The interactive growth method is used to model the topol-
ogy of real networks. Packet traffic is simulated crossing
this network using the closed-loop packet transfer mecha-
nism Transmission Control Protocol. Comparisons are made
for traffic on regular and scale-free networks with open-loop
and closed-loop packet transfer mechanisms. Packet life-
times and queue behaviour for long range dependent sources
(LRD) are compared with short range dependent Poisson
sources (SRD) at the same loadings. The effects of varying
server strengths are studied as are the results of imposing
packet loss. The robustness of results is tested by varying
patterns of hosts and using different networks with similar
