An Enhanced Scalable Proximity Model

In this paper, an enhanced scalable proximity model is described. This work investigates the bandwidth estimation problem and it is impact on the quality of service of the file sharing application. The file transfer application over the TCP protocol is considered and it can be encountered in the emerging file sharing P2P applications or in the replicated Web server context. Since the impact of the bandwidth estimation is the main concern, the large TCP transfer due to its sensitivity to the parameter is considered. Thus considering the delay alone for proximity characterization is far from being optimal for large file transfer applications
