摘要

为对动态业务快速有效疏导，并实现智能区分保护，提出一种基于分簇业务量疏导的动态区分保护策略。该策略基于极大独立集将网络有效分簇，减小疏导寻路耗时；同时将分层辅助图、波长剩余容量矩阵及簇汇聚层相互协同，对簇内簇间业务疏导，实现资源的合理规划，提高疏导效率；其后通过感知各优先级业务比例划分波长链路重要度，设计智能P圈进行区分保护。仿真表明，所提策略能更充分利用资源，且随负载增加有较好的阻塞率性能。

Abstract

To make dynamic traffic grooming faster and more efficient

and achieve an intelligent differentiated protection

a differentiated protection strategy with dynamic traffic grooming based on clustering(DPS-DTGC)was proposed.The whole network topology was allocated some clusters based on maximal independent set

in order to reduce the routing time consumption.Meanwhile

by the cooperation of layered auxiliary graph

residual capacity matrix and cluster aggregation layer

the traffic in inter- and intra- clusters would been groomed to realize the reasonable planning of resources and the higher efficiency of grooming.Furthermore

according to the proportion of different priority traffic in one wavelength

the link importance was evaluated and a smart P-cycle was designed to give differentiated protection to the link.The simulation results show this strategy can make a better utilization of network resource.And with the increase of network load

it will gain a good performance in blocking rate.
