Research And Implementation Of Mobile Agent System Based On CSCD In P2P Network

In the era of wide application of Internet, users require broader and more universal information resources sharing and transacting. With the development of the technology of computer network, users depend on network more and more, and more attention is focused on how to utilize rich and isomerous distributed resources. Researchers explored to constitute a reliable and high efficiency cooperative working environment. Nowadays the research of CSCW has become a hot research field.In the thesis, the possibility of application of mobile agent technology into the research of implementing AutoCAD cooperative design based on CSCW technology in the Peer-to-Peer network environment is discussed. Mobile agent technology is the outcome of the combination of distributed computing and artificial intelligence, which is quite different from traditional Client/Server model. It provides a new way to develop network application in the inferior network which has narrow bandwidth and high-frequency congestion.Utilizing mobile agent technology and applying it to network applications needs the support and management of a mobile agent system(MAS).It can also be called as mobile agent platform. So in the paper, we design and implement a mobile agent system which is called Peerlet. It is adaptable to our project"AutoCAD cooperative design in the Peer-to-Peer network". The design is based on the research of the status quo of available MAS and the main architechture and implementation technology. Peerlet is customized to keep to the general inter-operation standard drafts and integration standard drafts of the MAS. The implementation of Peerlet is to be open, convenient and flexible for the upper application development.OOP method is adopted in all the phases of development. The programming language is Java, which has many wonderful characteristics that benefit for the implementation of Peerlet. The paper first introduced the strategy and key technologies of each module in detail, secondly the mechanism of the agent migration is anatomized. Then we put Peerlet into the application of the function module distribution part of our project to testify it.In the end of the thesis, we do some further research of applying mobile agent technology into the procedure of cooperative design and propose a frame module of multi-agent based AutoCAD cooperative design system, which benefits for the future research job.
