GENERAL DESCRIPTION

The GigaStream? chip set is a high performance synchronous switch fabric consisting of two integrated circuits: the GigaStream Queuing Engine (VSC872) and the GigaStream Crossbar Switch (VSC882). Targeted at the access, edge, and metropolitan markets, GigaStream enables networking equipment manufacturers to build routing and switching systems capable of providing a maximum of 80Gb/s of aggregate user bandwidth with up to 320Gb/s of highly available backplane bandwidth. GigaStream provides support for sophisticated Quality of Service (QoS) algorithms, distinct handling for both Unicast and Multi/Broadcast traffic, as well as multi-service support for IP, ATM, and Ethernet
