SODA: Towards a framework for self optimization via demand adaptation in Peer-to-Peer networks

Abstract

Peer-to-Peer (P2P) applications have been consuming an increasingly significant fraction of Internet bandwidth. They are becoming a financial burden to Internet Service Providers (ISPs), creating hot spots in the Internet, and causing potential performance degradation to other applications. As a result, there has been increasing tensions between P2P applications and network service providers. In this paper, we propose a framework called SODA for P2P applications to be self-adaptive and optimize their demands in order to more efficiently utilize network resources. Through preliminary experiments using two representative P2P applications, we demonstrate that SODA can effectively reduce bandwidth consumption by adapting the demands among peers. ? 2009 IEEE.EI
