Comparison of OBS protocols

Abstract

In this paper, we give an overview of all-optical networks. The classification of optical burst switched networks (OBS) which is one of the WDM schemes is proposed. We compare the performance of different traffic models on definite signaling protocols of OBS. These traffic models are IP/burst and multimedia traffic. As multimedia traffic we evaluate the performance of video traffic through all-optical network. We also investigate the affects of other traffics and network characteristics on application performance. The examined signaling protocols are JIT, JET and Horizon. We apply the exponential and hyperexponential distributions on these traffics for producing the inter-arrival times of the packets. We present a communication between a source client node and a destination client node over an ingress and one or more multiple intermediate switches. Our paper also includes burst setup, burst setup ack and keepalive message types. We propose a framework for calculating the dropping rates. As a result, we compare the signaling protocols according to the burst drop rates
