CYCLADES was one of the first packet switching computer networks. CYCLADES was developed in France, and it's development was influenced by earlier packet switching networks, such as: ARPANET and Mark I. Some of the chief designers of CYCLADES are listed below:

  1. Hubert Zimmermann
  2. Louis Pouzin

CYCLADES is named after the Greek island group in the Aegean Sea. The Cyclades islands form a archipelago: a group of islands that are typically governed by a standard set of laws. Likewise, the architecture of the CYCLADES computer network was built upon a similar idea: a group of computer networks, who communicated using a standard protocol suite.

CYCLADES was an influential computer network: as it built and improved upon the network architecture of ARPANET. CYCLADES pioneered the development of end-to-end protocols: where hosts, instead of the network, was responsible for the delivery of data. This was a revolutionarily idea: as previously networks, like ARPANET, relied on the network to deliver data.

Designing CYCLADES began in 1972, and a working example of the network was displayed in 1973. The network was fully deployed between 1974-1976, and included nodes across the European continent. CYCLADES was designed with a protocol suite that featured layers, and the packet structure/function was named CIGALE. CYCLADES pioneered and coined the term: datagram.

CYCLADES spearheaded the development of packet switching networks that featured a simple and basic central data transport protocol. The intelligent functions of the network were handled by the hosts: which made it far simpler, than previously, to interconnect new nodes and networks together.

CYCLADES was influential in the development of TCP/IP and the OSI network model. Both of these protocol suites would copy CYCLADES layered model and end-to-end protocol structure, where hosts were responsible for the delivery of data.
