Embodiment Construction

[0036] Specific embodiments of the present invention will be described in detail below. It should be noted that the embodiments described here are for illustration only, and are not intended to limit the present invention.

[0037] The invention improves the prior success rate of service calling by actively selecting services, and improves the actual running success rate of service calling by passive error repair. figure 2 It is a schematic diagram of the fault-tolerant strategy flow of the present invention, wherein passive error repair is a strong guarantee for the successful operation of the fault-tolerant strategy, and active service selection is a guarantee for the powerful improvement of the efficiency and reliability of the fault-tolerant strategy. A fault-tolerant strategy that only selects a service plan cannot guarantee the reliability of service operation, and a fault-tolerant strategy that only has an error repair plan cannot guarantee the execution efficiency of ...

Abstract

The invention discloses an OSGi fault-tolerant strategy for service quality evaluation in a distributed environment. The invention adopts the combination of active screening service and passive error repair to achieve the purpose of fault tolerance. Before the service is called, the active screening service mode is selected. Call the target service to improve the success rate and operating efficiency of this service call. During the process of service invocation, the operating parameters of the service are collected through service detection and the error information of the service invocation is captured; when the error information is captured, the invocation process is repaired by using the error repair method to improve system stability, thereby passively ensuring the success of the service .

Description

technical field [0001] The invention belongs to the technical field of computer fault tolerance, and in particular relates to an OSGi fault tolerance strategy oriented to service quality evaluation in a distributed environment. Background technique [0002] Computer science is one of the fastest-growing disciplines in the 21st century and has the greatest impact on human life. As an important part of it, software engineering has also been paid more and more attention. With the rapid development of computer software technology in recent years, the component-based development model has gradually become the development trend in the field of software engineering. [0003] OSGi (open service gateway initiative) is a service-based component technology framework, which has attracted the attention of developers because of its features such as ease of use, lightweight, dynamic update, and component life cycle management. OSGi provides a dynamic, service-oriented construction model ...
