Proximity-Aware Superpeer Overlay Topologies

by Gian Paolo Jesi, Alberto Montresor, Ozalp Babaoglu - In Proc. of SelfMan'06, LNCS 3996 , 2006
"... Abstract — The concept of superpeer has been introduced to improve the performance of popular P2P applications. A superpeer is a “powerful ” node that acts as a server for a set of clients, and as an equal with respect to other superpeers. By exploiting heterogeneity, the superpeer paradigm can lead ..."

The main issues in constructing superpeer-based overlays are the selection of superpeers and the association between superpeers and clients. Generally, superpeers are either run voluntarily (without an explicit

1 Myconet: A Fungi-inspired Model for Superpeer-based Peer-to-Peer Overlay Topologies

by Paul L. Snyder, Rachel Greenstadt
"... Abstract—Unstructured peer-to-peer networks can be extremely flexible, but, because of size, complexity, and high variability in peers ’ capacity and reliability, it is a continuing challenge to build peer-to-peer systems that are resilient to failure and effectively manage their available resources ..."

We have drawn inspiration from the sophisticated, robust, root-like structures of fungal hyphae to design Myconet, an approach to superpeer overlay construction, which models regular peers as biomass, and superpeers as hyphae that attract and concentrate bio-mass, while maintaining strong inter

A super-peer based lookup in structured peer-to-peer systems

by Yingwu Zhu, Honghao Wang, Yiming Hu - in Proceedings of the 16th International Conference on Parallel and Distributed Computing Systems, PDCS’03
"... All existing lookup algorithms in structured peer-to-peer (P2P) systems assume that all peers are uni-form in resources (e.g., network bandwidth, storage and CPU). Messages are routed on the overlay net-work without considering the differences of capabilities among participating peers. However, the ..."

, the heterogene-ity observed in deployed P2P systems is quite extreme (e.g., with up to 3 orders of magnitude difference in bandwidth). The bottleneck caused by very limited capabilities of some peers therefore could lead to inef-ficiency of existing lookup algorithms. In this paper we propose a super-peer based

Semantic Overlay Clusters within Super-Peer Networks

by Alexander Löser, Felix Naumann, Wolf Siberski, Wolfgang Nejdl, Uwe Thaden - IN: PROCEEDINGS OF THE INTERNATIONAL WORKSHOP ON DATABASES, INFORMATION SYSTEMS AND PEER-TO-PEER COMPUTING, 2003 (DBISP2P 03). S , 2003
"... When joining information provider peers to a peer-to-peer network, an arbitrary distribution is sub-optimal. In fact, clustering peers by their characteristics, enhances search and integration significantly. Currently super-peer networks, such as the Edutella network, provide no sophisticated mea ..."

means for such a "semantic clustering" of peers. We introduce the concept of semantic overlay clusters (SOC) for super-peer networks enabling a controlled distribution of peers to clusters. In contrast to the recently announced semantic overlay network approach designed for flat, pure peer

A Robust Algorithm for the Membership Management of Super-peer Overlay

by Meirong Liu , Jiehan Zhou , Timo Koskela , Mika Ylianttila
"... Abstract. Peer-to-Peer technologies have been widely applied for multimedia applications. The super-peer based approach provides an efficient way to run applications by exploring nodes' heterogeneity. In P2P live video streaming, even though the number of stable nodes is small, they have signi ..."

significant impact on the performance of the network. Thus, we present a super-peer-based overlay design, where stable nodes are assigned as super-peers that organize client nodes. A gossip-based super-peer selection algorithm (GSPS) is proposed to identify the stable nodes to be chosen as super-peers

Push-Pull Two-layer Super-Peer based P2P Live Media Streaming

by unknown authors
"... Abstract: Peer-to-peer (P2P) file sharing has become increasingly popular, accounting for as much as 70 % of Internet traffic by some estimates. Recently, we have been witnessing the emergence of a new class of popular P2P applications, namely, P2P audio and video streaming. In this paper, we propos ..."

Our protocol, termed P2P Super-Peer based Unstructured Live Media Streaming (PALMS-SP), makes use of combination of push-pull scheduling methods to achieve high
