摘要
针对WDM光网络的单波长预留协议中经常出现多个连接请求竞争同一波长而产生冲突的问题,提出将多波长预留概念扩展到分离预留协议以及基于马尔可夫的分离预留协议(MSRP)中。首先,讨论了三种多波长方案,利用多波长进行可能选择和进一步分离,从而减少请求的整体阻塞;然后,将它们与对应的单波长协议进行比较,发现单波长协议的性能得到了明显改善;最后,仿真实验使用三种多波长协议建立光路,比较结果表明,多波长MSRP执行效果最好。
In order to reduce or avoidthe conflict caused by that multi-link request often compete with the same wavelength unwittingly in WDM optical networks,the multi-wavelength reservation concept was proposed to be applied into the split reservation protocols （SRP） and the Markov split reservation protocols.Firstly,three multiwavelength methods were discussed,and multi-wavelength was used to do possible choices and further separation so as to reducing the request of the whole block.Then,they were compared to their single wavelength protocols.The results show that the performance of single wavelength protocols were more evidently than proposed three multiwavelengths.Finally,optical paths were established using the three protocols by simulation experiments,comparison results show that the multi-wavelength MSRP has the best performance.
