Major programs within DISA

Defense Research Engineering Network. DREN is a 10-year, $450 million contract with WorldCom Inc. to build a high-speed research network for 6,000 scientists and researchers. The network will bring long-haul telecommunications to Defense Department laboratories, test centers, universities and industrial sites. Networking services for DREN are currently provided by a virtual WAN built on a public communications network supplied by AT&T.

Global Command and Control System. This framework combines more than 40 command and control systems into a single, integrated view of the battlefield for U.S. and allied forces. GCCS is fielded at more than 600 sites worldwide on DOD's classified intranet. It is made up of database servers, applications servers and clients.

Defense Message System. This system lets users sign messages with digital signatures and can trace each step a message takes from sender to receiver. DMS will replace AUTODIN, the 50-year-old bulk messaging system through which users ship electronic memos via military message centers. AUTODIN operates at a much slower speed than DMS and can only support text messages.
