Defense unveils latest enterprise road map

Defense CIO John Stenbit has signed off on a new version of the Global Information Grid.

The Defense Department released Version 2.0 of its enterprise architecture. It incorporates what DOD has learned during its military operations in Afghanistan and Iraq, said John Osterholz, director of architecture and interoperability in the CIO office. It is Osterholz's job to develop the enterprise architecture.

GIG is a network of networks that will securely connect everything from sensors and satellites. DOD issued the first version of the GIG architecture in 2001.

DOD expects to complete all of the GIG layers, including communications and applications, late in this decade. Tightly integrated IP communications will be a key component, Osterholz said.

'All DOD IT and national security systems acquisitions' must comply with the GIG architecture, he said.

This includes the Army's Future Combat Systems, the Navy's ForceNet, DOD's Transformational Communications System and the department's Business Enterprise Architecture.

'The GIG architecture contains an operational view, which describes what is different about network-centric operations; a systems view, which integrates major systems end to end; and a technical view, which contains the largely commercial set of standards needed for procurement of net-centric capabilities,' Osterholz said.
