EUE principle of resource scheduling for live streaming systems underlying CDN-P2P hybrid architecture

Peer-to-peer live streaming offers plenty of live television programs for users, and has become one of the most popular Internet applications. However, some ubiquitous problems such as long startup delay and unsmooth playback seriously restrict the quality of service of live streaming, whereas deploying dedicated servers immoderately will suffer from excessive costs. In this paper, we introduce economical-underloaded-emergent (EUE) principle to instruct resource scheduling for live streaming systems based on CDN-P2P hybrid architecture. Complying with this principle, we differentiate peers’ chunk requests according to their playback deadline and propose a set of mechanisms to provide distinct service for diverse requests. The results of simulation experiment demonstrate that EUE principle effectively optimize system performance, and achieve the remarkable reduction of startup delay and increase of chunk arrival ratio.
