摘要
测距技术是EPON系统的关键技术之一,其测量结果的准确度直接影响着上行链路动态带宽分配算法的效率乃至整个网络性能。分析了EPON系统中测距技术的必要性,介绍了基于多点控制协议的时间戳测距的基本原理,最后讨论了测距的延时补偿问题。
Ranging is one of important techniques for EPON, and its result affects efficiency of uplink dynamic bandwidth allocation and network performance directly. This paper introduces the importance of ranging for EPON, the principle of time - stamp ranging based on MPCP, and delay compensation.
