频谱灵活光网络中多链路故障的主动定位算法

A Loading Algorithm with Power Constraints in Adaptive Modulation for V-BLAST Systems

频谱灵活光网络在很大程度上提高了频谱利用率,而如何提高频谱灵活光网络下的故障定位精度成为新的问题。多链路故障主动定位算法能够通过预处理事先得到故障可能存在的集合,从而主动发送检测业务,准确确定故障的位置。通过仿真对比,该算法较贪婪算法有着更高的故障定位精度,能够为故障保护和恢复提供更有力的支持。

Spectrum Flexible Optical Network greatly improves the spectrum utilization. How to improve the accuracy of fault location in FON has become a new problem. Active location algorithm for multi-link faults can obtain the set of possible faults in advance by preprocessing, so as to actively send detection services and accurately determine the location of faults. Compared with the greedy algorithm, the proposed algorithm has higher fault location accuracy and can provide more powerful support for fault protection and recovery.
