Nortel Builds Greater Resiliency Into Switches
New switches designed to help enterprises deploy secure multimedia apps at the edge of their networks.The growth of real-time, collaborative enterprise applications, such as instant messaging and IP telephony, is spurring Nortel Networks Inc. to build greater redundancy and resilience into its switches. Tuesday, Nortel will announce two new switches designed to help enterprises deploy secure multimedia applications at the edge of their networks. Real-time collaborative applications operate on distributed architecture with little central management, but typically the corporate local area network was designed to handle client server applications. The unpredictable nature of traffic from collaborative applications demands a more flexible LAN environment from Nortels perspective. The BayStack 5000 series of switches, growing out of Nortels BayStack 470 line, improves stacking performance for collaborative applications, Diane Schmidt, director of product marketing at Nortels Internet Switching Business, said. The switches, which provide Ethernet and Gigabit connectivity, incorporate simultaneous bi-directional traffic flow technology to improve the resiliency of the stack, she said, adding that they also seek the fastest path to users, making collaborative applications quicker.
"We feel this is a breakthrough platform for stackable switches," Schmidt said, adding that the new line supports Split Multi Link Trunking for rapid network recovery, and Flexible Advanced Stacking Technology to reroute traffic around a unit within a stack that is not working properly.
