Embodiment Construction

[0028] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0029] In the embodiment of the present invention, a workflow language is used to describe the business process of a combined service, and a business process of a combined service can correspond to a Workflow Network (WFN) model, that is, each business process can be expressed as WFN=(P, T, F, i, o, M 0 ). Among them, P represents the set of pla...

Abstract

The invention provides a self-adaptive combined service optimization method and a device thereof. The method comprises the following steps: acquiring a target change and a target changing path in the business flow of combined service according to the history of execution records of the combined service, wherein the target change is a change influencing decline of availability indicators, and the target changing path is a changing path with the highest execution frequency; intercepting a basic change sequence of the target change in the target changing path; expanding the basic change sequenceto obtain a redundant path according to the selection relationship and the concurrency relation of changes in the business flow; and adding the redundant path into the business flow. Due the evolution strategy of redundant processing in the technical scheme, the invention makes the evolution logic and the business flow logic independent of each other, thereby not only ensuring the correctness of the business flow without influencing the execution of the original business flow, but also reducing the unavailability probability through the redundant processing, and also improving the availability of the whole combined service.

Description

technical field [0001] Embodiments of the present invention relate to composite service evolution technology, and in particular to an adaptive composite service optimization method and device. Background technique [0002] With the wide application of the Internet (Internet) and the rapid development of network technology, Service Oriented Architecture (SOA) as a new networked software application model has been widely accepted by industry and academia. . The so-called service, that is, a software entity capable of executing a business logic, can be provided by the network side. [0003] In particular, as an important technology to realize SOA, Web service has greatly promoted the application of SOA in e-commerce, finance, telecommunications and other fields. In practical applications, a single Web service has limited functions and is often difficult to meet complex business needs. Therefore, service composition has become the main method of networked software development....
