Markovian Analysis of a Synchronous Optical Packet Switch

ISBN 140209888X, 9781402098888We study switch architectures applicable to synchronous fixed-length optical packet networks in order to compare their performance in terms of packet loss ratio (PLR). We propose analytical models of these switches representing them as discrete time Markov chains and we solve them for incoming traffic with varying statistical properties. We compare performance measures computed using an analytical method with those obtained in an experimental way, by simulation, and we formulate conclusions on performance of considered switches. Our paper shows that Markovian models of future optical packet network architectures are efficient and that they can be applied as a tool to practical studies of network design
