Avalanche is the name of a proposed peer-to-peer (P2P) network created by Pablo Rodriguez and Christos Gkantsidis at Microsoft, which claims to offer improved scalability and bandwidth efficiency compared to existing P2P systems. A peer-to-peer (or P2P) computer network is a network that relies on the computing power and bandwidth of the participants in the network rather than concentrating it in a relatively few servers. ... Microsoft Corporation, (NASDAQ: MSFT, HKSE: 4338) is a multinational computer technology corporation with global annual revenue of US$44. ... It has been suggested that this article or section be merged with Scale (computing). ...
The proposed system works in a similar way to BitTorrent, but aims to improve some of its shortfalls. Like BitTorrent, Avalanche splits the file to be distributed into small blocks. However, rather than peers simply transmitting the blocks, they transmit random linear combinations of the blocks along with the random coefficients of this linear combination - a technique known as 'network coding'. This technique removes the need for each peer to have complex knowledge of block distribution across the network (an aspect of BitTorrent-like protocols which the paper[1] claims does not scale very well). This article is about the protocol. ... In mathematics, linear combinations are a concept central to linear algebra and related fields of mathematics. ... Network coding is a field of information theory and coding theory and is a method of attaining maximum information flow in a network. ... For other senses of this word, see protocol. ...
Bram Cohen, the creator of BitTorrent, discussed the proposed Avalanche system in a post to his blog, which mentions some of its potential drawbacks.[2] He also mentions the Microsoft research paper's inaccuracies in the analysis of the BitTorrent protocol (some of the analysis in the paper being based on a version of the BitTorrent protocol which is several years out-of-date), as well as concerns about the proposed network coding being too resource-intensive to be practical. Bram Cohen (born 1975) is an American computer programmer, best known as the author of the peer-to-peer (P2P) protocol BitTorrent, as well as the first file sharing program to use the protocol. ...

In July 2007, Microsoft made the technology available as a public customer technology preview (CTP) of the resulting system, called Microsoft Secure Content Downloader (MSCD).
Businesses and peer communities, enabled and empowered by a partner state, will have to create a rich tapestry of immaterial value, and the thicker the surrounding immaterial value, the lighter our attachment to mere having will be.
Third, I create a definitional avalanche about knowledge as a noun, verb, form and content in etymology, psychology, epistemology & pedagogy, law and economics.
When I heard your presentation on P2P knowledge sharing, I realized that the SCR methodology is akin to P2P in that the successful rural person is passing his knowledge onto his poorer peers, often at no cost.
The reference implementation is written in Python and is released under the BitTorrent Open Source License (a modified version of the Jabber Open Source License), as of version 4.0.
Unfortunately the system adopted by KaZaA is considered by some to be flawed as it relies on the client accurately reporting their Participation Level and therefore it is easy to cheat with the many "unofficial" clients.
