Stochastic Analysis of the Packet-Pair Bandwidth Probing Event under Heterogeneous Cross-Traffic

An analytical model of packet-pair bandwidth-probing under heterogeneous traffic is compared with a discrete-event simulation. The arrival of each packet-type is governed by an independent Poisson process, such that the aggregate distribution is approximately Gaussian. The waiting-time can be resolved into two components: A transient component representing the emptying process, and an equilibrium component representing the return to a steady-state distribution. The simulated waiting-time and dispersion characteristics agree closely the model’s predictions.
