To increase combat effectiveness by networking the warfighter and to easily modify and expand its existing network architecture, the United States Navy requires shipboard computer systems that are network-centric and service-based and that support open architectures. However, they are limited by the radio frequency bandwidth that is available for shipboard communications. As a result, some network applications must take priority over others. The current Navy prioritization scheme was not designed with the needs of the warfighter as the primary focus nor does it allow for dynamically changing priorities based on changing threats. A prioritization scheme is proposed that optimizes network performance based on warfighter needs. The scheme is developed using the Capabilities-Based Competency Assessment process introduced by Suttie Potter 2008 applied to an air detect-to-engage scenario for a carrier strike group underway. A comparison is made between the proposed prioritization scheme and traditional Navy schemes using simulation. Results show our prioritization scheme consistently reduced latency and increased throughput for mission relevant applications. These improvements translate directly to more relevant information getting to decision-makers sooner, which leads to information superiority, ultimately enhancing warfighting capability.
