=== Catenet ===
Catenet, a short-form of ''(con)catenating networks,'' is obsolete terminolgy for a system of [[packet-switched]] communication networks interconnected via [[Gateway (telecommunications)|gateways]].<ref name="ien48" />

The term was coined by [[Louis Pouzin]], who designed the [[CYCLADES]] network, in an October 1973 note circulated to the [[International Network Working Group]],<ref>{{Cite journal |last1=Russell |first1=Andrew L. |last2=Schafer |first2=Valérie |date=2014 |title=In the Shadow of ARPANET and Internet: Louis Pouzin and the Cyclades Network in the 1970s |url=https://www.jstor.org/stable/24468474 |journal=Technology and Culture |volume=55 |issue=4 |pages=893–894 |issn=0040-165X |jstor=24468474}}</ref><ref name=":02">{{Cite journal |last=McKenzie |first=Alexander |date=2011 |title=INWG and the Conception of the Internet: An Eyewitness Account |journal=IEEE Annals of the History of Computing |volume=33 |issue=1 |pages=66–71 |doi=10.1109/MAHC.2011.9 |issn=1934-1547 |s2cid=206443072}}</ref> which was published in a 1974 paper "''A Proposal for Interconnecting Packet Switching Networks"''.<ref>''A Proposal for Interconnecting Packet Switching Networks'', L.

Catenet was the concept of linking these networks into a ''network of networks'' with specifications for compatibility of addressing and routing. The term was used in technical writing in the late 1970s and early 1980s,<ref>{{Cite web |title=catenet - Google Search |url=https://www.google.com/search?udm=36&q=catenet&safe=active&ssui=on |access-date=2025-04-28 |website=www.google.com}}</ref> including in [[Request for Comments|RFCs]] and [[Internet Experiment Note|IENs]].<ref>{{Cite web |title=Google Search |url=https://www.google.com/search?q=catenet+site:https://www.rfc-editor.org/&safe=active&ssui=on |access-date=2025-04-28 |website=www.google.com}}</ref> Catenet was gradually displaced by the short-form of the term internetwork, ''internet'' (lower-case ''i''), when the [[Internet Protocol]] spread more widely from the mid 1980s and the use of the term internet took on a broader sense and became well known in the 1990s.<ref>{{Cite web |title=Google Books Ngram Viewer |url=https://books.google.com/ngrams/graph?content=catenet,internet&year_start=1970&year_end=1995&corpus=en&smoothing=3&case_insensitive=false |access-date=2025-04-28 |website=books.google.com |language=en}}</ref><ref>{{Cite IETF |RFC=1011}}</ref><ref>{{Cite IETF |RFC=1087}}</ref><ref>{{Cite IETF |RFC=1392}}</ref><ref>{{Cite IETF |RFC=1462}}</ref><ref>{{Cite IETF |RFC=1935}}</ref><ref>{{Cite IETF |RFC=1958}}</ref><ref>{{Cite IETF |RFC=2002}}</ref>
