| Abstract |
Building on the vast body of existing TCP models, we develop a novel versatile model that explicitly captures user heterogeneity, and takes into consideration dynamics at both the packet level and the flow level. It is described how the resulting multiple time-scale model can be numerically evaluated. Validation is done by using NS2 simulations as a benchmark. In extensive numerical experiments, we study the impact of heterogeneity in the round-trip times on user-level characteristics such as throughputs and flow transmission times, thus quantifying
the resulting bias. In particular, we investigate to what extent this bias is affected by the networks 'packet-level parameters', such as buffer sizes. We conclude by extending the single-link model in a straightforward way to the general network setting. Keywords: TCP, user heterogeneity, performance, throughput, round-trip times, packet level, flow level. |
