Enabling Our Mission Partners

The DISN is the DOD consolidated worldwide enterprise-level telecommunications infrastructure that provides end-to-end information transfer network for supporting military operations. The enterprise-level networks are provided by DISA. For the most part, it is transparent to the joint force. The DISN facilitates the management of information resources, and is responsive to national security, as well as DOD needs. It provides Department of Defense Information Network (DODIN) services to DOD installations and deployed forces. Those services include voice, data, and video, as well as enterprise services such as directories and messaging. DOD policy mandates the use of the DISN for wide area and metropolitan networks.
