借助服务器集群技术构建了SDN控制集群,并在以控制集群为中心的网络拓扑基础上,设计出一种基于过渡规则集的流表更新方法。集群技术提高了控制系统的可靠性和效率,而更新机制通过逻辑验证,证实了其正确性和可行性,完全实现了更新一致性的要求。
Based on the server cluster technology, an SDN control cluster is constructed, and based on the control cluster, a flow table updating method based on the transition rule set is designed. Cluster technology improves the reliability and efficiency of the control system, and the updating mechanism verifies its correctness and feasibility through logical verification, completely fulfilling the requirement of consistency of updating.
