摘要:企业网的建设是推动经济发展的迫切需求，同时，信息化程度的高低已成为当今世界衡量一个国家综合国力的标志；而国家电网作为国家重点企业，优良的网络环境更是必不可少；随着其业务的不断增加，需求量的不断增大，网络架构和网络设备的更新换代就显得非常重要；电网的网络改造不仅针对不断增加的业务、需求，同时对提高电网生产的安全性，信息的安全性同样非常重要。

　　　本次设计的调度数据专网作为调度核心业务数据通信平台，主要通过三层网络模型实现调度业务的实时性与可靠性，同时主要采用的协议有ospf，bgp，vpn，mpls等，实现电网内网数据的正常通信和数据安全。本次设计主要采用三层网络模型对地调、县调及接入站点进行实施，同时，将收到的数据统一传输到省掉进行分析检测，以保证整个开封地区调度数据专网的全网通信。全面满足国家电网调度业务的实时性、可靠性、安全性。

Abstract:The enterprise network construction is the urgent demand, promoting economic development and at the same time, the level of information has become a symbol of the world measure of a country's comprehensive national strength; and the national grid as a key state enterprises, the good network environment is essential; as the business continues to increase, increasing demand, it is very important to the network structure and network equipment renewal; network transformation grid not only increase in business, demand, at the same time to improve the safety of power grid production, information security is also very important.

　　　The design of the dispatching data network as scheduling core business data communication platform, mainly through the reliability and real-time scheduling service realization of three layer network model, while the main protocol used with OSPF, BGP, VPN, MPLS and so on, to realize communication and data grid intranet data security. This design mainly adopts three layer network model for adjustable, county and access site implementation, at the same time, unified transfer to omit detection data will be received, in order to ensure the whole network communication dispatching data network throughout the Kaifeng area. Fully meet the national grid service scheduling of real-time, reliability, security.
