P2P: New technology SET promises quicker Downloads

SET was developed by David G. Andersen, a computer scientist and Michael Kaminsky (Intel Research Pittsburgh). SET stands for “Similarity Enhanced transfer”.

The principle: So far a download can only take place in P2P network, if an identical and complete file is present. SET is to make the download possible if a similar file is present, by identifying parts of the files, those is identical with parts of the file the user needs.

The two researchers are sure that by using SET the number of potential download sources rises enormously and again there is an increase in download speeds. As to how much the download speed rises, depends on the size and the popularity of the desired file. It should be possible to increase speeds from between five per cent right up to five times faster.

A peer-to-peer (or P2P) computer network relies primarily on the computing power and bandwidth of the participants in the network rather than concentrating it in a relatively low number of servers. P2P networks are typically used for connecting nodes via largely ad hoc connections. Such networks are useful for many purposes. Sharing content files (see file sharing) containing audio, video, data or anything in digital format is very common, and realtime data, such as telephony traffic, is also passed using P2P technology.A pure peer-to-peer network does not have the notion of clients or servers, but only equal peer nodes that simultaneously function as both "clients" and "servers" to the other nodes on the network. This model of network arrangement differs from the client-server model where communication is usually to and from a central server. A typical example for a non peer-to-peer file transfer is an FTP server where the client and server programs are quite distinct, and the clients initiate the download.
