基于流量分割的IP over WDM业务疏导机制研究

Traffic grooming mechanism in IP over WDM networks based on traffic partition

在IP over WDM网络的业务疏导中,针对大容量的高优先级业务接入阻塞率很高的问题,提出了一种基于流量分割的业务疏导机制。该机制将一个业务请求的总流量分割为多个部分,然后根据光路径的传输时延来选择一组恰当的子路径作为业务路由。仿真结果表明,该机制能有效地降低目标业务的阻塞概率,并提高业务接入的公平性。

In traffic grooming of IP over WDM networks, a traffic grooming mechanism based on traffic partition is proposed for solving the problem of high blocking probability when high priority traffics with high capacity access. The mechanism partitions a traffic flow into several parts and spreads it over multiple paths that are selected by considering delays over different paths. The simulation results show that it can effectively lower blocking probability for high priority traffics and improve access fairness.
