Global Information Grid (GIG) Bandwidth Expansion (GIG-BE)

The Global Information Grid (GIG) Bandwidth Expansion (GIG-BE) is key to realizing the Department's enterprise information environment. It is providing a worldwide, ground-based fiber-optic network that will expand Internet-Protocol (IP)-based connectivity and at the same time effectively and efficiently accommodate older, legacy command, control and communications (C3) systems. This enables an exponential leap in ground-based voice, video and data exchange capabilities for the Department of Defense and the Intelligence Community.

GIG-BE created a ubiquitous "bandwidth-available" environment to improve national security intelligence, surveillance and reconnaissance, and command and control information-sharing. To implement GIG-BE, DISA is aggressively enhanced the existing end-to-end information transport system, the Defense Information System Network (DISN), by significantly expanding bandwidth and physical diversity to selected locations worldwide. The program provides increased bandwidth and diverse physical access to approximately 100 critical sites in the continental United States (CONUS) and in the Pacific and European theaters. These locations are interconnected via an expanded GIG core. Specifically, GIG-BE connects key intelligence, command, and operational locations with high bandwidth capability over physically diverse routes, and the vast majority of these locations will be connected by a state-of-the-art optical mesh network design.

GIG-BE fully supports DoD's continuing investments in surveillance assets, reach-back, sensor-to-shooter integration, collaboration, and enterprise computing. Removing current bandwidth limitations provides the catalyst for self-synchronization, shared situational awareness, sustainability, and speed of command and action, allowing those closest to the reality of combat full access to a rich and enabling set of information assests.

In fiscal year 2002, DISA completed the required report to the Deputy Secretary of Defense, detailing validated requirements, technical design, analysis of alternatives, economic analysis, and implementation strategy for the GIG-BE. DISA also completed development of the GIG-BE Functional Requirements Specification, which will be used for acquisition of required transport media and equipment. DISA continues to work with DoD components to develop specific implementation details, including site surveys and operational responsibility assignments. In addition, DISA also workied with the intelligence community to identify opportunities for community asset-sharing in GIG-BE implementation, and DISA has participated in joint business case analyses to determine where partnership would result in efficiencies for both communities.

The GIG-BE reached Initial Operational Capability (IOC) at six sites on Sept. 30, 2004 at which time it wass scheduled to reach Final Operational Capability (FOC) at 92 sites by Sept. 30, 2005. Upon successful establishment of IOC, parallel implementation occur in CONUS and overseas.

DISA continues to plan for the transformation and optimization of DISN subsystems (voice, data, and video) via the GIG-BE, both in terms of physical topology and technology evolution, with the goal of providing multimedia service delivery (converged services) by the end of the decade.

In less than three years, the GIG-BE program moved from its original planning phase through its initial operational capability, and it reached full operational capability at the end of 2005. It represents a model for the close collaborative working relationships among all levels of Defense and Intelligence Community management that drive our corporate pursuit of network-centric operations. Under Defense Information Systems Agency (DISA) leadership, this program meets stringent COCOM, Service, Agency and national intelligence requirements, and it provides the ground-based foundation on which the Services and the Intelligence Community are basing complementary programs to deliver both superior combat effectiveness and effective and efficient peacetime operations in the future.

With an initial investment of $877 million, DISA delivered a secure and redundant, state-of-the-art, ground-based optical IP network to connect over eighty intelligence, command and control and operational locations throughout the continental U.S. and the Pacific, European and Southwest Asian theaters. By early 2005 twelve of these sites were fully implemented, and remaining installations were progressing on schedule.

As a global, high capacity, optical communications system, the GIG-BE program reduces bandwidth-constraints for data exchange and instead provides sufficiently increased bandwidth to support combat operations. Moreover, it provides physically diverse routing services for DoD and the Intelligence Community by expanding the Department's core telecommunications backbone. This greatly enhances the reliability and the survivability of the entire network.

Because the government now effectively owns the fiber and the optics of this network, it greatly facilitates the ability to upgrade its security and performance. Additionally, GIG-BE is critical to exploiting reach back capability, which will maximize continuing investments in critical airborne Intelligence, Surveillance and Reconnaissance and future combat support assets. With expanded bandwidth, the elimination of single points of failure and a high degree of network security and integrity, the GIG-BE program contributes significantly to meeting ground transport needs for voice, video and data.

The GIG-BE program is the first of its kind to bring high-speed, high assurance IP encryption (HAIPE) to DoD networks. The introduction of HAIPE devices, as a result of the National Security Agency?s anticipatory development, will greatly increase our ability to bring secure net-centric capabilities to Intelligence Community and DoD operations.

The GIG-BE program is delivering much needed capabilities to decision-makers and warfighters alike. It represents a clear and continuing commitment among Defense and Intelligence Community leaders to achieving net-centric capabilities, and it demonstrates an exceptional return on our investment in information superiority assets.
