SDH自愈保护原理研究与应用分析
Research on Self Recovery Protections for SDH and the Applications
SDH（Synchronous Digital Hierarchy，同步数字体系）技术能够取得飞速发展并广泛应用，其中一个重要的原因就是SDH系统具有自愈保护功能，极大提高了网络传输的可靠性。本文首先研究SDH系统中两种重要的自愈保护机制：SNCP保护和MSP保护的原理和应用。其次，EoS（Ethernet over SDH）是为获得高速带宽接入而诞生的技术，可在SDH上直接提供以太网接口。对于Eos能否使用SDH的SNCP自愈保护机制，文中做了深入的分析，并在实际环境中进行了的验证测试。验证测试结果表明，SNCP保护机制可以有效地保护EoS系统中的通道。
One of the main reasons why SDH(Synchronous Digital Hierarchy) has been developed rapidly and widely is that SDH deploys self recovery protections, which improves the stability of transmission. The article first expatiates on the theories that SNCP and MSP work and the applications of the two protections. EoS (Ethernet over SDH), which provides the interface for Ethernet over SDH networks, is used for high speed accessing. The article expatiates on the feasibility of using SNCP for Eos, and verification tests were carried out to verify this. The results show that SNCP is highly qualified to protect the EoS networks.
