Mission-Centric Content Sharing Across Heterogeneous Networks

New airborne communication technologies solve pressing capability requirements but often at the cost of cross-platform compatibility. We present an architecture and prototype constructed under the DARPA DyNAMO program specifically designed to address information flow across different underlying tactical data links by managing the dissemination of mission-critical information across an overlay network optimized for this purpose. Our architecture has two parts, an Information Gateway providing a content-based publish-subscribe service to applications, and a Network Optimizer providing path management and service quality control. We have implemented DyNAMO within an EMANE real-time emulation environment, and evaluated it over multi-data link networks. The results show that DyNAMO optimizes the available capacity across heterogeneous networks, targets and shapes information to work within the network resources, and maximizes information sharing.
