Abstract


With the expansion of Internet and rapid growth of Internet users, the media streaming is becoming the mainly driving force for future broadband network applications. As a typical usage of media streaming, live streaming is very popular for it is realtime. P2P live streaming can provide higher network capabilities and has lower deployment cost by utilizing the resources of peers’, so is widely studied and used.In this thesis, a new live streaming protocol named Media Telecom Network (MTN) live streaming protocol is proposed, and based on NS2 network simulation platform, the protocol is implemented for analysis and evaluation. The thesis firstly introduces the MTN live streaming protocol and related algorithms. In MTN, the directory server is responsible for looking up partner nodes for peers, and streaming media data is distributed between peers in P2P manner. "Push and Pull" method is used for data transmission. Then the thesis discusses the simulation implementation and algorithms in detail, including the information management, routing algorithm of the directory server, and the synchronization mechanism of the media server, and the sub-flow strategy, partnership management and buffer management algorithms of the peers, as well as the the clean-up and restart mechanisms of the peer. Finally, through the simulation of more than five thousands peers, MTN live streaming protocol is evaluated to be with advantage of launching fast, good continuity and affording high rate video. At the same time, the backbone network traffic has dropped significantly due to the traffic localization strategy.Overall, this thesis provides a high reference value to the research and development of large-scale simulation on MTN live streaming protocol.
