摘　　要：针对电力通信网络承载的业务较多而导致的负载和安全性问题,提出了一种新型软件定义网络(Software Defined Network,SDN)架构。首先,集成OpenFlow和IEC 61850,采用冗余保护策略,保证网络中的多条链路或控制器发生失效时系统的正常工作;然后,利用缓存位置决策算法使系统的负载均衡;最后,利用流量隔离和VLAN进行安全性控制。实验结果及分析表明,提出的SDN架构有效提高了控制器和链路可靠性,且有效保证了电网系统的Qo S、负载均衡和安全性。For the load and safety problem which is caused by that electric power communication network carried more business, a software defined network framework is proposed. Firstly, OpenFlow is integrated with IEC 61850, and redundancy protection strategy is used to make sure the system working normally. Then, the cache location decision algorithm is used to ensure the load balancing of system. Finally, security control is done by using traffic isolation and VLAN. Experimental results and analysis show that proposed framework has improved the reliability of controller and links, and it has effectively ensured the Qo S, load balance and security of grid system.
