Design And Development Of IP Mobile System In The Networks Of Campus

Along with the rapid development of information and network application, specially the rapid popularization of portable computer and motion computation technology, the demand on the application of technology enabling information to move or flow into the connection with Internet/Intranet whenever necessary called for in the enterprise environment has become extremely prominent and common. The inherent internet/Intranet connection mechanism has brought great limitation to prevent people from visisting and using the network information. The appearance of Mobile IP technology breaks through the former routined connection between the position and the communication facilities, which has made it possible to exchange information timely and conveniently. The combination of the communication means of the mobile communication and the Internet/Intranet information resources as to develope the mobile data service has become an important direction and hot topic for the development of current mobile communication industry and the information industry.It is by using the communication mechanism supported by this kind of mobile IP technology that the mobile MIP system of local area network provides the real time and mobile information communication service through the network.. This system solves the problem that in the Intranet based on IPv4 agreement, if the IP address prefix of the mobile communication pitch point has been changed, this host IP address has to be changed accordingly to meet the requirement of communication.This thesis carries on an introduction to the system theory and its key technology, and then the design to the three software entities contributing to the system, and finally the confirmation in the local area network based on the Linux service platform . Limited by the PC machine experiment environment based on which this research is being carried on, any possible further improvement shall be of widespread significance in its application in networks of enterprises and campus .
