While existing research on peer-to-peer (P2P) file-sharing services has increased our understanding in many respects, it has not yet supplied a comprehensive theoretical framework that explains business failures of P2P file-sharing network service models. We develop such an analytical model and base it on seven specific market constraints – technical, economic, structural, legal, political, cog...

As the number of documents on the Web grows into the billions, the proportion of those documents available through indexing search engines shrinks.1,2 The amount of content available through the “hidden web” of searchable online databases might be 400 times larger.3 Application servers and network-enabled business systems have the potential to increase this content by many more orders of magnit...

In both academia and industry, peer-to-peer (P2P) applications have attracted great attentions. P2P applications such as Napster, Gnutella, FastTrack, BitTorrent, Skype and PPLive, have witnessed tremendous success among the end users. Unlike a client-server based system, peers bring with them serving capacity. Therefore, as the demand of a P2P system grows, the capacity of the network grows, t...

The peer-to-peer (P2P) paradigm for building distributed applications has recently gained renewed attention, partly due to the enormous success of systems like Napster and Gnutella. Subsequently, a multitude of projects focusing on anonymity, security, routing and reliability aspects of P2P have been initiated. A framework that supports the design, evaluation and implementation phases of P2P ap...

Many different service architectures, ranging from centralized client-server to fully distributed are available in today’s world for Content Distribution on the Internet. The IP Multicast seemed to be a wonderful technology with potential benefits for one-tomany or many-to-many content distribution applications. However, even after more than two decades of its invention, only very few commercia...

In recent years, various P2P network applications, Napster, Gnutella, WinMX, Winny and many others, have been developed. But it is difficult to find out suitable information resources and to guarantee practical response time by using distributed systems with simple search functions. Furthermore, most of applications are based on overlay networks with unstable network topology and query messages...

Although peer-to-peer networking applications continue to increase in popularity, there have been few measurement studies of their performance. We present the first study of the popularity of files stored and transferred among peers in Napster and Gnutella over month-long periods. Our analysis indicates that the popularity of files is skewed in all four cases and fits well to a log-quadratic di...

There are a variety of intermediate devices in the Internet today that require application intelligence for their operation. Datagrams pertaining to real-time streaming applications such as SIP and H.323 and peer-to-peer applications such as Napster and NetMeeting cannot be identified by merely examining packet headers. Middleboxes implementing Firewall and Network Address Translator services t...

Since the launch of Napster in June 1999, peer-to-peer (P2P) has become synonymous with file sharing applications that are the bane for the recording industry due to copyright infringements and revenue losses. P2P promised a revolution in business computing which has not arrived (DiSabatino 2000). Most P2P studies in the MIS area have focused on the file sharing P2P applications like Kaaza, etc...

We report results from a longitudinal analysis of the IP traffic workload seen at a single measurement site inside a major Internet traffic exchange point. Using data collected by the NLANR/MOAT Network Analysis Infrastructure (NAI) project [NAI] and analysis software from CAIDA’s CoralReef project [CoralReef], we present trends in application usage seen at the NASA Ames Internet Exchange over ...
