摘要
介绍了电力调度数据网的网络拓扑和层次规划,对发电业务的分区进行了详细说明。业务的接入采用IP+SDH+光纤技术体制,并运用开放式最短路径优先协议OSPF(Open Shortest Path First)和静态路由相结合的方案提高转发效率。出于安全性考虑,根据发电业务的特性部署专用通道,实现业务的隔离,同时采用网络安全技术加强网络安全访问控制,利用专用安全设备防止病毒入侵和恶意攻击,保证数据网在物理层、网络层、系统层及应用层的安全,最后在常规二次安防的部署方案基础上给出几点建议。
This paper introduces the network topology and hierarchical planning of the dispatching data network,and explains the division of the power plant business.It adopts IP＋SDH optical fiber technology system,and using the Open Shortest Path First with static routing scheme to improve the forwarding efficiency.For security considerations,the dedicated channels are deployed according to the power plant business.
