The Research And Application Of The Remote Seamless Migration Based On The Web-server

The research of the seamleass migration is always a hot issue of the mobile computing technology. Due to the object the seamless migration involved is very more, and the spcace of the application is widely. So how to make the migration more effective for a variety of different object has become a problem. In addition, with the development of wireless network, the span of the object migration becomes wider and wider. With the continuing escalation of mobile terminal equipment, so the migration object in the presentation of different systems usually has a certain degree of heterogeneity. Because these problem, the migration technology of LAN appears the defect that the time of migration is too long and it doesn't support heterogeneous systems.With the development of mobile communication, mobile terminals of remote technical support beceme more and more advanced. In particular, with 3G terminals and 3G networks began to spread, the mobile terminals can browse the web page through http web browser. For this reason, the article analyse the method of connection based on the browser. On the base of transmission method of different object on Web Server, it proposed the use of browser-based server push technology to persistent http-connection. And the author also takes the migration object in the third-party servers, overcomes the shortcomings of LAN migration and achieves the seamless migration of long-range multi-media and file objects.The LAN mode of migration can become more effective among the local area network. But among different sytems, the migration technology must to develop different client. With the browser as terminal method, it is an effective long-range migration to avoid to develop the application of heterogeneous systems for client. Author proved that the browser-based server push approach to more efficient use of wireless networks throuth the experiment.
