Boosting content delivery with BitTorrent in online cloud storage services

In classic storage services, the transfer protocol used is usually HTTP. This means that all download requests are handled by a central server which sends the requested files in a single stream. But, such transfer is limited by the narrowest network condition along the way, or by the server being overloaded by requests from many clients. In this context, a number of studies have tried to combine BitTorrent content distribution technologies with Cloud environments. In fact, the efficiency of the BitTorrent protocol makes it especially suitable for massive content distribution while reducing bandwidth costs in the Cloud.
