This document discusses peer-to-peer (P2P) networks and centralized client-server (C/S) networks. It provides statistics on internet traffic by application type, showing P2P applications like BitTorrent account for the majority of traffic. The document also examines features of P2P networks like file sharing, distributed data storage, and compares them to C/S architectures. It proposes a new P2P network that would provide centralized control over applications like BitTorrent along with security features and user databases.
