摘要
文章简要介绍了基于以太网的无源光网络(PON)这种新型接入网技术,简述了其优势,提出了业务分级的概念,并提出了基于OLT的上行带宽分配算法,通过动态请求分配机制,实现上行链路的高效利用。最后,通过建模仿真,分析该算法的延时特性。
This paper introduces a novel Ethernet based access technique,PON.Its advantages are introduced briefly and the concept of DiffServ is put forward.Then the upstream dynamic bandwidth allocation algorithm based on OLT(optical line terminal)is presented.Finally,the time delay is analyzed by modeling and simulation.
