Abstract

Packet switching networks with flow controlled virtual channels are modeled by closed multi-chain queueing networks. The tree convolution algorithm for an exact analysis of such models is discussed. The algorithm is very efficient when routing chains have sparseness and locality properties that are typical of communication network models. The accuracy of an approximate model of equivalent open chains was investigated. An optimal routing criterion for adding a virtual channel (with a window size of one) to an existing network is explored.
