基于PCE的光网络跨域业务调度的设计与实现

Design and implementation of cross-domain traffic scheduling in optical network based on PCE

针对目前自动交换光网络(ASON)所面临的问题,指出路径计算单元(PCE)是解决这些棘手问题的有效途径。在描述了跨域调度的架构设计后,给出了基于PCE技术进行跨域调度路径计算的实现方案,最后通过仿真试验表明其优越性。

Aiming at the problem of ASON optical network at present, the paper points out that the path to the cell （PCE） is an effective way to solve these problems. After describing the architecture design of cross-do- main scheduling, the implementation scheme of cross-domain scheduling path computation based on PCE technology is presented. Finally, the simulation results show its superiority.
