摘要
提出了一个在EPON上实现多种业务传输的带宽调度方案 .借鉴了区分服务的方法 ,将服务分级并相应地将EPON的上行带宽分为预留带宽、高优先级和低优先级带宽 ,并采用了不同的分配策略 .仿真分析证明 。
We proposed a bandwidth scheduling scheme for multi services on EPON. With the method of differentiated Services (DiffServ) for reference, we classified network services into three classes and correspondingly classified the up transmission bandwidth of EPON into three portions: reserved bandwidth, high priority bandwidth and low priority bandwidth. Each type of bandwidth is allocated to user using different policy respectively. The simulation results prove that this scheduling scheme can support real time service and high burst data service.
