U.S. Air Forces Central Command Airman First Class Reginald Maffett, 455th Expeditionary Communications Squadron, network management technician.

A recent approach for the management of increasingly complex communications networks is software-defined networking (SDN) in which a programmable controller provides flow level routing instructions to the network forwarding elements. The controller provides switching functions through an open interface standard called OpenFlow.

Air Force scientists have developed a set of flow rules and network management tools for these OpenFlow networks. The system can identify adverse conditions on the SDN such as a failed link or a failed forwarding device. The controller can take further action such as load balancing or isolating the failed link or device. The system uses graph theory techniques and introduces the concept of phantom nodes to produce outputs that can be used by the controller to both proactively and reactively update flow rules.
