“…Both Susitaival et al [20] and Wong et al [22] relate the busy period of the M/G/∞ queue to content availability in BitTorrent. Menasche et al [12] model the availability of chunks in a swarm using a set of M/G/∞ queues in tandem, under assumptions similar to those of coupon collector systems.…”

“…Menasche et al [12] model the availability of chunks in a swarm using a set of M/G/∞ queues in tandem, under assumptions similar to those of coupon collector systems. Our model differs from [20,22,12] in two ways as it 1) quantifies content availability while accounting for publisher dynamics, and 2) quantifies the impact of bundling on availability and download time.…”

“…A user seeking one episode of a TV show may decide to fetch the entire season for possible future viewing. A publisher might recommend a movie as part of a bundle to a user who may preview it and choose to pay for it after all [16,22]. Even a small fraction of users opting to download more content than they strictly sought can significantly improve availability.…”

BitTorrent, the immensely popular file swarming system, suffers a fundamental problem: content unavailability. Although swarming scales well to tolerate flash crowds for popular content, it is less useful for unpopular content as peers arriving after the initial rush find the content unavailable.Our primary contribution is a model to quantify content availability in swarming systems. We use the model to analyze the availability and the performance implications of bundling, a strategy commonly adopted by many BitTorrent publishers today. We find that even a limited amount of bundling exponentially reduces content unavailability. Surprisingly, for swarms with highly unavailable publishers, the availability gain of bundling can result in a net improvement in download time, i.e., peers obtain more content in less time. We empirically confirm the model's conclusions through experiments on PlanetLab using the mainline BitTorrent client.

Internet growth has allowed unprecedented widespread access to cultural creation including music and lms, to knowledge, and to a wide range of consumer information. At the same time, it has become a huge source of business opportunities. Along with great bene ts that this access to the Internet provides, the open and free access to the Internet has encountered large opposition based on political, economical and ethical reasons. An ongoing battle over the control on Internet access has been escalating on all these fronts. In this paper we describe rst some of the ideological roots of free access to the Internet along with its main opponents. We then focus on the problem of Internet piracy and analyze the e ciency of e orts to reduce the availability of copyrighted creations that are available for non-authorized free download.

Recent publications have reached conicting conclusions on wheather allowing users to have unlimitted free access for downloading music and lms is benetial or not for the content provider industrty. Not only do models dier in their conclusions, but there has also not been an agreement on the validity of data on the impact of free access to music and lms using P2P on the prots of CPIs and on the demand for CDs and DVDs. We provide in this paper a model that allows to study this question using elementary mathematical tools. In particular, it includes the eect of sampling on the the willingness to buy. Preliminary numerical experiments show that benets are maximized by avoiding any control measures against unauthorized sampling over P2P networks.
