متن کاملPeer-to-Peer Systems
Peer-to-peer technologies (or P2P for short) have broken through in recent years as an attractive alternative to the traditional client-server-based architectures and systems. A lot of the attention paid to peer-to-peer systems has been caused by the widespread use of P2P file sharing networks, where (often illegal) media content is being distributed. Recently deployed peer-to-peer systems howe...
متن کاملPeer-to-Peer Systems
This paper provides a brief introduction to peer-to-peer (P2P) systems. Basic definitions and characteristics of P2P systems are described in Section 1. A comparison of a two related paradigms: P2P and Grid computing is also given. Section 2 classifies P2P substrates into two categories: structured and unstructured. Description of each category along with some examples is provided. A wide range...
