Research Of Mobile Agent In Distribute E-Commerce Framework

The 21st century is informational century. With the network technology developed, the information revolution affecting our learning, working and all aspects of our normal life. E-commerce brought us a more convenient life, we can enjoy the fun of shopping when we are at home, and more and more people today have chosen this new way online shopping to meet their own needs.As nowadays E-commence becoming more and more complicated, traditional centralized E-commence system can not satisfy people's requirements, thus, distributed E-commerce system came into being. Because of distributed e-commerce systems' distributed properties, there are some problems in distributed e-commerce systems. The theory of Agent which was proposed at the beginning of 90s can solve the problem. The technology of mobile agent has a wide application prospect. At the beginning of the theory was proposed, it's intelligence, distribution and mobility characteristics attracted great attention of international experts and scholars most of who devote into the research of it and a great many achievements were developed. However, these achievements are mostly confined to theoretical research, and a small portion in the practical application of e-commerce is limited to the traditional centralized system of e-commerce framework. Therefore, how to introduce the mobile agent technology to the framework of the distributed e-commerce system framework is on the hot spots. And the study of this thesis is from this.This thesis studied theoretical knowledge in detail at first, contrasted the traditional centralized framework for electronic commerce, analysed the present structure of the distributed framework for electronic commerce. Then presented a detailed studied about basic concept, basic characteristics, structure and distribute computing characteristics of Mobile Agent technology, then presented a detailed research of the existing IBM's platform Aglet. Finally proposed a Distributed E-commerce framework which was based on Mobile Agent, and then using Object Oriented Analysis (OOA) to design the system. This thesis focuses on several key technologies of realization the framework. Do a lot of work especially the agent's migration, the implementation of B/S mode, aspect of learning side of the personality, intelligent search and filter protection agent from attacks of malicious mainframe.
