Modelling of TCP packet traffic in a large interactive growth network

We simulate packet traffic on a large interactive growth network designed to reflect the topology of the real Internet. A closed-loop algorithm (TCP) is used to define packet transfer. We compare long range dependent and Poisson source, and the response of the network to changes in routing queue service rate. By limiting queue length we simulate the effects of packet loss. We vary the pattern of hosts in the network and compare results from different networks generated using the same parameters. The two source types produced very different results highlighting the importance of LRD source models. Results also showed robustness with respect to changes in network and host pattern. This demonstrates the validity of the interactive growth method for characterising real scale-free networks.
