Peer-to-peer is emerging as a potentially disruptive technology for content distribution in the mobile Internet. In addition to the already well-known peer-to-peer file sharing, real-time peer-to-peer streaming is gaining popularity. This paper presents an effective real-time peer-to-peer streaming system for the mobile environment. The basis for the system is a scalable overlay network which groups peer into clusters according to their proximity using RTT values between peers as a criteria for the cluster selection. The actual media delivery in the system is implemented using the partial RTP stream concept: the original RTP sessions related to a media delivery are split into a number of so-called partial streams according to a predefined set of parameters in such a way that it allows low-complexity reassembly of the original media session in real-time at the receiving end. Partial streams also help in utilizing the upload capacity with finer granularity than just per one original stream. This is beneficial in mobile environments where bandwidth can be scarce.

Network coding is a data transmission technique which allows intermediate nodes in a network to re-code data in transit. In contrast to traditional network communication where a node repeats incoming data to its outgoing channel without modifying the payload, a node implementing network coding not only repeats but also alters data. Network coding has been demonstrated to increase network throughput compared to the traditional forwarding transmission. It has potentially broad applications in many areas, including traditional computer networks, wireless ad-hoc networks, and peer to peer systems. This paper process a new technique for file sharing in P2P.

The general public is used to thinking of copyright (if it thinks of it at all) as marginal and arcane. But copyright is central to our society’s information policy and affects what we can read, view, hear, use, or learn. In 1998 Congress enacted new laws greatly expanding copy owners’ control over individuals’ private uses of their works. The efforts to enforce these new rights laws have resulted in highly publicized legal battles between established media, including major record labels and motion picture studios, and upstart internet companies such as MP3.com and Napster.In this book, I question whether copyright laws crafted by lawyers and their lobbyists really make sense for the vast majority of us. Should every interaction between ordinary consumers and copyright-protected works be restricted by law? Is it practical to enforce such laws, or expect consumers to obey them? What are the effects of such laws on the exchange of information in a free society? My critique exposes the 1998 copyright law as an incoherent patchwork. I argues for reforms that reflect the way people actually behave in their daily digital interactions.The Maize Books edition includes both an afterword written in 2006 exploring the rise of peer-to-peer file sharing and a new Postscript reflecting on the consequences of the Digital Millennium Copyright Act as it nears its twentieth birthday.
