The GIG Bandwidth Expansion program (GIG-BE) is a component of the overall GIG, that involves upgrading the capacity of the busiest equipment and transmission pathways composing the central portion of the GIG. 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. DOD is building a Global Information Grid (GIG) to provide a secure networking capability for managing information on demand for warfighters, policy makers, and support personnel. The GIG will provide a single network to enable sharing of information from sensors 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 future capabilities of the GIG. 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, and which use optical network technology. The Defense Information Systems Agency (DISA) is leading the Congressional Research Service + The Library of Congress 1 For more information about Network Centric Warfare, see CRS Report RS20557, Navy Network-Centric Warfare Concept: Key Programs and Issues for Congress.
