QoS-Supporting Deflection Routing Algorithm for Optical Burst Switching Networks
摘要
Abstract
A significant issue in optical burst switching (OBS) networks is contention resolution[1,2]. Deflection routing is one of contention resolution mechanisms in optical networks. This paper proposes an acyclic deflection routing (ADR) algorithm for OBS networks. The main idea of ADR algorithm is to determine the deflection ports based on the path-degree of nodes. ADR algorithm supports the ordered transmission of burst data and distributes the traffic of deflection paths among intermediate nodes with low path-degree. We also consider supporting QoS and propose the routing scheme for service differentiation, and investigate the performance of it in prioritized OBS networks through simulation.关键词
