Improving Throughput and Node Proximity of P2P Live Video Streaming Through Overlay Adaptation
Source: Trinity College Dublin
Due to the heterogeneity of the environment, in which hosts may have different bandwidth capacities and network distances between hosts vary, current mesh-based multicast protocols for video streaming over the Internet tend to inefficiently utilise the available bandwidth and often transfer large amounts of data between distant hosts. This limits system throughput, which results in reduced video quality, and imposes significant costs on Internet Service Providers (ISPs) caused by network traffic outside a provider's own network. This paper presents MeshTV, a mesh-based peer-to-peer (p2p) multicast protocol for streaming live video from a transmitter to numerous viewers.
