| 摘 要： | IEEE 802．17工作组正在标准化一种新的环型网络体系结构——弹性分组环(RPR)，它主要应用在城域网和广域网的传输中。RPR是一种可利用光传输通道的面向数据通信的新技术，它不但保留了SONET／SDH的可靠性，而且比传统的SONET／SDH能更有效地分配带宽和传输数据。文中在简单介绍了RPR的工作原理之后，主要讨论了RPR中的优先级方案、公平算法和拓扑识别等关键技术。

| Abstract: | IEEE Working Group 802.17 is standardizing a kind of new ring topology network architecture called the Resilient Packet Ring,and it is used mainly in metropolitan and wide area networks. RPR is a new data-oriented technique that can be used to transmit data information in optical channel. It can not only keep the reliability of SONET/SDH,but also can allocate the bandwidth more fairly and transmit data more effectively. After simply introducing the principle of RPR,this paper mainly discusses the key techniques of RPR,such as RPR priority scheme,fairness algorithm and topology discriminating mechanism. |
