P2P traffic optimization

Abstract

Peer-to-peer (P2P) based content distribution systems have emerged as the main form for content distribution on the Internet, which can greatly reduce the distribution cost of content providers and improve the overall system scalability. However, the mismatch between the overlay and underlay networks causes large volume of redundant traffic, which intensifies the tension between P2P content providers and ISPs. Therefore, how to efficiently use network resources to reduce the traffic burden on the ISPs is crucial for the sustainable development of P2P systems. This paper surveys the state-of-art P2P traffic optimization technologies from three perspectives: P2P cache, locality-awareness and data scheduling. Technological details, comparison between these technologies and their applicabilities are presented, followed by a discussion of the issues that remain to be addressed and the direction of future content distribution research.

Location-aware and personalized collaborative filtering for web service recommendation

“…The Internet is composed of thousands of ASs that inter-connected with each other. Generally speaking, intra-AS traffic is much better than inter-AS traffic regarding transmission performance, such as response time [34]. Also, traffic between neighboring ASs is better than that between distant ASs.…”

Robustness analysis of location aware collaborative filtering for web service recommendation

“…They represented a user location as a triple (IP u, A SN u,C ountryID u), where IPu denotes IP address of the user hosts, A SN u denotes number of the Autonomous System (AS) that IP u belongs to, and C ountryID u denotes the ID of the country that IP u belongs to. Generally speaking, intra-AS traffic is much better than inter-AS traffic regarding transmission performance, such as response time (Zhang, 2012). Therefore, the Internet AS-level topology has been widely used to measure the distance between Internet users.…”

Information-centric networking with built-in network coding to achieve multisource transmission at network-layer

“…As a result, a 3 clean-slate architecture design paradigm has been suggested 4 to build the future Internet by the research community [1,2]. 5 In recent years, various research programs aimed at the However, in the original ICN proposal (referred to as ICN 40 in this paper), the consumer only uses the first returned con-41 tent, and any subsequent copies will be discarded when mul- 42 tiple data sources respond to the Interest.…”

“…In the paper, the term retransmit is used exclusively for end consumers re-expressing Interests; and another term retry is used when intermediate nodes explore alternative paths 4. Nonce is set to be a random value.…”
