“…Contrary to the original oracle, the use of pdistance interface by ISPs and P2P applications is very flexible due to simple and extensible of interface design. The Internet Engineering Task Force (IETF) is going to make a standardization called ALTO (application-layer traffic optimization) [12], [6] based on oracle-based system [5] and P4P [13].…”

Recently, peer-to-peer (P2P) traffic is increasing rapidly in volume day by day. One of the main causes is that most of P2P applications including file sharing and streaming applications often form overlay networks for exchanging data that are oblivious to the underlay network topology. As a result, they generate a large amount of inter-domain traffic causing higher cost for internet service providers (ISPs). This raises a problem of traffic localization.To optimize the cross-ISP/AS traffic, existing approaches focus on solving the problem on the application layer where each P2P application must be equipped with an additional protocol to obtain underlay network information from an "oracle" server or an additional locality-aware procedure to estimate location by itself. Therefore some modifications of application software are required for these approaches.In this paper, we propose a novel solution for addressing the problem, called PLS, forcing packet loss to each P2P packet based on geographical location of each destination at the network layer. Since PLS is implemented at a network router, no software modification is required. This proposal can be applied to all types of P2P applications in order to localize the traffic. The experiment in this study evaluated on popular P2P streaming applications show that our proposed method significantly improves the performance of traffic localization problem.

“…P2P clients can use this information for peer selection. The IETF has also recently formed the Application Layer Traffic Optimization (ALTO) working group that provides underlying network information to P2P clients with the help of ISPs or third parties [14]. Similarly, [15], [16] investigated node selection with the help of an ISP "oracle" according to ISP preferences.…”

Abstract-Underlay-unawareness in P2P systems can result in sub-optimal peer selection for overlay routing and hence poor performance. The majority of underlay aware proposals for peer selection focus on finding the shortest overlay routes by selecting the nearest peers according to proximity. However, in case of multiple and parallel downloads, if the underlay paths between a downloader and its selected nearest peers share a bottleneck, this can cause congestion, leading to performance deterioration instead of improvement. This effect was neglected in previous work because, in today's Internet, the bottleneck is usually not shared as it is the end user's access link. This is no longer the case in more modern scenarios, e.g. with FTTH or with upcoming innetwork caching techniques such as DECADE. We propose an improved peer selection approach for P2P applications called Fewest Common Hops (FCH) that ensures proximity based node selection having maximum path disjointness. It is a client based, infrastructure independent heuristic to optimize download time for multiple and parallel downloads in P2P content distribution applications. Simulations show that, even when FCH is implemented in the simplest possible fashion (using only traceroute), it can significantly decrease the download time.

“…The Working Group will consider the needs of BitTorrent, tracker-less P2P, and other applications, such as content delivery networks (CDN) and mirror selection. Recent developments in the IETF ALTO Working Group are summarized in [44]. Gurbani, Hilt et al also conduct a survey of research on the application-layer traffic optimization problem and the need for layer cooperation in [45], where the authors state that ALTO problem will be best achieved by enabling communications between the P2P application layer and the network layer.…”

The flourish of P2P systems draws a lot of attention of networking researchers. Some research efforts focus on P2P systems, trying to understand the mechanism of various implementations and the behavior pattern of P2P users, and then improve the systems' performance. Others look at the issue from the angle of ISPs, trying to help ISPs solve various issues brought by P2P applications. In this article, we conduct a review study on recent research efforts in these two areas. The first part of this article focuses on several key strategies that have significant influence on the performance of P2P systems. In the second part, we review some important techniques for ISPs to manage P2P traffic, i.e., blocking, caching and localization, and compare their advantages and disadvantages.
