Matching a switch's performance in the network with the role it will play will go a long way toward optimizing your network's performance and containing costs. For our purposes, the most relevant switch performance metrics include call processing (calls set up and calls tom down per second), blocking versus nonblocking operation, the latency through a switch at peak load, and the switch's queuing strategy. Additionally, since LAN Emulation (LANE) gobbles up virtual circuits (VCs) like a kid in a candy store, the number of concurrent VCs that a switch can maintain on a per-iterface...
