基于FDLs的边缘汇聚节点的性能研究

Investigation on edge aggregate node

随着全光接入网的不断发展,接入速率不断提高,对于边缘节点发送来的高速数据业务也必须进行流量梳理。为了适应未来全光高速网络接入的需求,基于光纤延迟线(Fiber delay lines,FDLs)结构,构造了一种简单高效的全光包交换网络边缘汇聚节点。并针对光线延迟线结构,提出一种新的主动缓存队列管理模型来分析节点性能,得到了与以往研究不同的结果。同时在对节点性能分析的基础上,提出一种新的FDLs的排列方式,在缓存深度相同的情况下,大大提高了FDLs的效率,实现了对到来的具有自相似性的数据业务的合理调配。

With the development of the optical access network, the access rate has been increased fast than ever. In order to meet the need of the high speed and all optical assessment, a new model base on the method of active queue management is put forward to investigating the performance of the edge node. And according to the analysis, a new FDL array is put forward, which can improve performance of the node and realize efficient packet scheduling under self-similar data traffic load.
