Defense Information Systems Network - DISN End-to-End Infrastructure Responsibilities

DISN End-to-End Infrastructure Responsibilities

The DISN end-to-end infrastructure is composed of three major segments:

• The sustaining base (I.e. base, post, camp, or station, and Service enterprise networks). The Command, Control, Communications, Computers and Intelligence (C4I) infrastructure will interface with the long-haul network to support the deployed warfighter. The sustaining base segment is primarily the responsibility of the individual Services.

• The long-haul transport infrastructure, which includes the communication systems and services between the fixed environments and the deployed Joint Task Force (JTF) and/or Coalition Task Force (CTF) warfighter. The long-haul telecommunications infrastructure segment is primarily the responsibility of DISA.

• The deployed warfighter, mobile users, and associated Combatant Commander telecommunications infrastructures supporting the Joint Task Force (JTF) and/or Coalition Task Force (CTF). The deployed warfighter and associated Combatant Commander telecommunications infrastructure is primarily the responsibility of the individual Services.
