Using Time Warp for computer network simulations on transputers

The implementation of a Time Warp simulation frame is examined on a multitransputer machine. As computer networks can be considered as an integrated part of machine architecture, reliable evaluation tools for the development and study of protocols are a necessity. Simulation constitutes the only possible tool to obtain detailed information in this domain. The complexity of computer networks makes their simulation computationally complex and also very slow. That is why it is interesting to consider distributed simulation approaches. A major goal of this work is to determine whether the optimistic Time Warp algorithm is advantageous for the simulation of computer networks. The results presented indicate that the efficiency of the Time Warp technique seems to depend heavily on the characteristics of the simulation model.<>
