Peer-to-Peer Technology
Description:
Since Napster appeared in 1999, various Peer-to-Peer (P2P) file sharing applications (e.g., WinMX, KaZaA, Gnutella, Freenet, winny) have jumped from shadow into the spotlight. Although Napster nor ICQ was the first P2P application, they were the first to use the standard of the internet as a backbone in their technology. The secret behind this P2P technology is that it enables electronical bi-directional communication. This is in contrast to client/server systems that require continuous polling of the client on the server, a technique with a very low efficiency, and forces centralization (and control) of knowledge. The number of software platforms that enable P2P communication is increasing heavily, and stimulates people to share information and digitalize our bi- or multi-directional communcation.
Enablers:
1. Software producers, consortiums (e.g. ISMIR), software free fighters.
2. User control (psychologic behavior of human beings)
3. Technological development
4. Development of internet infrastructure
5. Computer literacy
Inhibitors:
1. Intellectual rights, patents, or in general: knowledge protection (e.g. RIAA)
2. Regulations, restrictions, fear for instability or in general: control
Paradigms:
1. Free fighters, software companies and consortiums like
2. P2P file sharing applications will increase the usefulness of the internet to many potentials users that were not users before. By enabling bi- or multi-directional communication, and the ongoing globalization, they are motivated to make use of this new communication highway.
3. Technological development will give birth to more powerful and efficient new products and therefore will stimulate the distribution of powerful devicesfor low prices.
