Service management method based on service directory proxy servitization and scoreboard method

Abstract

The invention discloses a service management method based on service directory proxy servitization and a scoreboard method, which comprises the following steps of: deploying a service directory proxy service which can be accessed and used in each machine, and establishing access connection between the machine and a service directory by using the service directory proxy service; performing service registration, application registration and service addressing based on the established access connection; based on the established access connection, carrying out service information change notification by adopting a scoreboard method, wherein the service information change notification carried out by adopting the scoreboard method comprises the following steps: when an application or service accesses other services, a service directory in a machine where the application or service is located is utilized to act as the service to record access information; and the access information is sent to the service directory for storage, and service information reliable change notification is performed based on the access information stored in the service directory in combination with a reliable notification mechanism. According to the method, a large amount of query connection with the service directory can be avoided, and the query and change push pressure of the service directory is reduced.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to the reliability and usability design of a large-scale software system in a mobile environment, and more specifically to a service management method based on a service directory proxy service and a scoreboard method. Background technique [0002] At present, software in various fields is developing in the direction of service, especially for large-scale military information systems in mobile environments, software as a service faces more challenges in all aspects. In the context of software as a service, the access of applications to services and the access between services is a research focus. For large-scale software systems, it is often necessary to register metadata such as service addresses in the service directory first, and applications or other The service initiates access to the service directory by embedding the service directory proxy to obtain metadata such as the ad...

Problems solved by technology

At the same time, due to the existence of a large number of connections and network jitter in the mobile environment, it has a great impact on the availability and reliability of the entire software system

[0003] In existing large-scale software systems, each application and each service is embedded with a service directory agent, and the service directory agent will establish an access connection to the service directory. The service directory agent embedded in each application and each service usually Use the method of long polling or long connection to query the address change on the service directory. No matter whether the address is changed, the long polling or long connection will always exist. If there is a change, the change information will be returned. If there is no change, the no change signal will be returned periodically. And initiate a new query, which will cause great query pressure on the service directory in the large-scale software system in a mobile environment, affecting the performance of the software system

In addition to long connection / long polling, there is currently a method of broadcasting service instance change notifications through the service directory. At this time, applications and services will receive change notifications regardless of whether they need to access the changed service instance. This requires more network High, not suitable for large-scale software systems in mobile environments with unstable networks

Also, the service directory proxy embedded in each application and each service needs to have client-side load balancing capabilities, resulting in increased scale and support costs for applications and services

[0004] In addition, in a mobile environment, it is very easy to experience network jitter or even interruption. If each service is embedded with a service directory agent and establishes a connection with the service directory through a long connection or long polling method, in a mobile environment After the server network where the service directory is located is abnormal and restored, it is very easy for all clients to reconnect to the service directory at the same time, causing a connection storm and directly causing the service directory server to be abnormal
