Congestion-Distortion Optimized Peer-to-Peer Video Streaming

Category: Software and Web Development, Networking and Communications

Overview In live peer-to-peer streaming, a video stream is transmitted to a large population of viewers, through the use of the uplink bandwidth of participating peers. This approach overcomes the cost of large-scale deployment of such services. An essential problem of this type of system is to limit the incurred congestion. In particular, overwhelming the uplink of some peers would create a large increase in the latency of the system and make this application less compelling. In this work the paper focuses on limiting the congestion in a peer-to-peer network where multiple multicast trees are used to distribute video to a large set of receivers. The paper presents the idea of congestion-distortion optimized streaming which aims at maximizing decoded video quality while limiting network congestion.
