基于MSTP传输网的DCN网络优化的研究

随着电力企业基于同步数字体系的多业务传送平台(MSTP)光传输网络规模的不断扩大,设备数量迅速增加,在一个光传输网的管理域内可能出现数百个网元节点,使数据通信网络(DCN)的规模过大,出现告警性能数据不能及时上报、网元频繁脱管、网管操作速度变慢等现象。文章根据云南电力通信光传输网的组网结构和DCN网络现状,合理规划该光传输网的DCN网络,提出了DCN网络的子网划分方法,解决了网管信息丢失、网元脱管等问题,增强了光传输网的运行可靠性和有效性。

Research on DCN Network Optimization Based on MSTP Transmission Network

With the increasing expansion of the MSTP optical transmission network based on the synchrounous digital hierarchy and the rapid increasement of network devices in power enterprises, hundreds of network elements may appear in a single management domain of a optical transmission network, which results in huge scale of data communication network （DCN）, latency of alarming data, loss of network nodes and low speed network management operation. Taking the networking structure of power communication optical transmission network and the situations of DCN in Yunnan Power Grid into consideration, this paper proposes a subnet partition method for DCN to reasonably plan the DCN of the optical transmission network in order to solve the above issues and enhance the optical transmission network operation reliability and effectiveness.
