Abstract :
A procedure is presented for estimating online marginal packet delays through links with respect to link flows without making such assumptions, based on perturbation analysis. No knowledge of network parameters is required (arrival rates, link capacities). This is used in the context of a minimum-delay distributed routing algorithm for real-time implementation. The effect of the algorithm step-size and observation period parameters is investigated experimentally. Results demonstrate the adaptivity of the approach. It is seen to compare favourably to well-known analytical approximations.<>
