Stable Transmission Of Streaming Media In The Ip Network

Now, we use the protocol IPv4. But Nowadays Internet is growing quickly. So, the next generation IP protocol was brought up in 1992. A new capability is added to enable the labeling of packets belonging to particular traffic "flows" for which the sender requests special handling, such as non-default quality of service or "real-time" service. The technology of stream media provides end-to-end delivery services in IP network with real-time characteristics, such as interactive audio and video. Applications typically run RTP/RTCP protocol on top of UDP. It is one of the focus researches, especially in IPv6. This article illustrates the framework of stream media in IPv4; include the basic theory and disadvantage. It is emphasis the important of time factor for QoS; and introduction the improvement of behavior in IPv6, especially in real time network. It introduce the applications of label exchange in IPv4 networks, such as MPLS; and researches the improvement of the related protocol based on the "real-time" service; specially the "flow"application in IPv6 networks.
