Modern expeditionary military missions generate and exchange massive amounts of data that are used to produce situational awareness and guide decision-making. Much of the data must travel long distances along backbone communications networks composed of high-capacity links that interconnect command centers.
The continued growth in unmanned, sensor, and networked devices is expected to drive the need for larger, more capable and more diverse communications systems. Among other enhancements, these systems must improve jam-resistance and low probability of detection to keep pace with adversaries’ growing electronic sophistication and must adapt to fast-changing operational environments. By contrast, today’s military communications architectures are static and inflexible.
Information, or ‘content’, on the World Wide Web is replicated and distributed across the world to ensure high availability to the end-user. User expectations for rapid access to content have led to the creation of content distribution systems that enhance the user experience. Consequently, users may quickly access content used for everyday living, from restaurant menus and maps, to local and world news.
In the current art, users with significant computing requirements have typically depended on access to large, highly shared data centers to which they backhaul their data (e.g., images, video, or network log files) for processing. However, in many operational scenarios, the cost and latency of this backhaul can be problematic, especially when network throughput is severely limited or when the user application requires a near real-time response. In such cases, users’ ability to leverage computing power that is available “locally” (in the sense of latency, available throughput, or similar measures that are relevant to the user or mission) could substantially improve application performance while reducing mission risk.
The Dynamic Network Adaptation for Mission Optimization (DyNAMO) program is developing and testing technologies that enable adaptive, mission-responsive networking among diverse platforms in contested environments.
