Research On Internetware Evolution Model Of Service-Oriented Entity

The emergence and popularity of the Internet, computer software runtime environment is gradually beginning from a closed, static, controlled to an open, dynamic and changeable. How to achieve all kinds of network resource sharing and integration under open, dynamic and changeable environment has become one of the important challenges of computer software technology. Interntware is a new type of software in the future open coordination environment (such as Internet), it is built upon the coordination of the heterogeneous, autonomous software entities in the open coordination environment. The principal work of this paper is for the need of the Internetware, based on the basic theory, methods and technologies of the Internetware, as the starting point of resource sharing and integration under the open network environment, systematically analyzed and designed service-oriented entity of Internetware evolution model.Firstly, this paper reviews and analysis some typical Internetware models, summed up the advantages and disadvantages of each, and for shortcomings of these typical Internetware models, proposed the development of Internetware still needs coordination combination of model entity and dynamic evolution mechanisms to provide support. Learn from the modeling idea of these typical Internetware models, proposed using the new methods and strategies to construct Internetware evolution model based on service entity. Secondly, the detailed construct service-oriented entity of Internetware evolution model, the open coordination model as the basis model of the model, the service entity as model entities of the model, and designed trust measurement mechanism and link mechanism for the model. The model consists of sponsored layer, initially formed layer, filter layer, implementation layer, and in-depth analysis of each layer is to construct out of a specific implementation strategies. Finally, this paper designs dynamic evolution mechanism for the model, the dynamic evolution mechanism relies on built-in runtime structure to construct with independent encapsulation connection redirection algorithm, service entity migration algorithm, service updating algorithm, Combining the above algorithms construct the evolution strategy for the model, and by designing the detailed simulation experiment, detail analysis and validate the model of the rationality and validity. The work of this paper proposes concrete solution strategy to some key problems concerning the present Internetware development under the open network environment, which is of importance for the further theoretical research on cooperative combination and orderly evolution of open complex network environment service resources, as well as for solving the problem of network resource sharing and integration under open, dynamic and changeable environment.
