Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is obvious that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In the description of the present invention, it should be noted that, unless explicitly stated or limited otherwise, the term "configuration" is to be interpreted broadly, and may be, for example, addition, modification, or deletion; the term "management" is to be understood broadly, for example, it may be modification, deployment, creation, deletion, query, or derivation; the specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.
At present, with the rapid increase of the number of network element devices to massive devices and the increasing increase of the alarm number of network element devices to massive alarm data, with the diversified development of monitoring protocols inside network element devices and the increasingly complex equipment alarm processing services, a more efficient automatic alarm information management means is urgently needed to adapt to the change. In the prior art, either the requirements of high performance and dynamic expansion of the alarm management of mass devices cannot be met, or the self-adaptation requirements of monitoring protocols inside different network element devices cannot be met, or the complexity requirement of the alarm processing service cannot be met. In order to solve the above problems, in this embodiment, an alarm information management system is established based on a micro service architecture, and protocol self-adaptation is performed on communication protocol frames sent by each network element device in a south-oriented interface service, so that self-adaptation of monitoring protocols inside different network element devices can be achieved, and the alarm information management system based on the micro service architecture has the characteristics of clouding, dynamic expansion and high reliability, and can achieve self-adaptive expansion of the alarm information management system and a rapid management mechanism of alarm information.
The alarm information management system of the present invention is described below with reference to fig. 1, and the system includes: the system comprises network element equipment 1, a southbound interface service 2 and an alarm management service 3; the network element device 1 is configured to send a communication protocol frame to the southbound interface service 2;

The types of the gateway 7, the registration discovery, the message communication, the cache and the database can be set according to actual requirements, such as a Zuul gateway, a Zookeeper registration discovery, a RabbitMQ message communication, a Redis cache and an Oracle database.
The Zuul gateway is configured to provide a unified REST API (Application Programming Interface, presentation layer state transformation) call, and implement communication between the front-end microservices and the back-end microservices.
The Zookeeper registration discovery is used for registration and discovery when each back-end micro-service in the alarm information management system is initialized, such as other back-end micro-services like the southbound interface service 2 and the alarm management service.
RabbitMQ message communication is used for realizing interface message interaction among all back-end micro services, such as southbound interface service 2 and alarm management service 3; between the alarm management service 3 and the alarm policy service 4, and between the alarm management service and the northbound interface service 9.
The Redis cache is used for caching basic data of the Oracle database so as to improve the processing efficiency, and can be used for caching configuration information by each server. For example, the south-oriented interface service can perform protocol self-adaptation and group de-framing processing, the alarm management service 3 can cache configuration information, and the alarm policy service can cache mapping relationships.
