只要MSTP(多业务传送平台)网络中数据业务开通了LCAS(链路容量调整方案),将业务部分VC(虚容器)开通在传输网络的保护通道,即使保护通道上的部分VC中断,由于用户FE(快速以太网)口是从64kb/s～100Mb/s自适应速率,用户的数据业务不会收到影响,只是速率降低。等到故障恢复,保护通道上的部分VC恢复,用户的速率恢复正常。在这个过程,用户的业务不会中断,但却提高了传输网络的运送数据的能力。
As long as LCAS (Link Capacity Adjustment Scheme) is enabled for the data service in the MSTP (Multi-Service Transport Platform) network, the VC (Virtual Container) of the service part is opened in the protection channel of the transmission network. Even if some VCs in the protection channel are interrupted, FE (Fast Ethernet) port is from 64kb / s ~ 100Mb / s adaptive rate, the user’s data services will not be affected, but the rate of decline. Wait until the fault recovery, protection VC part of the recovery channel, the user’s rate back to normal. In this process, the user’s business will not be interrupted, but it improves the ability of the transport network to deliver data.
