Abstract

The invention discloses a service combination method based on the service quality under an service oriented architecture (SOA) in a network system, comprising the following steps after saving distributed combination mode data in a computer memory: reading a distributed combination mode description file; determining a candidate web service resource pool matched in function; performing statistical process; building a statistical interval representation; discretizing each continuous quality index statistical interval; performing a local heuristic selection to each distributed computation node under the limitation of the initial mass; obtaining a service representation under the mass limitation, and converting the service combination problem under the SOA into an equivalent MIP problem by using the service representation obtained by each distributed computation node; and obtaining an optimal service combination scheme by solving the MIP problem based on the integer programming technology.In the invention, the optimal selection process of the service combination under the entire SOA is completely realized by the computer automatically, thereby enhancing the automation and the operation efficiency of the service combination.

Description

technical field

[0001] The present invention relates to a heuristic service combination method based on service quality under SOA (Service-Oriented Architecture, service-oriented architecture), especially suitable for portable computing devices connected to the network in a distributed environment, and specific services for users Quality requirements, and quickly select the optimal service combination plan to meet the real-time response requirements of users. Background technique

[0002] Under the SOA architecture, service objects and organizational entities described on different computing nodes need to interact with each other in information, data, and resources to complete a distributed composite business process. When executing this business process, it is necessary to instantiate the service objects and organizational entities on the distributed computing nodes—that is, to select the most suitable combination scheme from the service objects and organizational entities ...
