SPANC : optimizing scheduling delay for peer-to-peer live streaming

Abstract

In peer-to-peer (P2P) live streaming using unstructured mesh, packet scheduling is an important factor on overall playback delay. In this thesis, we propose and optimize a scheduling algorithm to minimize scheduling delay. To achieve low delay, our scheduling is predominantly push in nature, and the schedule needs to be changed only upon significant change in network states due to, for examples, bandwidth change or parent churns. Our scheme, termed SPANC (Substream Pushing and Network Coding), pushes video packets in substreams and recovers packet loss using network coding....[ Read more ]
