The National Research and Academic Network of Greece the period 1984 -1995, also known as Ariadne, Ariadne network, Ariadne-t, initiated in 1984 as Programme Ariadne by Nicolas Malagardis under the Ministry of Research and Technology, in line with R&D policy of the EU Commission and became founding member of COSINE and RARE, with contributions to its technical reports. In 1987 the first full packet switching node in Greece connected to the French X.25 node in Paris at 9.6K bps via a local HELPAK line from OTE in Athens and a . was published in 1988. In 1988, the General Secretariat of Research and Technology assigned a new management for Programme Ariadne to be Prof. Costantine Halatsis, director at the "Demokritos". All facilities were relocated to the campus of Demokritos, at Agia Paraskevi, Attica from downtown Athens. As a RARE member Ariadne participated to the joining with RIPE with CERN via Olympus satellite and an SRI International report requested a contributing . In 1992 Ariadne supported by Brian Carpenter established a 9.6kbit/s direct link to CERN that later became part of EBONE, a network map shows the status of the network in 1993. During 1992-1994 the EU's DGXIII VALUE II project - v.5805 "Open Systems Interconnection national nodes and Administrators" assigned to the of the nationalresearch center "Demokritos" was implemented that devised a mixed technology plan that resulted in large scale development of internet connectivity to universities, government, and SMEs. The project registered in DNS as "EPMHS dot GR", the pattern "MHS" signifying the main application being messaging and gateways based on that required both technologies OSI and IP. Ariadne became almost self-financed by more than 80 partner contributions and the Ariadne dial-up Internet Service. In 1994, the general secretariat for research and technology assigned a new manager and support organization to Prof. V.Maglaris of National Technical University. The network operations center was relocated to the NationalTechnical University campus, a new satellite 256 kbit/s uplink to Delivery of Advanced Network Technology to Europe, as well as a new network nameGRNET and plan was created using the resources and people of Ariadne. Migration of sites to the newly designed network took 2–3 years to complete. Notable sites such as the Parliament of Greece, the National Observatory, the Atomic Energy Authority continued for several years their connection to Ariadne. In 1995 "Demokritos", National Technical University and the Greek Telecom OTE jointly established a new company OTENET as the nationwide ISP using the experience of Ariadne. IN 1997–1998 Ariadne participated in projects such as national network inter-connection experiments and ' based on ATM and Eutelsat. In 2002, the computer center of "Demokritos" created post-humously a for Ariadne using some original graphic designs. In 2014 "Demokritos" transferred its shares of DANTE to the newly formed Terena Association, as the legal entity representing Greece in DANTE as shown in the . Currently, Ariadne, as shown in the RIPE whois , is the campus network of "Demokritos", the main Data-Center, a LIR for collaborating organizations based at the of the Institute of Informatics and Telecommunications, it is a major GRNET site, hosting its metropolitan area network and Hellasgrid nodes.
