基于问询机制SDN控制平面失效检测研究
Research on inquiry mechanism based failure detection of SDN control plane
摘要
Abstract
Since the controller in the multiple SDN domains has the problems of long failure detection time,single check point and high misjudgment,an inquiry mechanism based hierarchical control plane failure detection algorithm of SDN is proposed. This mechanism can send the heartbeat message related with arrival time interval between controllers according to the probability dis-tribution,compare the arrival time interval at next time with predicted time interval,and judge whether the controller fails or not by means of querying mode. The simulation results show that,in comparison with the traditional detection scheme,the mechanism can shorten the failure detection time among controllers,effectively reduce the misjudgment probability of the multi-domain controller failure detection according to different failure probabilities to query the controllers with different quantity.关键词
