摘要

文章针对当前波分复用（WDM）光网络中业务量疏导技术研究的局限性

提出支持多优先级服务质量（QoS）的业务量疏导算法——MTGA。该算法基于业务流QoS的需求

将业务标记为不同等级

然后尽量选择占用跳数最少的通路来建立连接。仿真结果显示

与已有算法相比

MTGA能够有效地降低有时延约束连接请求的阻塞率。

Abstract

In view of the limitations in current researches on traffic grooming for WDM optical networks

a multi-priority QoS supported traffic grooming algorithm is proposed and studied in this paper.On the basis of the QoS requirement of traffic flow

the priority of the traffic is classified by this algorithm and arriving connection requests are routed over the paths with the least number of hops.Simulation results show that in comparison with the existing methods

the proposed algorithm can effectively reduce the blocking probability of the delay-constraint connection requests.
