To distribute video and audio data in real-time streaming mode, both CDN (Content Distributed Network) based and peer-to-peer based architectures have been proposed. However, each architecture has its limitations. CDN servers are expensive to deploy and maintain. The storage space and out-bound bandwidth allocated to each media file are limited and incur a cost. Current solutions to lowering such cost usually compromise the media quality delivered. On the other hand, a peer-to-peer architecture needs a sufficient number of 'Seed' supplying peers to 'Jumpstart' the system. Compared with a CDN server, a peer offers very low out-bound bandwidth. Furthermore, it is not clear how to fairly determine the contribution of each supplying peer.
