OTN技术在Mesh拓扑网中的测试研究

Testing Research of the OTN Technology in the Mesh Topology Network

电网承载业务的快速增长对通信带宽提出了更高的要求,新形势下的电力通信传送网络必须具备大容量、长距离及高稳定性能。文章介绍了满足电网承载业务新需求的OTN技术的特点,包括其电层开销帧结构以及系统站点性能,并对OTN支持的智能ASON保护机制进行了实际网络测试。测试结果表明,合理的选择保护机制可以很好地缩短业务保护倒换时间,对OTN在电力通信骨干网中的应用具有指导意义。

The fast growth of electric power network services brings a higher requirement to the telecommunication bandwidth. Under the new circumstance, electric power telecommunication transport network must have the properties of high capacity, long distance and high stability. This paper introduces the OTN technique satisfying all the above requirements, including its electric layer payoff structure and system state properties. Further, the ASON protection scheme supported by the OTN is tested in a real network. The testing results show that choosing the protection schemes reasonably can greatly reduce the protection shift time, which has a guiding significance for applications of the OTN technology in Jilin electric power telecommunication backbone network.
