Performance assessment of signaling protocols in optical burst switching mesh networks

Abstract

This paper presents a performance evaluation of just-in-time (JIT), just-enough-time (JET), Jumpstart and Horizon signaling protocols in optical burst switching (OBS) networks with mesh topologies. The analysis is focused on the following topologies: rings, chordal rings, mesh-torus, NSFNET, ARPANET and the European Optical Network. It is shown that choral rings with smallest diameter lead to best network performances. For 16 nodes and 64 data channels, the nodal degree gain due to the increase of nodal degree from two (ring) to three (chordal ring with smallest diameter) is about three orders of magnitude in the last hop of both topologies. Mesh networks with a number of nodes ranging from 14 to 26 nodes have been analyzed and it was shown that chordal ring topologies with smallest diameter are very suitable for this kind of networks. It is also observed that, for the cases under study, the network performance for JIT, JET, JumpStart and Horizon is very close. © Springer-Verlag Berlin Heidelberg 2004.
