ABSTRACT

Recently the ratio of the Internet traffic generated by video streaming applications including video-on-demand (VOD) is getting higher and higher, while P2P-based naive content distribution has been themain source of the Internet traffic in the past. As a result, the paradigmof cooperatively distributed systems (e.g., P2P) is changing to support streaming applications. Most P2P assisted approaches for video streaming today are based on BitTorrent thanks to its simplicity of implementation and easy adaptability. They, however, have immanent vulnerability to free-riding inherited fromBitTorrent, which inevitably hurts their performance under limited systemresources with free-riding. This paper studies the weakness to free-riding of existing BitTorrent-based video streaming applications and investigates the adaptability of T-Chain (which was originally designed to prevent free-riding in cooperatively distributed systems) to video streaming applications. Our experiment results showthat the video streaming approach based on T-Chain outperformsmost existing BitTorrent-based ones by 60% on average under limited system resources with free-riding.
