Study on contention resolution with fiber delay lines in OBS network

摘要

In this paper, we study the optimum configuration of FDL in OBS node, resource-assignment ways of the node out-ports and the allocation of optical buffer resource. We evaluate them in terms of burst loss probability. Through compare the performance, the node port reserving modes and the use ways to FDLs are studied first. Analyze the impact of granularity on performance in several resource assignment models. For the first time, void-filling and greedy reserving are integrated investigated. Based on the results, the modified void-filling resource allocation scheme is proposed.
