| dc.description.abstract | Nowadays, with development of broadband networks and multimedia, most people are used to watch internet videos which they are interested. In order to provide multimedia services from one source to a huge number of users, many developers of multimedia applications may implement a large-scale streaming (i.e., multimedia traffic) system. However, such a system would encounter many difficult issues such as the scalability and the quality of the service.
Taking the scalability and the robustness of the system into consideration, many streaming systems are developed and implemented on the basis of P2P overlay network instead of the traditional client-server streaming system. The P2P streaming system distributes the loading from the server to every participative peer, and every peer in the P2P streaming system interconnects with each other to contribute and consume the resources. Hence, the P2P streaming system is more appropriate to provide the streaming services for a large number of users than the other system.
With the purpose of disseminating the live multimedia to a large number of users, we implement a live multimedia streaming system which runs on an embedded system based on the GRAPES library, which is an open source providing an efficient environment for developing a P2P streaming system.
In this thesis, we present a P2P streaming system based on the GRAPES library for multimedia streaming. By using the benefits of the GRAPES library, the implemented of the P2P streaming system is modularized. Furthermore, due to our requirements and considerations, we modify the Network Helper module to support TCP protocol. We describe the key designing issues of topology manager protocol in detail, including the message formats, the procedures and mechanisms of the topology manager, important parameters, and the visible monitor system.
