基于QoS的WDM网络中多等级服务问题研究

QoS Realization with Multi-class Service in WDM Networks

针对WDM网络中波长和路由分配(RWA)问题,提出了一种具有QoS保证的多等级服务的方法。通过使路由器根据路由表为到达的分组数据提供等级服务,不仅可以有效地解决WDM网络中分组数据阻塞的问题,实现区分服务,而且可以提供更好的QoS保证。文中也给出了计算机仿真结果。

The purpose of this paper is to propose a novel method of multiclass service that may provide QoS guarantee. By looking up the routing table, the routers may realize the multiclass service for different QoS requests, and the method may also mitigate the blocking of packets substantially in the WDM network. Simulation results are also analyzed and compared.
