Realization Of Multimedia Short Messaging System Based On Tcp / Ip Network Testing Tools

In this paper, we discuss the general architecture and framework, information flow of the MMS system and provide a real testing system over TCP/IP network for the MMS system. The MMS system contains MMSC, MMDB, Operating Center, Testing Tools and the NetWork. In this paper ,We discuss the theory of Windows Sockets and Network Programming?Programming with Multithreading, The MD5 Message-Digest Algorithm and the method of the develpoment of the testing system., including some explanations of key technology. We put forward a design plan of this system and realized it on VC. Finally, all of the work in this thesis is summed up. The future research of this system is prospected.
