Definition: CYCLADES


A packet switched network developed by Louis Pouzin in France in the early 1970s. CYCLADES was the first communications network without central control. Each machine was responsible for sending and receiving data, and it greatly influenced the eventual design of the Internet protocol (TCP/IP). In 1981, CYCLADES was abandoned in favor of France's X.25-based Transpac network. See TCP/IP and X.25.
