OBS网络基于光缓存的多优先级业务冲突研究

Study on optical buffer-based multi-priority traffic contentions in OBS networks

光突发交换(OBS)网络是下一代IP over WDM光网络的典型代表。文章对配置有光缓存的OBS网络核心节点中发生的多优先级业务冲突问题进行了性能分析,给出了不同优先级数据包的丢失率和平均等待时延,研究结果可以为OBS网络的实用化提供理论参考。

The Optical Burst Switching（OBS） network is a typical representative of the next generation IP over WDM networks.In this paper,the performance analysis is made of the multi-priority traffic contentions in the optical buffer-equipped core node in OBS networks.The packet loss probabilities and average waiting latency for different priority traffics are given.The results provide theoretical references for the realization of OBS networks.
