摘要

针对未来的通信网络将趋于扁平化并支持各种业务的需求

将多线速应用到城域OTN（光传送网）的业务疏导算法中

对高、低带宽业务进行不同的业务疏导。提出了适合解决大中型网络业务疏导问题的启发式算法

将该算法应用于城域OTN中

并将多线速与单线速网络的结果进行比较

结果证明多线速OTN城域网的业务疏导算法可以降低网络建设成本。

Abstract

Future telecommunication networks are expected to be flat-structured and support a variety of traffic demands.In line with the diversified demands

the Mixed Line Rate（MLR）is applied to the metro OTN traffic grooming algorithm

grooming services at the different bit-rates.A heuristic algorithm is proposed for the service grooming in large and medium-sized networks.Then this algorithm is applied to metro networks and the results in MLR and Single Line Rate（SLR）networks are compared

which show that this algorithm applied in MLR OTN metro networks can reduce the network construction cost.
