天津电力通信网NEC网管系统优化方案

The Optimization Scheme of NEC Network Management System in Tianjin Power Communication Network

随着电力通信网日益庞大和复杂,实现一套高效可靠的网管系统尤显重要。文章结合天津电力通信网中的NEC设备网管情况,制定网管系统优化方案。利用综合业务数据网平台并使用MPLS VPN技术,将网络划分为不同的子网,减少路由表条目,解决了部分网元因路由表溢出而发生脱管的问题。通过对网络结构的调整,增加主调、备调网管间三层VPN通道,改进了备调网管的备用功能。目前已经验证方案的有效性,为其他网管系统的优化提供了新的思路。

In recent years, power communication networks are becoming larger and more complicated, thus it is necessary to achieve an efficient and reliable network management system. This paper introduced a method to improve the reliability of network management system, considering the actual situation of NEC-SDH network management system in Tianjin Electric Power Communication Transmission Network. To solve the problem that some network elements drop off the pipe due to the routing table overflow, we used integrated services data network platform by MPLS VPN technology to divide the network into different subnets and to reduce the routing table entry. By restructuring the network, the three VPN tunnels between the primary and backup network equipments were increased, and the network backup equipment transfer function was improved. The effectiveness of this scheme has been verified, introducing a new method to optimize other network management systems.
