Traffic Management Benchmarking
Abstract
This framework describes a practical methodology for benchmarking the
traffic management capabilities of networking devices (i.e.,
policing, shaping, etc.). The goals are to provide a repeatable test
method that objectively compares performance of the device's traffic
management capabilities and to specify the means to benchmark traffic
management with representative application traffic.
