Realization And Security Study On IPv6-Based Mutimedia Communication System

With the rapid development of Internet in recent years, The traditional data transmission can not meet the requirement of us no longer. The operation of multimedia transmission is more and more widespread. However, Network Security is always an important topic in IP network. It is significant to assuring the multimedia transmit security in network by all kinds of technology of network security.In this paper, we introduce H.323 protocol on the technology of multimedia transmission and IPSec protocol on basic theory of network security. We also realize an IPv6 multimedia communicating system, after comparing two methods which improve the security of the system.We choose a better one and build a security model to protect the security of the system. At last, we give a test on it.
