Without assuming any knowledge of the underlying physical topology, the conventional P2P mechanisms are designed to randomly choose logical neighbors, causing a serious topology mismatch problem between the P2P overlay network and the underlying physical network. This mismatch problem incurs a great stress in the Internet infrastructure and adversely restraints the performance gains from the various search or routing techniques. In order to alleviate the mismatch problem, reduce the unnecessary traffic and response time, we propose two schemes, namely, location-aware topology matching (LTM) and scalable bipartite overlay (SBO) techniques. Both LTM and SBO achieve the above goals without bringing any noticeable extra overheads. More-over, both techniques are scalable because the P2P over-lay networks are constructed in a fully distributed manner where global knowledge of the network is not necessary. This paper demonstrates the effectiveness of LTM and SBO, and compares the performance of these two approaches through simulation studies.
