Reliability modeling and performance evaluation of variable link-capacity networks

Abstract

This paper presents a composite performance index for communication networks with variable link-capacities. This index is based on link reliabilities and multiple-capacity link-states. Source-to-terminal success is the ability to provide connectivity with a certain traffic-carrying capacity. This index is useful for determining the performance of networks with links operating with residual traffic-carrying capacity and gives a good idea of the available resources for a particular s-t connection. An algorithm is given to evaluate the composite performance index.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
