The Application Research Of Real-time Info Transmission Using Multicast Over Sharing Networks

With the development of multi real-time Info transports, network has alreadychanged from special network for Info to sharing netwouks. How to realize real-timeInfo transports over IP becomes new question for network transports technology.Because traditional IP network does not supply multi real-time Info transports withgood service, new control means need to be researched to help TCP/IP protocolcomplete real-time transmission task of real-time data.This paper analyzes some issues of network protocol for supporting real-timetransports and discusses the real-time transport protocol(RTP) in concept, function,support real-time communication and realization.This thesis focuses on researchingnew transmission control means, in order that sharing networks can adapt to multreal-time Info transports needs and attempt to supply better quality of service for user.This paper realize real-time Info transports over sharing networks.
