Network Technology

I2O explores game-changing technologies in the fields of information science and software to anticipate and create rapid shifts in the complex national security landscape. Conflict can occur in traditional domains such as land, sea, air, and space, and in emerging domains such as cyber and other types of irregular warfare. I2O’s research portfolio is focused on anticipating new modes of warfare in these emerging areas and developing the concepts and tools necessary to provide decisive advantage for the U.S. and its allies.

Modern society depends on information and information depends on information systems. Timely, insightful, reliable, and relevant information drives success. This is not lost on military leaders who well appreciate the critical importance of information for national security. As Sir Francis Bacon wrote in 1597, “Knowledge is power.”

ARPA research played a central role in launching the “information revolution,” including developing or furthering much of the conceptual basis for ARPANET, a pioneering network for sharing digital resources among geographically separated computers. Its initial demonstration in 1969 led to the Internet, whose world-changing consequences unfold on a daily basis today. A seminal step in this sequence took place in 1968 when ARPA contracted BBN Technologies to build the first routers, which one year later enabled ARPANET to become operational.

As part of the then three-year-old Quantum Information Science and Technology (QuIST) program, DARPA-funded researchers established the first so-called quantum key distribution network, which is a data encryption framework for protecting a fiber-optic loop that connects facilities at Harvard University, Boston University, and the office of BBN Technologies in Cambridge, Mass.

The Department of Defense (DoD) maintains one of the largest computer networks in the world. The network follows DoD personnel across the globe collecting, transferring and processing information in forms as diverse as data warehouses, in-the-field mobile devices and mission computers on board F-18’s. This network is also constantly changing in size and shape as new missions are undertaken and new technology is deployed. In military terms, that means the cyber terrain of the DoD network is constantly shifting.
