Background
In a video monitoring field system, the front-end equipment is developed and communicated based on the SIP protocol specified in GB/T28181. The presence information is stored in directory data according to the requirements of the GB/T28181 standard. When a system (which may be a terminal or a superior platform server) needs to obtain the online status of a front-end device in real time, an existing mechanism mostly adopts the steps of sending a directory query request to a directory owner (which may be the front-end device or a platform server connected with the front-end device) first, and the directory owner returns all the front-end device directory data owned by the directory owner based on the request. After receiving all the node directory data, the system sends a directory subscription request to the directory owner. After receiving the request, the directory owner can actively send a directory notification to the system when the online state of the front-end equipment is changed, so that the function of acquiring the online state of the front-end equipment in real time is realized.
However, when the number of front-end device nodes of the directory owner is large, the problem that the online state acquired by the system is incorrect may exist. The reason is that when the number of front-end device nodes of the directory owner is large, the sent directory data volume is also large, and a certain time is needed for sending the directory owner. During this sending period, the directory owner has not received the directory subscription request, and if the online status of the front-end device changes, the directory owner does not notify the system, so that the online status obtained by the system is incorrect.
The chinese invention patent cn201410384194.x discloses a monitoring method of front-end application, which includes: when the terminal equipment runs the front-end application through the browser, the front-end application monitors the running state of the front-end application; when the front-end application monitors that the current running state meets a reporting trigger condition, the front-end application acquires data corresponding to the current running state and reports the acquired data to the Web server in a preset format through a reporting agent, so that the Web server organizes the data and then sends the data to the monitoring server, and the monitoring server performs corresponding processing according to the organized data. The embodiment of the invention also discloses a front-end application and a monitoring system of the front-end application. By implementing the embodiment of the invention, the front-end application can actively report the running state, and the efficiency of finding the problems of the front-end application is improved. However, it is not considered that if the number of front-end device nodes is large, the data sent to the system may not be consistent with the current state of the front end, which results in an incorrect state obtained by the system.
