Research On Trans-Regional Distributed E-Commerce System Architecture And Key Supporting Technology

With its rapid development, E-commerce has been a pillar in IT industry. But the architecture of today's e-commerce system is behind the trend of computer development. With deep research on P2P Computing, Mobile-Agent and Web Service, which have become hot spots in computer technology, and careful analysis of the existing shortcomings of the architecture of the present e-commerce system, a brand-new trans-regional distribution e-commerce system architecture is put forward and designed in this present dissertation. Different from the traditional e-commerce system, the non-centralized architecture makes full use of the advantages of new computer technology to distribute the e-commerce events and databases on several trans-regional servers so as to raise systematic reliability, expansibility, stability, and maintainability. Based on the existing commercial systematic facility and advanced technical platform , the system integrates multi-commercial activities of e-commerce under the loose-coupled service programs so that the trans-regional architecture of large scale distributed e-commerce system is formed. Finally, the New Mode of Trans-Regional Infinite Joining E-commerce based on the architecture has been proposed for the first time.The e-commerce system architecture and the key supporting technologies of the architecture are explored in this dissertation. There are some innovations in the following aspects.With Agent and P2P technologies as the cores, the open service architecture in agent-based P2P environment named OSA-ABP, is hereby proposed and designed, which includes five-layer structure model, multi-agent collaborative model and three-layer network model. The architecture resolved or improved some problems, such as cross-platform Multi-Agent communications, interface independence, resource acquisition with Agent participation, positioning and coordination tasks, as well as network congestion and P2P node failure. And it is able to carry out effective organization of the calculation and decomposition of tasks, to improve the utilization of high performance nodes and to enhance the nodes freedom and manageability. The Trans-Regional Distributed E-commerce Architecture based on OSA-ABP is also proposed and designed. The new architecture is applicable to the transaction modes of B2B and C2C and its prototype is implemented to prove the architecture availability and correctness. E-UDDI, mobile Agent migration strategy and message description of XML-based Multi-Agent communication are designed to enrich the theory and technical details of the architecture. From the initiation of business conduct, business resource found, local business resource publishing and business resource assessment, the prototype system of the architecture is designed and verified.With Web Service technology as the core, the Trans-Regional Distributed E-commerce System Architecture which is applicable to the three major traditional e-commerce transaction modes of B2C, B2B and C2C, is proposed and designed. The new concept of Customer-server to solve the problem of virtual image integration of marketplace is put forward. The problems of Single Sign On and the access bottleneck of the architecture are solved through using IP redirection server. The United Signature Scheme for supporting multi-safety communications and Web Service Composition Mode for meeting the demand of services in the architecture are designed in the dissertation. And the application example is designed to verify the rationality, feasibility and practicality of the architecture. Finally, the New Mode of Trans-Regional Infinite Joining E-commerce based on the Trans-Regional Distributed E-commerce System Architecture is proposed, which can be accepted to cover the three traditional transaction modes of B2C, B2B and C2C and to support expansion with low-cost anywhere.
