Recent years have witnessed an explosion of online video sharing as a new killer Internet application. Yet, given limited network and server resources, user experience with existing video sharing sites are far from being satisfactory. To alleviate the bottleneck, peer-to-peer 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 peer-to-peer 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 peer-to-peer accelerating. PPVA was first released in May 2008 and has since been constantly updated. As of January 2010, it has attracted over 50 million distinct clients, with 48 million daily transactions. In this paper, we highlight the unique challenges in implementing such a platform, and discuss the PPVA solutions. We have also constantly monitored the service of PPVA since its deployment. The mass amount of traces collected enables us to thoroughly investigate its effectiveness and potential drawbacks, and provide valuable guidelines to its future development.
