TADKOM
TADKOM / TAktisk Digital KOMunikasjon (English: TADCOM / TActical Digital COMmunication) is an encrypted network used as a carrier for most of the communication for all four branches of the Norwegian military. Most nodes operate on a speed of 2mbit and above. TADKOM is also used to carry signals such as Link-11, Link-11B, Link-16 and Link-22(Future). The system use the X.25 X.25 is an ITU-T standard protocol suite for packet-switched data communication in wide area networks (WAN). It was originally defined by the International Telegraph and Telephone Consultative Committee (CCITT, now ITU-T) in a series of drafts a ... protocol to communicate between the nodes. TADKOM is classified for Nato Secret and National Secret without any additional encryption devices. Military radio systems {{radio-comm-stub ...

Norwegian Military
The Norwegian Armed Forces ( no, Forsvaret, , The Defence) is the military organization responsible for the defence of Norway. It consists of five branches, the Norwegian Army, the Royal Norwegian Navy, which includes the Coast Guard, the Royal Norwegian Air Force, the Home Guard, and Norwegian Cyber Defence Force as well as several joint departments. The military force in peace time is around 17 185 personnel including military and civilian staff, and around 70 000 in total with the current military personnel, conscripts and the Norwegian Home Guard in full mobilization. Among European NATO members, the military expenditure of US$7.2 billion is the highest per capita. History An organised military was first assembled in Norway in the 9th century and its early focus was naval warfare. The army was created in 1628 as part of Denmark–Norway, followed by two centuries of regular wars. A Norwegian military was established in 1814, but the military did not see combat until the Ge ...

Node (networking)
In telecommunications networks, a node (, ‘knot’) is either a redistribution point or a communication endpoint. The definition of a node depends on the network and protocol layer referred to. A physical network node is an electronic device that is attached to a network, and is capable of creating, receiving, or transmitting information over a communication channel. A passive distribution point such as a distribution frame or patch panel is consequently not a node. Computer networks In data communication, a physical network node may either be data communication equipment (DCE) such as a modem, hub, bridge or switch; or data terminal equipment (DTE) such as a digital telephone handset, a printer or a host computer. If the network in question is a local area network (LAN) or wide area network (WAN), every LAN or WAN node that participates on the data link layer must have a network address, typically one for each network interface controller it possesses. Examples a ...

Link-11
TADIL-A/Link 11 is a secure half-duplex tactical data link used by NATO to exchange digital data. It was originally developed by a joint committee including members from the Canadian Navy, US Navy and Royal Navy to pass accurate targeting information between ships. The final standard was signed in Ottawa in November 1957, where the British proposed the name "TIDE" for "Tactical International Data Exchange". It was later made part of the NATO STANAG standardization process. The system operates on two frequencies, one in the high frequency (HF) range for over-the-horizon (OTH) communications, and another in the ultra high frequency (UHF) range that uses much smaller antennas and is suitable for smaller ships but lacks the OTH performance. The system broadcasts packets of 30 bits length, with 6 bits of error correction and 24 bits of payload data. The payload is encrypted. Link 14 was adopted at the same time as a low-end counterpart to Link 11. Link 14 is essentially a digital t ...
