Pure Peer-to-Peer (P2P) System

A Pure Peer-to-Peer (P2P) System is a Peer-to-Peer System that without a central server.

• Example(s):
  • Gnutella,
  • …
• Counter-Example(s):
  • Hybrid P2P System,
  • Centralized Client-Server System.

  • QUOTE: The Peer-to-Peer architecture is split into pure and hybrid architectures. The pure architecture works without a central server(...)

    In this architecture each peer is an equal participant. There is no peer with special or administrative roles. According to the definition, no central server is needed to control and coordinate the connections between the peers, see Figure 2. Therefore nodes have to self-organize themselves, based on whatever local information is available and interacting with locally reachable nodes (neighbors). Normally the data within such systems is distributed across multiple peers. Today pure Peer-to-Peer architecture does mostly exist in the area of file sharing (e.g. Gnutella).
