摘　　要：介绍了OTN在电力通信网络中的应用技术特点,并给出不同网络拓扑结构下适用的保护机制;通过搭建传统SDH网络与Mesh结构下的OTN网络相结合的网络测试环境,对SDH SNCP与OTN智能ASON相协作的网络中的不同业务保护机制进行了性能比较。结果显示,这种智能保护可以抗击多次业务中断,且能够满足小规模网络中50 ms倒换需求,为电力通信网络业务传输提供了坚强的保障。This paper introduces the application characteristic of the OTN technology in the electric power telecommunication network, and gives the protection mechanisms applicable to different network topologies. Through constructing a network testing circumstance with a combinatory of the traditional SDH network and the OTN network using the Mesh structure, the performance of various business protection mechanisms in the hybrid network of the SDH SNCP and the OTN intelligent ASON are compared. The results show that the intelligent protection mechanism can not only counteract many times business interruption, but also meet the needs of less than 50ms switching time in a small scale network, which provides a strong guarantee for transmission businesses in the power communication network.
