电力无线虚拟专网组网架构及IP地址分配研究

文章结合电力通信网络边缘接入的现状和应用特点,在大量研究目前网络技术及通信运营商组网架构的基础上,深入探讨了适用于承载电力行业无线应用的电力无线虚拟专网的网络架构、IP的分配策略及安全防护措施。文章首先从接入网、传输网和核心网3个层面分析了电力无线虚拟专网网络架构,然后针对IP地址分配,提出了适合电力无线虚拟专网的IP地址分配方式和IP地址使用策略,最后根据企业对网络安全的特殊要求,提出了包括终端安全、网络安全、边界安全及应用层安全等的多种安全措施,为电力及其他行业无线虚拟专网的建设提供了参考。

Study of Network Architecture and IP Address Allocation of Wireless VPN for Power Grid

Considering electric power communication network borders and application characteristics of power grid, and based on the study of the existing network technologies and communication network architectures, this paper deeply investigates network architecture of wireless virtual private network （VPN） for power grid, IP address allocation methods and safety precautions. Firstly, the network architecture is discussed on three sides including wireless access network, data transmission network and core network of business. Then the IP address allocation method and IP address usage policy are proposed lbr wireless VPN for power grid. Finally, a set of security measures including the terminal security, network security, border security, application security and etc. are presented to satisfy the special demands for network security, which can be a reference for wireless VPN application in power grid and other industries.
