以河北电力调度数据网为例，对调度数据网络规划建设过程中涉及的技术问题，如网络拓扑、IP（internet protocol）地址规划、OSPF（open shortest path first）协议和VPN（virtual private network）部署等进行探讨，并提出解决方法和基本原则。

Taking the Hebei power dispatch data network (SGDnet) as an example, the paper discusses the technical problems encountered in planning and construction of dispatch data network such as network topology, internet protocol(IP) address planning, open shortest path first interior gateway protocol (OSPF) and virtual private network (VPN), and proposes solutions and basic principles.
