Sequence QoS-driven service integration method

Abstract

The invention discloses a sequence QoS (Quality of Service)-driven service integration method, which comprises the following steps: presetting a sequence combination flow chart, and selecting QoS attribute characteristics; processing the QoS attribute characteristics to obtain an initial vector CQoS of the service sequence sc, normalizing the initial vector CQoS to obtain a standardized vector CQoS ', and further calculating a service score Score CQoS'; utilizing Skyline calculation to extract a data object subset that is not dominated by any other candidate service object from each candidateservice object database corresponding to a task node in a preset sequence combination flow chart, and taking the data object subset as an initial search space for solving an ant colony algorithm; andsolving an allocation scheme corresponding to the optimal solution in the initial search space according to an ant colony algorithm. According to the method, the problems of data flooding and user preference are solved, and the efficiency of the integration process and the service quality of the service sequence are improved.

Description

technical field [0001] The invention relates to the technical field of service integration, in particular to a sequential QoS-driven service integration method. Background technique [0002] At present, more and more enterprises, organizations or individuals publish their physical resources to the Internet in the form of services. Service providers virtualize service resources according to business process division and build independent service modules. These modules often appear in the form of applications or APIs, and can be deployed, run and managed independently in the environment. Users only need to call services with corresponding functions through lightweight application software, interfaces or API (Application Programming Interface). However, due to the limited service functions provided by service providers, a single service may not be able to meet the functional requirements of users in many cases. The service has a good quality of service (Quality of Service, Q...

AI Technical Summary

Problems solved by technology

However, the difference with the atomic service is that the service quality of the service sequence cannot directly consider and directly process the service quality of each atomic service participating in its composition

First of all, the data "flooding" problem and user preference problem caused by the different operation units of each characteristic attribute of service quality have not been given a complete solution. The efficiency and service quality of the integration process is not satisfactory
