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。
The advantages and disadvantages of using two-node SNCP to protect the network are analyzed. In the design project, an access ring dual-node SNCP protection networking is adopted. Due to its double sending and receiving feature, the dual-homed uplink even convergence layer avoids single node failure and loss of downlink services. Effective risk sharing, fiber optic cable broken fiber automatic protection, thereby enhancing the network reliability and security. Therefore, using SNCP protection is the preferred service protection method that can be applied to various network topologies and switches fast.
