摘要：

本文根据当前宽带多业务的需求，分析了EPON系统承载多业务的必要性，提出了衡量EPON系统调度机制优劣的因素。在介绍了两种现有调度机制工作原理的同时，根据各方面因素对这两种调度机制的优劣进行了分析，最后给出了EPON系统中这两种调度机制目前适用的网络场景。

Abstract:

In this paper,basing on the current demand for broadband multi-service,the necessity of multi-service delivery over EPON system is analyzed,and an approach to measure the efficiency of EPON system scheduling mechanism is put forward.After introducing the two principles of the existing scheduling mechanism,according to various factors both advantages and disadvantages of scheduling mechanisms are analyzed,and fina11y the network scenarios applicable currently are presented which were we11 matched with these two EPON system scheduling mechanisms.

Key words: OLT, ONU, LLID, DBA, scheduling mechanism
