Fast scheduling on P2P streaming overlay
Jiaming Li, Chai Kiat Yeo, Bu‐Sung Lee · 2008
Peer-to-Peer architecture is widely applied in large scale distributed applications. For streaming applications, latency is one of the most important metrics which affect user experience. However, network dynamics such as congestion and bandwidth fluctuation cause instability in the peer overlay and increase peer latency. To avoid wasting network resources on overlay redirection, we introduce our scheduling algorithm [6] into the peers on the overlay to distribute most important packets to the descendant peers first. We also alter Maximum Bandwidth Sum Tree overlay construction scheme [4] to cater for streaming application and investigate our scheduling algorithm in such an environment. Performance results show the improvement in terms of latency and data arrival ratio before the expiration time.
