Even though recent research has identified many different uses for peer-to-peer (P2P) architectures, file sharing remains the dominant (by far) P2P application on the Internet. Despite various legal problems, the number of users participating in these file-sharing systems, and number of files transferred, continues to grow at a remarkable pace. Filesharing applications are thus becoming an incr...

Electronic commerce technology is more and more present and people are getting connected together. Companies and users want to automate their task and discover new business opportunities. Many standards and initiatives have been already proposed. Most of them focus on business-tobusiness protocol definition. Rosettanet, cxml, xcbl and bizTalk are only a few examples. Users and companies then ha...

Since the appearance of Napster in early 1999, peer-to-peer (P2P) networks have experienced tremendous growth. The P2P architectures can be categorized into two main classes: unstructured and structured P2P overlays. Unstructured overlays do not impose a rigid relation between the overlay topology and the indices/resources placement, as flooding or random walks are used to locate resources [3]....

Emerging 3D printing technologies bring with it the potential to transform everyday consumers into manufacturers of every product imaginable. However, this impending wave of newfound technological capability is bound to crash against our present conventional system of laws and regulations. In this paper, the strengths and weaknesses of our current intellectual property framework are examined, a...

Sep Kamvar’s monograph presents work from his 2004 thesis on how numerical algorithms are a critical component in search systems. Kamvar focuses on the new information networks arising in the late 1990s and early 2000s. When originally published, these results were groundbreaking and resulted in an NSF press release and even a Slashdot listing. 2 The book is divided into two parts, one for each...

Peer-To-Peer(P2P) networks are becoming ubiquitious.There are different kinds of P2P architectures and each of the architecture has its own merit and demerits. Peers interact and make decisions based on the local information. This local decisions have impact on the global behavior of the network. As a part of this project, first we model the dynamics involved in the network construction phase a...

The phenomenal growth of information technology, and of the Internet in particular, is profoundly altering the way we view and interact with each other. The new technologies have already produced sweeping changes in many aspects of our daily lives and show no sign of slowing down. What appear at first sight to be relatively unimportant technical or legal problems often end up raising serious et...

W eb portals and ISPs such as AOL, Microsoft Network, and Yahoo have grown more than tenfold in the past five years. Despite their scale, growth rates, and rapid evolution of content and features, these sites and other “giant-scale” services like instant messaging and Napster must be always available. Many other major Web sites such as eBay, CNN, and Wal-Mart, have similar availability requirem...

I INTRODUCTION The recent emergence of novel network applications such as Gnutella, Freenet, and Napster has reincarnated the familiar peer-to-peer (P2P) architecture model of the original Internet in new and innovative ways in an effort to facilitate worldwide sharing of information [1]. As a result, there is an ever-increasing need for distributed protocols that would allow peer-to-peer appli...
