IP城域网中的RPR技术研究

摘要

In traditional packet switching architecture,there is a big delay and jitter.RPR ring on each node to simplify the handling of data packets between end-point operation.When a node failure or link failure,when,RPR protective measures to ensure the ring connectivity.RPR technology in broadband MAN,AG business applied.%在传统分组交换结构中，存在较大的延时和抖动。KPR环上的每个结点对数据包的处理简化了结点间操作。当结点失效或者链路发生故障的时候，RPR有保护措施，保证环网的连通性。KPR技术城域网在宽带业务、AG业务得到应用。
