摘要
ONU注册是10G EPON系统正常运行的前提,在不影响系统正常运行的情况下实现新ONU自动注册或故障ONU重新注册是PON系统的突出优点。文章分析了10G EPON系统的双速率MAC协议栈及10G EPONMPCP控制帧相对于1GEPONMPCP控制帧结构所作的扩展,描述了10G EPON系统ONU注册的基本流程,重点讨论了OLT开窗控制和ONU注册响应的基本原理。
ONU anto-discovery is the precondition for the normal operation of an 10G EPON system..It is the excellence of PON systems to discovery new ONU without any disturbing to the normal ONUs in the sustem. In this paper, we analyne the dual rate MAC stack of 10G EPON system and the extendability of MPCP protocol in order to support auto-discovery of different kinds of ONUs ,describe the register process of 10G EPON system especially.
