Method for dynamically building marine application service chain

Abstract

The invention discloses a method for dynamically building and realizing a marine application in a dynamic service chain manner. The method comprises the steps: 1, abstracting atomic service, wherein a normalized atomic service interface is confirmed; 2, abstracting service chain model elements, wherein a visualized representation form of the basic elements of the service chain, as well as a description method, a constraint and the like, is defined; 3, creating a service chain, wherein a service chain model aiming to a specific marine application is formed based on a visualized operation interface; 4, validating the service chain, wherein the validity and logicality of the marine application service chain created by a user are validated; and 5, managing the service chain, wherein monitoring and management are carried out over the forming and implementation sequence of the service chain, and over the state of each atomic service of the service chain. The method provided by the invention is capable of visually and quickly realizing the novel marine application requirement, and has the advantages that what you see is what you get, and flexible and dynamic performances are provided.

Description

technical field [0001] The invention relates to the field of dynamic creation and application of service chains, and is a method for realizing dynamic construction and realization of marine applications in the form of dynamic service chains. Background technique [0002] In recent years, the idea of ​​SOA and WEB service technology have achieved great development and wide application in the practice of informationization. On the one hand, researchers continue to introduce new service-oriented computing theories, methods, and models. Major academic groups and standardization organizations in the industry, such as OASIS and W3C, have also set up service-oriented computing research groups to continuously introduce SOA-related technical standards. On the other hand, in the industrial world, major IT giants around the world have launched their own service-oriented application platforms, expressing that they will fully support SOA, and most enterprises have also adopted SOA archit...

Problems solved by technology

Although the A1-based service composition method has a high degree of automation, due to the nature of the composition is limited to accidental composition, the objects in the composition are generated at runtime, resulting in the possibility of many branches in the composition. Once the services involved in the service composition are aggregated When it becomes very large, the search process and reasoning process of service composition will become extremely difficult, and the response time that users are satisfied with cannot be obtained, and the complexity of the method is relatively high, which is relatively difficult to implement

[0006] Although the existing two types of service composition methods can realize the dynamic composition of services, the former is based on a clear business logic process and relies more on human participation, while the latter has a higher degree of automation , but due to the lack of necessary combination constraints, the hit rate of the combined results is low. Both methods have their own advantages and disadvantages, and there is a certain gap with the user's goal of dynamically building and realizing marine applications.
