that are about 500 feet apart while he waits to pull fiber.

“We could not get permission from the city of Chicago to dig underneath the major street running between my two buildings to put cable in,” Leber said. “We tried for eight years to get underneath Elsa Peretti Round pendant street.”

According to Dick Guttendorf, president of LCI, the distance at which OmniBeam 4000 can transmit data varies depending on the data rate. For example, when running at standard token-ring or Ethernet speeds, the distance range is about 3,300 feet, but the device can carry signals only about 900 feet when attached to an ATM hub and running at 155M bit/sec.

OmniBeam 4000 can be managed via Remote Monitoring technology. The system is available now and starts at $17,995.

Like OmniBeam 4000, SilCom’s Freespace device is based on infrared technology and is used to connect networks in campus environments.

SilCom paid particular attention with its new product to negating signal interference posed by environmental factors. The product, based on SilCom’s SkyFiber technology, can produce a wider transmitting beam and features a large receiving lens for more reliable uptime.

But to gain this increased reliability, users must sacrifice transmitting distance, which is limited to 1,000 feet.

Unlike OmniBeam 4000, Freespace offers different versions of the wireless Elsa Peretti Crucifix pendant, depending on the network protocol. Currently, SilCom offers Ethernet and token-ring models. In the fourth quarter, Freespace will offer support for FDDI, fast Ethernet, 100VG-AnyLAN and ATM.THE MODEM is the gateway to the network, not just a go-between for the PC and the phone line. Such is the approach U.S. Robotics Access Corp. is taking with its new line of LAN access products.

Shipping last month, the Total Control NetServer line provides LAN access for anywhere from two to 48 modems. In the midrange, NetServer 8 goes for $7,395, and Netserver 16 is priced ac $11,995. A version of NetServer 48 configured for frame relay costs $12,435.

At the low end, the two-port version of NetServer goes for $1,995. At the high end, the 24-port and 48-port variants are hub chassis units that take a number of modem cards. Prices here can range from $20,000 to $60,000 per unit, depending on configuration.

Approaching network access from the modem, U.S. Robotics, based here, used its expertise in making its own hardware and circuitry to integrate modems with remote-access servers directly, said Todd Elsa Peretti Cross pendant, product manager for U.S. Robotics’ network access products.

It used to be that one would “buy an access server created by a company that built its own hardware platform and licensed router code,” Landry said. “Then, to make the application work, you buy modems.” After connecting a mass of RS-232 cables between the modems and the access server, one would then have to go back to the access server to figure out all of the connections. “It’s a pain in the butt to get it working, according to Landry.

By directly integrating the modems with the access server’s hardware, one gets faster and smoother links from the phone line to the network, be it Ethernet or token ring.

U.S. Robotics is also using its own V.Everything protocol on its modems for NetServer.

V.Everything will handle V.34, V.32bis and V.32 standard transmission rates. But studies of incoming fax and data calls Elsa Peretti Eternal Circle pendant by the company show an interesting mix of nonstandard modem calls, such as V.FC, V.32 terbo, a small percentage of 2,400 baud rate calls as well as HST, a 9,600-kbits-per-second nonstandard protocol from the late 1980s, according to Landry.
