Abstract

Avaya commissioned The Tolly Group to measure the Layer 2 switching performance and resiliency of the company’s stackable Ethernet Routing Switch 4500 series switches.

Tolly Group engineers measured the Layer 2, zero-loss throughput and standard deviation (Jitter) for an eight-unit stack. In addition, they reported the stackable switching capacity, or the total switching throughput “external” to users and “internal” between switch stack elements. Engineers also examined stack resiliency.

Testing was conducted in May 2007.
