THE KNOCKOUT SWITCH UNDER NONUNIFORM TRAFFIC

Abstract

The Knockout Switch [14] is a nonblocking, high-performance switch suitable for broadband packet switching. It allows packet losses, but the probability of a packet loss can be kept extremely small in a cost-effective way, The performance of the Knockout Switch was analyzed under uniform traffic [14], In this paper, we present a new, more general analytic model of the Knockout Switch, which enables us to evaluate the Knockout Switch under nonuniform traffic, The new model also incorporates the effects of a concentrator and a shared buffer on the packet loss probability. Numeric results for nonuniform traffic patterns of interest are presented.
