“…Regarding the reduction of ISP costs, multiple solutions have been proposed. Examples include ISP peering , IP multicast, content distribution networks and P2P localisation [6], [13], [14]. Another technique that has received increased attention from the research community is traffic shaping, that relies on reducing peak traffic volumes.…”

There is growing evidence that mutually beneficial outcomes can be achieved when content distribution overlays and their underlying ISPs collaborate through open interfaces. However, most works in this area have focused on preference costs derived from symmetric network properties (e.g. RTT). The consideration of asymmetric preference costs is expected to benefit from the development of consolidated topology construction strategies that integrate the information provided by all participating ISPs and use it to produce an overlay topology with desirable global properties. In this paper we propose a generic model for the multi-domain consolidation of ISP preferences expressed as cost-annotated lists of groups of topology-equivalent peers. Using this model, we propose two consolidated topology construction strategies: Shared Cost, designed to provide a tradeoff for preference cost asymmetries, and Low Cost, designed to reduce the overall preference cost that the overlay imposes on all its underlying ISPs. We evaluate these two models through extensive simulations over a wide range of ISP and PID size distributions, and we show that preference consolidation can provide ISPs with outcomes more aligned with their preferences than those provided by nonconsolidated operation.

“…BitTorrent traffic is responsible for a large portion of the overall Internet traffic. Accordingly, a lot of attention has been devoted to optimizing BitTorrent clients, for example, to make them ISP friendly, via localizing data traffic [1]. However, these works have focused on traffic volume almost exclusively.…”

It is well-known that the BitTorrent file sharing protocol is responsible for a significant portion of the Internet traffic. A large amount of work has been devoted to reducing the footprint of the protocol in terms of the amount of traffic, however, its flow level footprint has not been studied in depth. We argue in this paper that the large amount of flows that a BitTorrent client maintains will not scale over a certain point. To solve this problem, we first examine the flow structure through realistic simulations. We find that only a few TCP connections are used frequently for data transfer, while most of the connections are used mostly for signaling. This makes it possible to separate the data and signaling paths. We propose that, as the signaling traffic provides little overhead, it should be transferred on a separate dedicated small degree overlay while the data traffic should utilize temporal TCP sockets active only during the data transfer. Through simulation we show that this separation has no significant effect on the performance of the BitTorrent protocol while we can drastically reduce the number of actual flows.

Modelling the Tradeoffs in Overlay-ISP Cooperation

The increasing demand for efficient content distribution using the Internet has fuelled the deployment of varied techniques such as peer-to-peer overlays, content distribution networks and distributed caching systems. These have had considerable impact on ISP infrastructure demand, motivating the development of protocols that enable mutually beneficial cooperative outcomes.In this paper we propose a parameterised cooperation utility that can be used to study the tradeoff between the benefit that an overlay obtains from the ISPs that carry its traffic and the costs that it imposes on them. With this utility, we find a closed-form expression for the optimal resource allocation given a particular cooperation tradeoff, subject to both minimal benefit and maximal cost constraints. Since the model is implementation-independent and has very modest computational demands, it is ideal for large scale simulation. We explore the properties of the proposed model through simulation in both a simple illustrative scenario and a more complete one based on network datasets. The results obtained from the model are shown to be consistent with those of measurement-based studies of overlay-ISP collaboration.
