The IT world according to DOD

C2 Constellation: Air Force's planned peer-to-peer network meshing command, control, communications, computers, surveillance, intelligence and reconnaissance systems with airborne and space-based sensors.

DRSN: Defense Red Switched Network, a voice network for Secure Telephone Units, tactical phones and satellite terminals.

DSN: Defense Switched Network, a voice, video and data network with dial-up access to NIPRnet and SIPRnet as well as the Government Emergency Telephone System.

DISN: Defense Information System Network, the backbone WAN incorporating Defense Red Switched Network (secure voice), Defense Switched Network (voice), DISN Video Services, Joint Worldwide Intelligence Communications System, Non-Classified IP Router Network (NIPRnet) and Secret IP Router Network (SIPRnet).

DREN: Defense Research and Engineering Network, hosted by MCI and facing transition from IP Version 4 to IP Version 6.

Echelon: Global telecommunications surveillance network.

ForceNet: Navy's plan by 2010 to integrate IP network grids for command, control, communications and computers; sensors; and weapons. Combines IT-21 sea warfare and Navy-Marine Corps Intranet systems.

Future Combat Systems: The Army's plan to network 16 manned and unmanned ground and aerial vehicles with sensors that feed soldiers up-to-date situational information.

GIG: Global Information Grid, a worldwide mesh to supply information on demand to warfighters, policy makers and support personnel. It will encompass all Defense-owned and -leased communications and computing systems, software, data and security services.

GIG-BE: 10-year, $1 billion Global Information Grid Bandwidth Expansion project to build a 10-Gbps switched optical network worldwide.

Intelink: Classified intranet for intelligence users.

IT-21: The Navy's tactical radio and satellite links to Navy ships at sea for command, control, communications, computers, intelligence, surveillance and reconnaissance.

Joint Tactical Radio System: Program to develop and deploy a Defense-wide digital radio system.

Navy-Marine Corps Intranet: Seat-management contract for voice, video and data connectivity on land and sea.

Net-Centric Enterprise Services: Created by the Defense Information Systems Agency, NCES provides enterprise services in support of the GIG.

NIPRnet: Non-Classified IP Router Network for unclassified but sensitive communications.

Single Integrated Space Picture: Air Force initiative to consolidate systems into a single source of space information.

SIPRnet: Secret IP Router Network, supporting the Defense Message (e-mail) and Global Command and Control systems.

TCA: Transformational Communications Architecture, an end-to-end architecture across DOD, intelligence agencies and NASA. The terminal segment would consist of end users, ground stations, and space and airborne terminals. The space segment would have two interoperable satellite constellation rings. The terrestrial segment would interface with other DOD networks, teleports, NASA, and selected ground systems for uplink and downlink.

WIN-T: Warfighter Information Network-Tactical, the Army's high-speed, high-capacity network for wired and wireless voice, data, video and imagery for the battlefield.
