接入环双节点SNCP保护组网应用分析

Access Ring Double-nodes SNCP Protect Networking Applications Analyzed

分析了利用接入环双节点SNCP保护组网的优缺点。在设计项目中采用接入环双节点SNCP保护方式组网,以其双发选收特点,双归属上连汇聚层,避免了单节点失效、下挂业务丢失。有效地进行了风险分担、光缆断纤自动保护,从而提高了网络的可靠性、安全性。因此,利用SNCP保护是首选的可适用于各种网络拓扑结构且倒换速度快的业务保护方式。

Analysis and use access ring double-nodes SNCP is used to protection networking of the pros and cons.Methods：This design project uses access ring double-nodes SNCP ways to protect network,as well as its double transmit elects to receive the characteristic,double adscription connect on the convergence layer,avoid single node failure,hang business lost.Results：Effectively conducted risk sharing,automatic protection fault fiber optical cable,thereby increasing the network’s reliability and security.Conclusion：Using SNCP is preferred by the applicable to various network topology structure and fast speed switch to service protection way.
