Abstract

The main goal of this article is to present a new model for planning of multi-service computer networks under particular consideration of QoS required by elastic and stream applications as well as their service differentiations at the routers. The model consists of several iterative integrated phases: (1) the IP traffic dimension phase deals with estimating the bandwidth needed for a given set of traffic demands; (2) the traffic mapping phase computes a optimal path used for delivering traffic demands and allocates the estimated bandwidth on this path; (3) the phase "capacity assignment and link dimension" deals with determination of an optimal physical network structure used for delivering the given traffic demands with required QoS. The model can be used for analyzing, optimizing, extending and for planning the computer to support new multimedia applications. This article also shows numerical results of some practical examples.
