摘要
传统的SDH光纤传输系统由于其高安全性,高可靠性,低时延等优点而在电力通信网中被广泛应用,但其传统的环网保护(MSP,SNCP)方式无法抗多点断纤,不能满足智能电网发展的更高要求。为了解决这些问题,文中基于智能光网络(ASON)设计和OSPF洪范协议的优化,创新性研发出2M ASON新技术。2M ASON是基于2M的业务实现的端到端的ASON,支持低阶告警触发重路由,当拼接点节点失效时,2M业务可以自动选择合适的VC12通道,从而实现2MASON业务抗节点失效。另外同时多个2M业务共享1个VC4,相对于传统ASON,带宽利用率最大提高63倍。国网芜湖繁昌县供电公司应用测试结果表明:正向业务实际测试结果为23ms;网络的反向业务实际测试结果为6ms。
The traditional SDH optical fiber transmission system due to its high security, high reliability, low latency, etc. is widely used in electric power communication network, but the traditional way of ring network protection （MSP, SNCP） cannot resist more broken fiber, can not meet the higher requirement of the smart grid development. In order to solve these problems, this paper based on the intelligent optical network design and optimization of OSPF hong fan agreement ASON, innovatively developes 2M ASON technology. 2M ASON is based on the 2M business implementation of end-to-end ASON, supports the low-order alarm trigger reroute, when splicing point node failure, 2M business can automatically select the appropriate VC12 channel, so as to realize 2 Mason business of node failure. And at the same time more than 2M business share a VC4, compared with traditional ASON, maximum bandwidth utilization improves 63 times. In Wuhu Fanchang county electric power supply company, the application test results show that the positive business actual test results for 23 ms. Actual test results for the network reverse business 6 ms.
