A Study Of Service Invocation In Internet Service Community

With the development of Web2.0, different types and styles of service were spread rapidly throughout the Internet, and a growing number of service providers are joining in the rank. It makes challenges to the management of service resources. Internet service community as a new kind of resource model in Internet environment becomes a new direction to the management of Internet services. Its domain feature is more suitable for building of business applications or processes for specific domains. It has become the first-choice technical solution to the management and selection of service resources in the Internet open computing platform.At present, most of service-oriented business process engines or application deployment environments only support single kind of resource type. Its runtime support to the real-time business applications or processes, which was built upon the different kinds of service resources in the service community, is not satisfied. Combined with the work had been done in the service community, the main work of this thesis are listed as follows.Firstly, this thesis discusses the origin of Internet services community, its composition, its storage management mechanism and distributed service community, and then makes some analysis on the problem related with invocation of service resource.And then, this thesis brings forward a service invocation framework based on invoke-type in order to resolve the problem about invocation of different kinds of service resources. So it can provide runtime support to the upper-business applications or business process. The framework provides a unified invoke interface, which shields the invocation details of service resources to the upper-application systems and makes the process engines and business application's runtime environment unnecessarily to take care of the invocation of service resources at runtime, which simplifies the complexity of design and implementation obviously.Finally, this thesis implemented a prototype of the service invocation framework, and it was applied and validated in the integration suite of VINCA Internet services.The results of the experiment showed that the service invocation framework based on invoke-type has good scalability and flexibility to different application environments, and markedly increases the invocation capacity of workflow engine and service-based business systems to different types of services resources, and provides good runtime support to upper-business applications and useful support to promotion and application of Internet service community simultaneously.
