Abstract

Multistage interconnection networks (Banyan networks) are frequently proposed as connections in multiprocessor systems, in ATM switches, or in Gigabit Ethernet switches. There exist several analytical models for evaluating the performance of such networks. Analytical models are much faster for this purpose than simulation. On the other hand, the development of an analytical model is very time-consuming. In this paper, we present a method for the automatic and fast generation of an analytical network model. The generated analysis handles networks of arbitrary size, arbitrary switching element sizes, arbitrary buffer lengths in each network stage, an arbitrary (but uniform) traffic pattern, and an arbitrarily chosen network load. The arbitrary traffic patterns include multicast traffic, which has not been considered by former models.
