On the Performance of Cubic Networks under Correlated Traffic Pattern

The efficiency of a multicomputer is critically dependent on the performance of its interconnection network. This paper presents a new analytical model for circuit-switched cubic networks in the presence of correlated traffic pattern, which is a typical scenario for multimedia applications. A message in circuit switching may need a number of connection attempts before successfully setting up a path from source to destination. The proposed model uses the approach of superposing infinite correlated traffic streams to capture the effective traffic entering the network from a source, which includes the traffic generated by the source node and the traffic due to many connection attempts. Simulation experiments reveal that the model exhibits a good degree of accuracy under various operating conditions.
