Underlay awareness in P2P systems: Techniques and challenges

Abstract

Peer-to-peer (P2P) applications have recently attracted a large number of Internet users. Traditional P2P systems however, suffer from inefficiency due to lack of information from the underlay, i.e. the physical network. Although there is a plethora of research on underlay awareness, this aspect of P2P systems is still not clearly structured. In this paper, we provide a taxonomic survey that outlines the different steps for achieving underlay awareness. The main contribution of this paper is presenting a clear picture of what underlay awareness is and how it can be used to build next generation P2P systems. Impacts of underlay awareness and open research issues are also discussed.

Evaluation of a Topological Distance Algorithm for Construction of a P2P Multicast Hybrid Overlay Tree

“…The idea to use the network coordinates is based on considerations from [13], [14] and [15]. In contrast to the algorithms presented therein, we use in our approach two data structures: the search tree Ts for searching the nearest neighbour according the topological position in the network and the multicast tree T to connect hosts to a P2P overlay multicast network.…”

Peer-to-Peer Multicasting Inspired by Huffman Coding

“…A classification of approaches using locality awareness in P2P overlays can be found in [12] (a) awareness of the ISPs network, to which a peer is assigned to; (b) storage of some additional information on other peers, for example, when they serve as supernodes; (c) delay assessments; (d) geolocation information as a base for the peer node selection. Our research follows the third avenue; that is, we base on the latency measured by .…”

Enabling resilient P2P video streaming: survey and analysis

“…Network aspects are mainly costs of communication between different ASs and internet service providers (ISPs) [13]. Since P2P increases the inter-domain traffic and, therefore, creates large costs for ISPs, they might place restrictions on the traffic to limit the impact on their costs.…”

“…In [13] different approaches that can be used to achieve underlay awareness are investigated and classified according to collection and usage methods. Four different underlay parameters were identified, namely ISP-location, latency, geo-location, and peer resources.…”
