Overlay Topology Matching in P2P Systems
نویسندگان
چکیده
The emerging peer-to-peer (P2P) model has gained significant attention due to its many unique features in supporting file sharing among a huge number of networked users. However, the mechanism of peers randomly choosing logical neighbors without any knowledge about underlying physical topology can cause a serious topology mismatching between the P2P overlay network and the physical underlying network. Adaptive overlay topology optimization and location-aware topology matching are two techniques aiming at alleviating the mismatching problem and reducing the unnecessary traffic and average query response time of unstructured P2P systems while still retaining the search scope. In this paper we compare the performance of these two approaches through simulation studies.

Can Heterogeneity Make Gnutella Scalable?
Even though recent research has identified many different uses for peer-to-peer (P2P) architectures, file sharing remains the dominant (by far) P2P application on the Internet. Despite various legal problems, the number of users participating in these file-sharing systems, and number of files transferred, continues to grow at a remarkable pace. Filesharing applications are thus becoming an incr...
متن کاملA Mathematical Foundation for Topology Awareness of P2P Overlay Networks
In peer-to-peer (P2P) overlay networks, the mechanism of a peer randomly joining and leaving a network, causes a topology mismatch between the overlay and the underlying physical topology. This causes a large volume of redundant traffic in the underlying physical network as well as an extra delay in message delivery in the overlay network. Topology mismatch occurs because overlay networks are n...

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 va...

Despite recent excitement generated by the peer-to-peer (P2P) paradigm and the surprisingly rapid deployment of some P2P applications, there are few quantitative evaluations of P2P systems behavior. The open architecture, achieved scale, and self-organizing structure of the Gnutella network make it an interesting P2P architecture to study. Like most other P2P applications, Gnutella builds, at t...
