Based On The Research And Design Of Distributed E-business Model Of Cable Broadband Network Message Center

With the development of CATV technology, the CATV network has become the new kind of wide band. The applications based on CATV technology is becoming more and more recognized and attended. For example: the CA system based on CATV, the CATV increment service system based on bidirectional HFC. On the basis of a special-endowed network program of Yunnan Technology Bureau-The Interact Open Service Platform of CATV, this paper is a part production of the distributed e-business TV supermarket using J2EE technology based on CATV network.The research methods applied in the paper are as follows:First: To analyze the actuality of the current CATV technologies, and to discuss its' future and develop tendency. Second: To research the current e-business model, and to discuss the e-business model that fit for CATV network. Third: To compare synthetically with the current technologies of program development, and take the J2EE technology as our basic technology of program development. Forth: According the feature of CATV network, to develop the TV supermarket that can run on the CATV network.The emphasis of this paper is to research the communication technology between platforms of distributed system. The core technology is JMS in J2EE. This paper implemented the communication between platforms in different physical positions and data sharing using JMS successfully.Three main research results of the paper are as follows:First: Implemented the JMS message transfer between different platforms which is independent of the code, but managed by container.Second: Implemented the directed data exchange between RDBMS and XML files using XML-DBMS, which decrease the coding load and the system spending.Third: Combined the transaction and security mechanism in J2EE, implemented the message transfer reliably and securely.The paper not only provides a new thought of information transfer between distributed systems, but also developed the system that has practicability. The mechanism of Message Bridge and XML-DBMS technology has some referenced value to develop the distributed systems and has innovation and practicability.
