摘要
随着电力系统信息通信灾备中心的建立,电力业务对时钟同步提出了更高的要求,时钟同步网对于电力通信网络起着至关重要的支撑作用。文章说明了未来OTN(光传送网)设备在电力通信网中大规模部署逐步替代SDH(同步数字体系)网络之后,OTN支持时钟同步传递的必要性。在进行同步技术分析的基础上,提出了基于OTN+PTN(分组传送网)的统一同步网络组网模型,并进行了相应的系统测试,测试结果表明,OTN+PTN组网模型能够满足电力业务的同步需求。
In recent years, with the establishment of power system information disaster recovery centers, still higher require- ments are placed on the clock synchronization for electric power business and the clock synchronization network plays a vitally important supporting role for the electric power communication network. This paper explains the necessity of the OTN support to clock synchronous transport when SDH networks are gradually replaced by OTN equipment deployed in large scales in power communication networks in the future. On the basis of analyzing the synchronization technology, it proposes a unified OTN＋ PTN-based synchronous network model and conducts the relevant system tests. The results show that this networking mode satisfies the synchronization requirements of the electric power business.
