An Efficient Fault Tolerant Approach to Resource Discovery in P2P Networks

چکیده
Current research into resource discovery in peer-topeer networks is largely focussed on the use of Distributed Hash Tables and multi-layered topologies. In this paper we present a resource discovery system capable of resolving keyword-value pair queries, based on a two-layered Chord ring architecture. We show how the base topology augmented with shortcuts between layers and selection of ring member nodes provides performance benefits and the potential for increased fault tolerance over other similar resource discovery systems.

A Taxonomy of Peer-to-Peer Based Complex Queries: a Grid perspective
Grid superscheduling requires support for efficient and scalable discovery of resources. Resource discovery activities involve searching for the appropriate resource types that match the user’s job requirements. To accomplish this goal, a resource discovery system that supports the desired look-up operation is mandatory. Various kinds of solutions to this problem have been suggested, including ...
متن کاملA Middleware for Job Distribution in Peer-to-Peer Networks
Recently, Peer-to-Peer (P2P) technology has become important in designing (desktop) grids for large-scale distributed computing over the Internet. We present a middleware for distributed computing based on Peer-to-Peer systems. When combining public-resource computation ideas with concepts of P2P networks, new challenges occur due to the lack of global knowledge as there is no central administr...
متن کاملHigh Performance Overlay File Distribution by Integrating Resource Discovery and Service Scheduling
Many existing studies in overlay networking have focused on resource discovery or server selection. This work studies the integrated performance of peer-to-peer (P2P) file sharing systems using location-aware resource discovery and service scheduling schemes. A novel file capacity amplification (FCA) model is first presented to capture the problem of the file distribution problem. Then two nove...

متن کاملFault-tolerant peer-to-peer search on small-world networks
This paper presents small world architecture for P2P networks (SWAN) for content discovery in multi-group P2P systems. A semi-structured P2P algorithm of SWAN is utilized to create and find long-range shortcuts toward remote peer groups. In SWAN, not every peer node needs to be connected to remote groups, but every peer node can easily find which peer nodes have external connections to a specif...
