On the Impact of Scale-Free Structure on End-to-End TCP Performance

In this paper, we analyze end-to-end TCP performance (i.e., Sending rate, packet loss probability, and roundtrip time) of TCP flows on a network with scale-free structure. Using a numerical example of our analysis, we show that the scale-free structure contributes to improve the end-to-end TCP performance, and that such performance improvement is caused by reduction in the average path length and also reduction of traffic intensity at a bottleneck link.
