Abstract: Systems, methods, and devices for reducing overhead messaging such as event-driven LSAs in networks are disclosed. Embodiments of such systems, methods, and devices generate a simplified link-topology map from a comprehensive link-topology map. The comprehensive link-topology map is representative of the links among a plurality of networked satellite-traffic terminals (STTs). Embodiments of such systems, methods, and devices also generate, based at least in part on the simplified link-topology map, an STT-specific set of link state advertisement (LSA)-transmission instructions for each STT in the plurality. At least one such set of LSA-transmission instructions directs the corresponding STT to transmit LSAs on less than all of the links that extend in the comprehensive link-topology map from the corresponding STT. In addition, embodiments of such systems, methods, and devices also transmit the respective sets of LSA-transmission instructions to the respective STTs for which said sets were generated.

Abstract: Systems, devices, and methods are disclosed for determining link performance metrics for satellite communication terminals. Using link performance metrics and link performance difference metrics, signal modulation and coding may be decided. Link performance metrics may be determined for individual terminal uplinks and downlinks. Fixed and dynamic link adaptation mechanisms are also disclosed that utilize link performance metrics and link performance difference metrics determined under clear sky and dynamic conditions.
