Title: Nortel Ethernet Routing Switch 5000 Series, Competitive Performance Evaluation versus Cisco Catalyst 3750G and HP ProCurve 3400cl

Publication date:   02 February 2006
Document number:    206106

Abstract:

Nortel commissioned The Tolly Group to evaluate the Layer 2 switching performance, resiliency and ease of use delivered by the company’s stackable Ethernet Routing Switch 5000 series of switches. The Nortel Ethernet Routing Switch 5000 series of stackable switches tested include 24- and 48-port versions of 5510, 5520 and 5530 models.

Engineers measured the performance and resiliency characteristics of the Ethernet Routing Switch 5000 series switches against Cisco Systems, Inc. Catalyst 3750G switches and Hewlett-Packard Co. ProCurve 3400cl switches.

Tolly Group engineers measured the frame forwarding rate, latency and standard deviation of latency (jitter) characteristics of an eight-switch stack of Nortel switches against similarly configured stacks of Cisco Catalyst 3750G and HP ProCurve 3400cl switches. The engineers also examined the resiliency of an eight-switch stack by examining the impact of a single unit failure in a VLAN on the frame forwarding rate in a different VLAN in the stack. Engineers also measured the amount of usable Layer 2, zero-loss throughput and latency as experienced by users in a standalone switch. Finally, engineers measured the failover times of the Rapid Spanning Tree Protocol (RSTP) and Nortel’s Split Multi-Link Trunking (SMLT) technologies.
