Description

A method and system for pushing alarm information of cloud AC

technical field

The invention relates to the field of communication technologies, and in particular, to a method and system for pushing alarm information of a cloud AC.

Background technique

At present, the trend of software-defined network and network function virtualization based on virtualization technology is becoming more and more clear, and many research institutions, communication equipment manufacturers and communication service providers have begun to study the reconstruction and deployment of network service functions under traditional modules in the cloud. For example, The AC (Access Controller, access controller) is deployed in the cloud, referred to as the cloud AC. The difference between the cloud deployment and the traditional mode deployment is that the AP (Access Pointer, access node) needs to be connected to the AC across the Internet.

During the communication between the cloud AC and the AP device, when the cloud AC receives an alarm event reported by an AP device, it needs to generate alarm details according to business rules, and it needs to push the alarm information to the user's alarm monitoring page in time, so that Operation and maintenance personnel deal with relevant alarms in a timely manner. However, at present, since the connection between the AP device and the cloud AC is based on the HTTP protocol, if the front-end page needs to communicate with the back-end server, it needs to use a long connection, that is, the page actively initiates an HTTP connection, and after the back-end returns a message, the HTTP connection is disconnected Open, the front-end page needs to initiate an HTTP request again to establish a connection. This method increases the pressure on the connection processing of the back-end server. The real-time sending of messages is not high, and the communication exception handling between the front-end and the back-end is very complicated.

Specifically, when an alarm event occurs on an AP device, it will report the alarm event to the cloud AC. After receiving the alarm event, the alarm module of the cloud AC generates alarm information according to business rules. Device information (for example, device number) of the alarm event, alarm time, and content of the alarm event, etc.

Step 102, the cloud AC pushes the generated alarm information to a message middleware. In a preferred embodiment of the present invention, the cloud AC pushes the alarm information to the STOMP message middleware.

Step 103, the front end connects with the backend server through the WebSocket protocol, and registers with the backend server through the WebSocket protocol to generate user management information, the user management information at least includes user information and device information corresponding to the user information, such as registered user A, whose corresponding The device information includes device A, device B, device C, and so on.

Step 104, the background server obtains the alarm information from the message middleware, and searches for the device information corresponding to the alarm information in the registered user management information according to the alarm information. Specifically, the background server obtains the latest alarm information from the STOMP middleware. For example, the background server can obtain the alarm information within three minutes from the STOMP middleware every three minutes, and extract the device information from the alarm information. Device ID Check whether there is the device ID and its corresponding user information in the registered user management information.

Step 105, when the device information corresponding to the alarm information and the corresponding user information are found, the background server sends the alarm information to the front end of the corresponding user through the WebSocket protocol. That is to say, when the user information corresponding to the device number is found in the registered user management information according to the device number of the device information, the background server sends the alarm information to the front-end page of the corresponding user through the WebSocket protocol.

Preferably, a method for pushing cloud AC alarm information of the present invention further includes the following steps:

The front-end monitors the WebSocket connection status with the back-end server in real time or periodically, and actively tries to use the WebSocket protocol to reconnect to the back-end server after the connection is interrupted.

Preferably, a method for pushing cloud AC alarm information of the present invention further includes the following steps:

The backend server periodically sends heartbeats to the frontend to monitor the connection status of the frontend user. After confirming that the frontend user is disconnected, it logs out the user management information and closes the connection channel.

FIG. 2 is a schematic diagram of message transmission according to a preferred embodiment of a method for pushing alarm information of a cloud AC according to the present invention. The details are as follows: 1. The front end connects to the backend server through the WebSocket protocol, the frontend user logs in and registers through the page, and registers the user management information on the backend server through the WebSocket protocol, including the user information and the information of each device corresponding to the user information, that is, each user can manage Several AP devices, specifically, the present invention can use NODE.JS to establish multiple users, each user manages several AP devices, and the background server just sends the alarm information to the relevant users; 2. The background server sends the alarm information from the STOMP message server (STOMP message middleware) obtains the latest alarm information, extracts the device information from the alarm information, searches the registered user management information for the user information corresponding to the device number according to the device number of the device information, and registers it in the registered user management information. When the user information corresponding to the device number is found in the user management information of the device, the alarm information is sent to the front-end page of the corresponding user through the WebSocket protocol. At the same time, the back-end server will periodically send a heartbeat to the front-end to monitor the connection status of the front-end user. After confirming that the front-end user is disconnected, log out the user management information and close the connection channel; 3. When an alarm event is reported on the AP device, and the alarm module of the cloud AC receives the alarm event, it generates alarm details according to business rules, and records the relevant alarm events. The information is pushed to the STOMP message middleware, and the STOMP message middleware regularly pushes the latest alarm information to the background server.

The retrieval unit 304 uses the background server to obtain the alarm information from the message middleware, and searches for the device information corresponding to the alarm information in the registered user management information according to the alarm information. Specifically, the retrieval unit 304 uses the background server to obtain the latest alarm information from the STOMP middleware. For example, the background server can be used to obtain the alarm information within three minutes from the STOMP middleware every three minutes, and then extract the corresponding alarm information from the alarm information. According to the device information of the device information, the registered user management information is searched for whether there is the device number and its corresponding user information.

The second push unit 305 uses the background server to send the alarm information to the front end of the corresponding user through the WebSocket protocol when the retrieval result of the retrieval unit 304 is to find the user corresponding to the device corresponding to the alarm information. That is to say, when the retrieval unit 304 finds the user information corresponding to the device number in the registered user management information according to the device number of the device information, the second push unit 305 uses the background server to send the alarm information through the WebSocket protocol. Sent to the front-end page of the corresponding user.
