摘要
Abstract
For the problems that often occur during the switching process of the existing TT&C main and backup machines,such as the dual host servers/server software processes getting stuck and leading to switching failures,a hot standby seamless switching method for TT&C system is proposed based on daemon process and third-party detection.Firstly,the deficiencies of the existing master-standby switching strategy for TT&C system are analyzed.Secondly,the overall scheme,workflow,monitoring server software and daemon software of the proposed hot standby seamless switching method are designed and implemented,and the features of the method are analyzed.Finally,typical test scenarios such as communication abnormalities of the main and backup systems,host software jamming and database abnormalities are designed in conjunction with typical failure cases of the system,to validate the effectiveness and correctness of the proposed hot-standby seamless switching strategy for TT&C system.Test results show that the proposed method,compared with the"heartbeat"-based detection of the master-standby hot-switching method,has a 100%success rate of the master-standby switchover in the case of communication anomalies between the master-standby system,host software jamming and database abnormalities,which ensures the successful migration of the tasks after the occurrence of a failure,and provides a support for the improvement of the success rate of the execution of the tasks of TT&C system.关键词
