QoS field equivalence classification in optical burst switched networks

Abstract

This paper proposes a QoS Field Equivalence Classification (FEC) scheme for Optical Burst Switched (OBS) networks. The proposed FEC scheme assembles bursts, based on the QoS requirements of the individual packets. To model a realistic assembly scheme, we simulate a network of queues with two queues and an assembler. The first queue receives the packets, which is served by the assembler, which in turn serves the second queue with the assembled bursts. In our simulations we use selfsimilar traffic for the incoming packets, and wavelength converters on both the ingress/egress and core nodes. We use ns-2 for our simulations.
