PPVA: A universal and transparent P2SP accelerator for online video sharing

To alleviate the server bandwidth cost of online video sharing services, p2p delivering has been suggested as an effective tool with success already seen in accelerating individual sites. The numerous video sharing sites existed however call for a universal solution that provides transparent p2p acceleration beyond ad hoc solutions. More importantly, only a universal platform can fully explore the aggregated video and client resources across sites, particular for identical videos replicated in diverse sites. To this end, we develop PPVA, a working platform for universal and transparent P2SP (peer to server and peer) accelerating. As of May 2011, it has attracted over 190 million distinct clients, with 78 million daily transactions. We will demonstrate the novel features, implementation, and also effectiveness of PPVA.
