A Sound Mathematical Basis for Quality of Service Profiles in Web Service Discovery

چکیده
Standardisation of the description and delivery of distributed XML-based ‘web services’ has opened up a market, larger than any before, in ‘commercial off the shelf’ (COTS) software components. As a result, agreements are being reached on the assembly of systems from web services where the choreography if defined by workflow languages such as BPEL. With several potential implementations for many of the requirements within such a system, the need has never been greater to aid, through automation, the discovery process. Furthermore when many functional equivalents exist, it becomes much more important to discriminate between these on the basis of cost and performance. In this paper we correct and extend a framework for the application of such considerations within web service discovery for workflow-defined applications.

In general, Policy-based approaches play an important role in the management of web services, for instance, in the choice of semantic web service and quality of services (QoS) in particular. The present research work illustrates a procedure for the web service selection among functionality similar web services based on WS-Policy semantic matching.

متن کاملQoS-Based web service composition based on genetic algorithm
Quality of service (QoS) is an important issue in the design and management of web service composition. QoS in web services consists of various non-functional factors, such as execution cost, execution time, availability, successful execution rate, and security. In recent years, the number of available web services has proliferated, and then offered the same services increasingly. The same web ...
