摘要
本文提出一种新型的EPON结构,可以实现ONU间直接对等通信。ONU之间的通信不再需要OLT的转发,提高了系统带宽利用率,降低包传输时延。同时提出了该网络结构下的保护倒换方案,实现快速故障检测和倒换.保证网络的高可靠性。
Proposed in this paper is a new structure of EPON, which is able to realize the peer-to-peer communication between ONUs. Because the communication between ONUs does not need forward by OLT, the System Band Utilization will be enhanced and the delay of the package transfer will be reduced. Meanwhile, focus on the protection switching strategy, which can realize the swift fault detect and the protection switch, to ensure the high reliability of this new structure.
