With the proliferated low-Earth-orbit (LEO) satellites inmega-constellations, the future Internet will be able to reach any place onEarth, providing high-quality services to everyone. However, high-qualityoperations in terms of timeliness and resilience are lacking in the currentsolutions. This paper proposes a multi-layer networking approach called"Cross-Layer Descent (CLD)". Based on the proposed system model, principles,and measures, CLD can support foundational services such as telecommand (TC)transmissions for various network operation missions for LEO satellitescompliant with the Consultative Committee for Space Data Systems (CCSDS)standards. The CLD approach enhances timing and resilience requirements usingadvanced communication payloads. From the simulation-based analysis, theproposed scheme outperforms other classical ones in resilience and latency fortypical TC missions. The future work and conclusive remarks are discussed atthe end.
