A Differentiated Shared Protection Algorithm Supporting Traffic Grooming in WDM Mesh Networks

摘要

摘要: 该文综合考虑WDM网状网生存性及业务量疏导,采用部分光路共享保护机制为低速业务提供满足其可靠性和带宽需求的连接,提出了一种基于波长分层图的支持业务量疏导的区分共享保护算法-部分共享保护业务量疏导算法PSPTG(Partial Shared-path Protection algorithm supporting Traffic Grooming).仿真结果表明:该算法可以较好地利用资源.

Abstract: Considering both the survivability and traffic grooming, a differentiated shared protection algorithm using wavelength layered-graph called PSPTG, which means Partial Shared-path Protection algorithm supporting Traffic Grooming, is proposed. In this algorithm, a shared protection scheme of partial lightpath based on link reliability is presented to meet the requests of reliability and bandwidth of connections. Simulation results show that the algorithm is efficient in terms of resources utilization.
