摘要
通过分析SDH自愈环网在不同保护机制下的原理,基于链路串并联结构,利用可靠性框图对不同SDH自愈环网的有效性分别建立了模型,并进行了详细的比较分析。最后对具体的例子仿真计算,并对仿真结果进行了分析和讨论。
The principle of SDH self-healing ring network with different protection mechanism was analyzed, based on the series structure and parallel structure, the availability module of different SDH self-healing ring network was built by Reliability Block Diagram in this paper. Finally, a simulation on actual example was analyzed and discussed.
