SOMO: Self-Organized Metadata Overlay for Resource Management in P2P DHT
نویسندگان
چکیده
In this paper, we first describe the concept of data overlay, which is a mechanism to implement arbitrary data structure on top of any structured P2P DHT. With this abstraction, we developed a highly scalable, efficient and robust infrastructure, called SOMO, to perform resource management for P2P DHT. It does so by gathering and disseminating system metadata in O(logN) time with a selforganizing and self-healing data overlay. Our preliminary results of using SOMO to balance routing traffic with node capacities in a prefix-based overlay have demonstrated the utility of data overlay as well as the potential of SOMO.

A Hierarchical Semantic Overlay for P2P Search
In this paper, we propose a hierarchical semantic overlay network for searching heterogeneous data over wide-area networks. In this system, data are represented as RDF triples based on ontologies. Peers that have the same semantics are organized into a semantic cluster, and the semantic clusters are self-organized into a one-dimensional ring space to form the toplevel semantic overlay network. ...
متن کاملRFC 7363 Self - Tuning DHT for RELOAD
REsource LOcation And Discovery (RELOAD) is a peer-to-peer (P2P) signaling protocol that provides an overlay network service. Peers in a RELOAD overlay network collectively run an overlay algorithm to organize the overlay and to store and retrieve data. This document describes how the default topology plugin of RELOAD can be extended to support self-tuning, that is, to adapt to changing operati...
متن کاملHierarchical architectures in structured peer-to-peer overlay networks
Distributed Hash Tables (DHT) are presently used in several large-scale systems in the Internet and envisaged as a key mechanism to provide identifier-locator separation for mobile hosts in Future Internet. Such P2P-based systems become increasingly complex serving popular social networking, resource sharing applications, and Internet-scale infrastructures. Hierarchy is a standard mechanism for...
متن کاملPeer-to-Peer Systems for Discovering Resources in a Dynamic Gridpdfauthor
The convergence of the Grid and Peer-to-Peer (P2P) worlds has led to many solutions that try to efficiently solve the problem of resource discovery on Grids. Some of these solutions are extensions of P2P DHT-based networks. We believe that these systems are not flexible enough when the indexed data are very dynamic, i.e., the values of the resource attributes change very frequently over time. T...
متن کاملImproving Community Management Performance with Two-level Hierarchical DHT Overlays
In this paper, we evaluate a P2P community management system that works on top of a DHT-based P2PSIP protocol implementation. The key idea in our system is to establish a separate DHT overlay network for each community, resulting in multiple small overlays that are subsets of the main overlay. The main DHT overlay is largely used for community and membership information discovery. The feasibili...
