Summary
The Global Information Grid (GIG) is the enabling infrastructure for Network
Centric Warfare (NCW), a concept that relies on communications technology to link
together U.S. military personnel, ground vehicles, aircraft, and naval vessels through
integrated wide and local area networks to provide improved battle space awareness for
joint military forces.1 The GIG Bandwidth Expansion program (GIG-BE) is a
component of the overall GIG which upgrades the transmission pathways composing the
central portion of the GIG. The GIG-BE program achieved full operational capability
as of December 20, 2005, however, some question whether the GIG-BE design will
support military requirements for transmitting the expected future high volume of
encrypted network traffic. Also, because each service is developing a separate network
architecture that will tie into the GIG, some observers question whether these
differences will limit interoperability of the overall GIG, and thus reduce its usefulness
to warfighters. This report will be updated as events warrant.
Background
Global Information Grid. The DOD Global Information Grid (GIG) provides a
secure networking capability for managing information on demand for warfighters, policy
makers, and support personnel. The GIG is a single network that enables communications
and sharing of sensor information among personnel at multiple levels of security in all
services, in the intelligence community, and with U.S. coalition partners. The
functionality of many sophisticated weapons systems may be critically dependent on the
capabilities and reliability of the GIG.
Status of the GIG-Bandwidth Expansion Program (GIG-BE). The GIG
network design includes linkages through radio, satellite, and land lines. The GIG-BE
program enhances the high-speed land lines which form a central core of the GIG by using
optical network technology.
