Abstract |
As the performance of computer networks becomes similar to the performance of multiprocessors, the efficiency of the routing methods used, is also converging. Methods used for networks can also be applied for a high performance network having similar performance to a multiprocessor. The ATM method, which is frequently used in computer networks, combined with credit based flow control can be used in multiprocessors where popular routing method is wormhole. Data flow is different for the two methods and that is the main reason that the two methods have different performance. In our work we measure and compare the performance of ATM with credit based flow control and wormhole. The two kind of switches were modeled and a simulator was created based on those models. The models are detailed, realistic and they describe the operations of a switch in one clock cycle. We study the cell delay and throughput for networks consisting of either ATM or wormhole switches under uniformly distributed (poisson), bursty traffic and with hot spots at the exits of the network. We also study the performance as the network or the switches become larger. The results show that a network consisting of ATM switches have better performance than the one consisting of wormhole switches, having smaller delays and better throughput in analogous configurations. For ATM networks an improvement of performace is achieved when more than one lane is available in the network.
