Optimizations for Locality-Aware Structured Peer-to-Peer Overlays
نویسندگان
چکیده
We present several optimizations aimed at improving the object location performance of locality-aware structured peer-to-peer overlays. We present simulation results that demonstrate the effectiveness of these optimizations in Tapestry, and discuss their usage of the overall storage resources of the system.

Locality in structured peer-to-peer networks
Distributed hash tables (DHTs), used in a number of structured peer-to-peer (P2P) systems provide efficient mechanisms for resource placement and location. A key distinguishing feature of current DHT systems, such as Chord, Pastry, CAN and Tapestry, is the way they handle locality in the underlying network. Topology-based node identifier assignment, proximity routing, and proximity neighbor sel...
متن کاملHybrid Overlay Structure Based on Random Walks
Application-level multicast on structured overlays often suffer several drawbacks: 1) The regularity of the architecture makes it difficult to adapt to topology changes; 2) the uniformity of the protocol generally does not consider node heterogeneity. It would be ideal to combine the scalability of these overlays with the flexibility of an unstructured topology. In this paper, we propose a loca...

Distributed hash tables (DHTs), used in a number of structured peer-to-peer systems provide efficient mechanisms for resource location. A key distinguishing feature of current DHT systems like Chord [15], Pastry [12], and Tapestry [19] is the way they handle locality in the underlying network.

متن کاملProviding Administrative Control and Autonomy in Structured Peer-to-Peer Overlays
Structured peer-to-peer (p2p) overlay networks provide a decentralized, self-organizing substrate for distributed applications and support powerful abstractions such as distributed hash tables (DHTs) and group communication. However, in most of these systems, lack of control over key placement and routing paths raises concerns over autonomy, administrative control and accountability of particip...
متن کاملAnycast in Locality-Aware Peer-to-Peer Overlay Networks
This paper advocates implementing anycast in peer-to-peer (p2p) overlay networks. We argue that anycast in p2p overlays (exemplified by Pastry, Tapestry, Chord, CAN) combines the advantages of IP anycast and existing application-layer anycast services. We show that anycast can leverage the locality-awareness embedded in existing p2p overlays. The locality-awareness of the p2p routing substrates...
