Abstract:

 The initial phase in a content distribution (file sharing) scenario
 is a delicate phase due to the lack of global knowledge and the
 dynamics of the overlay. An unwise distribution of the pieces in this
 phase can cause delays in reaching steady state, thus increasing file
 download times. We devise a scheduling algorithm at the seed (source
 peer with full content), based on a proportional fair approach, and
 we implement it on a real file sharing client [1]. In dynamic
 overlays, our solution improves up to 25% the average downloading
 time of a standard protocol ala BitTorrent
