Tiered service aggregation model under open network environment

Abstract

The invention discloses a tiered service aggregation method under the open network environment, which is a scheme for realizing the complex requirement of a user under the open network environment and for realizing the selection control of network resource or service. By aiming at the characteristics of the large scale, the dynamics and the isomerism of the open network environment, the tiered service aggregation method provides an information service five-layer aggregation method comprising an original service resource pool, a selected service resource pool, a relevant service resource pool, a multiattribute selection process and a relevant selection process; and the model is used for realizing the selection control scheme of the model. When the network is formed, the scheme is used for classifying service functions, relevance and the like provided by the user, resource pools of different tiers are built, and a tiered service aggregation decision mechanism based on the QoS is built. The service selection function based on QoS is expanded by the scheme, the dynamic characteristic and the unified interface characteristic of the selection control are added, and a brand-new mode is provided for researching the service selection mechanism under the open network environment.

Description

technical field [0001] The present invention is a scheme for realizing user's on-demand classification and selection control of service resources in an open, heterogeneous and complex network environment. Aiming at the dynamics, heterogeneity and increasing number of services in the open network environment, a service resource selection control model is proposed. Using this model to realize a layered service aggregation from bottom to top, to solve the increasingly complex problem of service selection process, belongs to the interdisciplinary field of information service, distributed computing, and computer software security technology. Background technique [0002] In the context of global economic integration and informatization progressing in depth, the integration and service-oriented development trend of information technology is changing the structure of the information industry. The information service industry has become the part of the information industry with the...

Problems solved by technology

Abstracting and encapsulating resources through services is one of the main means of resource virtualization, but the service-oriented architecture adopts the "service provider-centric" model, which easily leads to the difficulty of users discovering and subscribing to services as the number of services increases. Increase

[0004] Faced with an increasing number of different services in the network and the same service provided by different service providers, as a service requester, the process of making service selection becomes more and more complicated
