peertopeerteknikker

Peertopeerteknikker, often shortened to P2P-teknikker, refers to a class of distributed system architectures and communication protocols where individual nodes, or "peers," directly interact with each other without relying on a central server. This decentralized approach allows peers to share resources, such as files, processing power, or bandwidth, directly with other peers.

The fundamental principle behind P2P-teknikker is the elimination of a single point of failure and a potential bottleneck. Instead of clients requesting information from a central server, peers connect and exchange data amongst themselves. This can lead to increased scalability, as the system's capacity grows with the number of participating peers.

There are various categories of P2P-teknikker. Some systems utilize a centralized index or tracker to help peers discover each other, though the actual data transfer remains peer-to-peer. Other systems employ fully decentralized discovery mechanisms, such as distributed hash tables (DHTs), to locate resources and peers without any central coordination. File sharing applications, such as BitTorrent, are a well-known example of P2P-teknikker in action, enabling users to download and upload files simultaneously from and to multiple other users. Beyond file sharing, P2P-teknikker are also applied in areas like video streaming, online gaming, and distributed computing.
