Paper Abstract

Optical Burst Switching (OBS) has been proposed to be a competitive switching technology for DWDM networks. However, the abrupt burst for large traffic loads will result in unbearable performance degradation in the traditional JET network. To combat with the load sensitivity, a wavelength-routed OBS (WR-OBS) network architecture was confirmed effective. In this paper, we have proposed a distributed control WR-OBS network architecture combining JET protocol with a two-way reservation method. Based on this architecture, two new resource reservation protocols are compared by evaluating their performance. Then based on the Reduced Load Approximation, which is often used in the analysis of the circuit switch network, a novel analysis method was derived to evaluate the blocking performance of the network. And then we have developed a simulation model to evaluate the performance of the network and validate the proposed analysis method. Analytical and simulation results have indicated that the proposed architecture outperforms the traditional JET OBS network in burst blocking probability with a good trade-off between efficiency and complexity.
