Speedy Switches To Debut At ComNet (01/25/98; 11:19 a.m. EST) By Jeff Caruso, InternetWeek Speed and richer functionality will be the order of the day among Ethernet switch vendors at the ComNet '98 show in Washington, D.C. Foundry Networks will unveil a Gigabit Ethernet switch that can move 100 million packets per second for up to 64 separate Gigabit Ethernet connections. The BigIron switches route and use Layer 4 information for prioritizing traffic. Though no standard is in the works, the switch is even ready for 10-Gbps links, a big step up from today's 1-Gbps links, said Bobby Johnson, president of Foundry. The company has been experimenting with several different techniques to run at that speed, gaining confidence that it can be done, he said. "There was only a two-year window between Fast Ethernet and Gigabit Ethernet. It will probably be the same between Gigabit Ethernet and 10-gigabit," Johnson said. Do users need that level of capacity? "As far as the 10-gigabit, no, but we need the density" of Fast Ethernet connections that the BigIron can provide, said Larry Leonhardt, manager of information technology at JDA Software Group and a user examining Gigabit Ethernet's potential. The eight-slot version of the switch can hold up to 152 10/100-Mbps Ethernet ports. The BigIron looks at Layer 4 data to balance loads among servers, using several approaches. Johnson wouldn't disclose details until the company brings the capability to its existing product line in the next couple of months. Alteon Networks will unveil a LAN switch that integrates server load balancing and Web cache redirection. The ACEdirector 1 can distribute application sessions to the servers attached to it, based on which is most available at the time. With Web cache redirection, the box can intercept HTTP requests intended for remote hosts and can send the requests to locally attached cache servers. This way, Web access is accelerated and clients don't have to be configured to point to a proxy server, said Selina Lo, vice president of marketing at Alteon. Known for its Gigabit Ethernet switches and network interface cards, Alteon decided to apply the same switching technology to a Fast Ethernet-only switch. Bay Networks this week will debut a new routing switch. Its Accelar 1150 has four Gigabit Ethernet ports and two slots for optional modules, including a four-port Fast Ethernet module, an eight-port 10/100-Mbps module and Gigabit Ethernet modules. It routes IP traffic at seven million packets per second, the company said.
