Design and Implementation of a Locality-Aware P2P System

Author(s): Luigi Ciminiera, Guido Marchetto, Marco Papa Manzillo, Vinicio Vercellone, Mario Ullio.


One of the most relevant problem for an Internet Service Provider is the large bandwidth usage on international links, mainly due to peer-to-peer applications adopted for file-sharing. The Collaborative Locality-aware Overlay SERvice (CLOSER) technology has been recently proposed to solve this issue by properly modifying the behavior of peer-to-peer application. The technology is also covered in two recent patent applications. This paper presents possible design guidelines to actually implement CLOSER in a DHT-based peer-to-peer system and describe a real implementation based on the popular aMule application.

Keywords: Peer-to-peer, File-sharing, traffic locality, DHT, ISPs, P2P system, CDN, ASN, IANA, biological peptides, CBQ, Criticality index, CSearchManager, CKademlia, CPrefs, CRoutingZone, CIndexed
