Abstract
With the growth of multimedia devices and applications, we have more and morevailable media data distributed in computers in a house or even a building, so weeed an efcient way to access and integrate those data. In this thesis, we propose tose a P2P network architecture for multimedia streaming. In the P2P network, every-ne can contribute his own resources such as bandwidth and storage capacity. Thus,e can integrate the multimedia data among a community. However, the resourcesn a P2P network are time-varying. To guarantee the streaming quality, we design mechanism, Rate Adaption Bandwidth Allocation, to manage resources among theodes in the system. Rate Adaption Bandwidth Allocation performs three main func-ions: (1) selecting reliable nodes for incoming multimedia streaming; (2) schedulinghe chunk requests to meet timing constraints of video playback; (3) generating theandwidth allocation for nodes to reserve bandwidths. We implement Rate Adaptionandwidth Allocation in a real-world P2P system. We evaluate the performance ofate Adaption Bandwidth Allocation and, and discuss lessons learned from our expe-ience with respect to the practicality and further optimization of our system.
