ATM over SDH网络中自愈算法的研究

Research on self-healing algorithms and their performance in ATM over SDH network

随着SDH设备的大面积采用以及大容量的ATM交换机的不断商用化,以高速光纤传输线路和高吞吐量的网络交换节点为特征的现代通信网络格局已经形成。文章从实际角度出发,分析了ATM层网络与SDH层网络自愈恢复的多种算法及其性能,并在此基础上,研究了ATMoverSDH宽带网络中的恢复控制策略和混合升级机制。

With the SDH equipments are applied widely and the large capacity ATM exchangers are constantly commercialized,the modern communication network pattern has been formed with the characteristics of high-speed transmission by optic fiber circuit and high throughput in network switch nodes.This article analyses and summarizes several kinds of healing algorithms and their performance about ATM and SDH network.On this basis,the recovery controlling tactics and mixed upgrading mechanism of ATM over SDH network have been researched.
