摘要
分析了虚级联的传输延时和由LCAS协议引入的固定延时。在现有的SDH/SONET网络中,仅采用复用段保护或通道保护不能完全满足生存性的要求。基于它们各自的优点提出了组合保护的方法。通过仿真和分析,组合保护在恢复率和恢复时间上优于复用段保护和通道保护。
The transmission delay of virtual concatenation and the delay due to the LCAS protocol are analyzed. In current SDH/SONET networks, onLy multples section protection or path protection can＇t satisfy the need of survivability. The combination protection is suggested based,on the advantages of above two protection methods. By simulation and analysis, the combination protection is superior to the multiples section protection and path protection in the ratio and the time of protection.
