基于市县调通一体化的网络优化改造分析

Analysis on Network Optimization for Integration of City and County Dispatch Communication

为加强市县调度通信一体化建设,消除县域通信传输网和调度数据网薄弱点,设计市县光通信网络和调度数据网络的优化改造方案。通过具体实施,建成县域分组传送网(packet transport network,PTN)光通信环网,节约了通信光缆传输带宽,提高了调度数据业务的通道承载能力,并通过建设县公司调度数据网第2汇聚点,实现市公司部分110 k V变电站和县公司全部35 k V变电站的调度数据双平面上联市公司,实现市县调度业务数据可靠传输,高速运行,为调度通信网向IPv6网络升级奠定基础;同时,对未来IPv6演进过程进行探讨分析。

For strengthening the integration construction of city and county dispatch communication, weak points of county communication transmission network and dispatching data network are eliminated, and optimization reconstruction scheme for city and county optical communication network and dispatching data network is designed. Through specific implementation, county packet transport network（PTN） optical communication ring network is built, transmission bandwidth of communication optical cable is saved, and bearing capacity of channel for dispatch data business is improved. And through the construction of the second convergent point of dispatching data network in county company, some of the city company＇s 110 k V substations and all the county company＇s 35 k V substations＇ dispatching data can be linked to the city company through a second path, and reliable and high-speed data transmission of city and county dispatch data business is also achieved, which lays the foundation for upgrading dispatching communication network to IPv6 network. Meanwhile, evolution process of IPv6 in the future is also analyzed in this paper.
