Communication delay in wormhole-routed torus networks

A new analytical model for predicting message delay in wormhole-routed torus is presented. Unlike previous wormhole routing models, which mainly have been developed for uniform traffic, the model introduced in this paper computes message latency in the wormhole-routed torus in the presence of broadcast traffic. Results obtained through simulation experiments show that the model exhibits a good degree of accuracy in predicting message latency under different working conditions.
