Enabling Peer Cooperation in Private Local Area Networks using BitTorrent

Abstract

The number of computers and high-speed networks connected to the Internet in large-scale organizations has grown in the last two decades. As a consequence, a large number of software applications must be installed and the quantity of data neededfor their operation is considerable. This has a high price for IT departments: distribute this content efficiently. We claim that content distribution using P2Pfile sharing systems can be used to accomplish this; we propose a solution that works even in environments that use NAT and utilizes WAN links efficiently.

BiT-SiEm: A packet-level simulation and emulation platform for BitTorrent

“…These abstractions make our platform useful not only for our simulator, but also for other uses such as creation of application-level protocols. That is, use BiT-SiEm not only in academic and scientific research scenarios, but also in industry for software development and testing (Aguilar et al, 2007). Also, this platform can be used for stress and load testing of concurrent applications by putting heavy loads on the tested parts.…”

“…For starters, typical systems tend to suffer as the number of hosts increases, which degrades quality of service (QoS) and in some cases generate denial of service (DoS). In client/server schemes providing some level of scalability implies high costs in terms of infrastructure, management and maintenance (Aguilar, Ege, Makki, & Bustos, 2007). Also, fault tolerance in these scenarios is not easy to implement since servers become a single point of failure, and consequently, costs to have replicated services are higher as the number of hosts increases.…”

Characterisation, design and simulation of an efficient peer-to-peer content distribution system for enterprise networks

“…BitTorrent [23,27] is a P2P system used for content distribution; in this approach the source file is broken, sent to different hosts, then the destination has to recover it from the different sources. BitTorrent distinguishes two types of peers: seeds and downloaders.…”

“…Estudos atuais (IPOQUE, 2009SANDVINE, 2011) BitTorrent em outras áreas além daquela para qual foi desenvolvido, como, por exemplo, streaming de vídeos (BAKKER et al, 2010;PARVEZ et al, 2012;SHAH;PARIS, 2007), distribuição de arquivos em redes locais (AGUILAR et al, 2007;THOMPSON;BROOKS;GREER, 2008) e distribuição de dados em redes veiculares sem fio (SHRESTHA et al, 2008).…”
