基于EPON的公平带宽分享算法及其应用

考虑光学开放接入网（optical open access network）中的公平性，将最大最小公平算法用到双向服务等级协议（D-SLA）中，提出了一种基于以太无源光学网络（EPON）的易于实现的双向服务等级协议公平带宽分配算法。算法使用了两轮分配，通过分级管理确定首要SLA和次要SLA，对业务提供商和用户进行分级区...

Fair bandwidth sharing algorithm based on EPON and its application

For the fairness of optical open access networks,after applying the max-min fair algorithm in the dual-service level agreement algorithm,an ethernet passive optical network(EPON)-based D-SLA fair bandwidth allocation algorithm is proposed,which is easy to implement.This algorithm uses the two-round allocation.By level classification,the primary SLA and the second SLA are confirmed.And then the service providers(SPs) and users are treated in different levels to satisfy the mutual fairness request at the same time.The simulation results are given to prove that this algorithm reaches the expected goal and is feasible to satisfy the fairness request for both SPs and users.Evaluating the fairness by fair parameter,this algorithm is superior to the others.Meanwhile,it′s reasonable and practical in applications.
