Equivalent bandwidth based-study of a multi-service optical network

In this article, we present an analytical study of an optical packet-switched network at two levels: at the border and in the core of the network. The aim of this paper is to predict the impact of handling different classes of service (CoS) on the network performance. The lack of memory in the core of optical network and the self-similarity nature of traffic are of great interest in this study. We use the equivalent bandwidth approach to carry out this goal. The analytical-based results are compared with those obtained by simulation.
