In this paper we propose a novel peer-to-peer filelocation system, BYPASS, to enhance the distributed filelookup time in DHT-based P2P systems. BYPASSconstructs a secondary overlay in which file locationinformation is distributed considering heterogeneity ofpeer capabilities and network proximity between requestsand results. The secondary overlay in BYPASS allows onlyhigh-capability peers to participate in the system-wide filelookup and takes advantage of physical network proximitybased on the Autonomous System (AS) network topology.We evaluate effectiveness of BYPASS using a set of large-scalesimulations. The results show that BYPASS cansignificantly reduce file lookup latency at the cost ofadditional, yet acceptable storage and network resources.
