ABSTRACT
We simulate packet traffic on a large interactive growth net-
work designed to reflect the topology of the real internet. A
closed-loop algorithm (TCP) is used to define packet trans-
fer. We compare long range dependent and Poisson sources,
and the response of the network to changes in routing queue
service rate. By limiting queue length we simulate the ef-
fects of packet loss. We vary the pattern of hosts in the net-
work 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 character-
ising real scale-free networks.
