Abstract


In the Internet environment, was the growth of the geometrically as the number of Web services, in a lot of the uneven quality of the service, how to ensure that applications based on service-oriented architecture is always constituted by the quality of service has become the current must To resolve the problem. The quality of service reflects the Web services non-functional requirements, non-functional quality will be the sole criterion for customers to choose the services when a range of services can perform the same function. Traditional measurement model does not apply to service-oriented architecture field. This paper is a measure of service features in the application of service-oriented architecture. Followed by analysis services coupled four sides, the service reusability of components and services can be combined sub-attributes, and focuses on the flexibility of the service, scalability, agility and interoperability, and combine the Web The service features characteristic measure of a set of SOA services model. Service Coupling Metrics model has dependencies from the service point of view of service coupled Measurement and Analysis. The model not only takes into account the coupling of the service itself, but also integrates the degree of coupling between the services, the overall degree of coupling indicator of the degree of coupling of the required services and solutions portfolio of services reflects the coupling of the essence. The model can fully measure the impact of the coupling of services, the independence of the forecasting services and service changes. Service reusability measurement model reusability metrics atomic services. The model distinguishes atomic services function Universal degrees and business universal degrees, taking account of the module of the impact of reusability, and thus defines a service module indicators, and, through a combination of service business Universal degree and services modularity, reusability given service level index. The service composability measure model based on the relationship between the atomic service, a combination of service and atomic services to measure and analyze. The combination is in the implementation phase of the service due to the use of existing services, by combining Web service characteristics, redefine the service granularity, and the difference between the granularity of service parameters, and service interoperability indices. In this paper, service coupled, reusable design a prototype system and can be combined measurement model and measure the validity of the model is verified by experiment. Experimental data reflect the solutions in this article, can effectively measure service coupling, reusability and composability.
