Integrated QoS, Energy-Aware Traffic Engineering, and Weather-Resilient Optical Downlink Scheduling for LEO Satellite Networks

Integrated QoS, Energy-Aware Traffic Engineering, and Weather-Resilient Optical Downlink Scheduling for LEO Satellite Networks

Abstract:

Low Earth orbit (LEO) mega-constellations are becoming a key component of the future Internet, offering global coverage and supporting applications with diverse performance requirements. Managing traffic in these dynamic networks requires approaches that consider routing, quality of service (QoS), energy efficiency, and environmental factors. Advances in QoS-aware routing, green segment-routed traffic engineering, and weather-resilient optical downlink scheduling show how LEO systems can better adapt to variable loads, heterogeneous QoS demands, and adverse conditions. We divide the presentations in three parts focusing on QoS-driven, energy-aware, and weather-resilient traffic management in LEO satellite networks as follows:

Part I: Topology-Aware and QoS-Driven Traffic Management in LEO Satellite Networks

Part II: Green Traffic Engineering for Satellite Networks using SRv6, Flex-Algo, and SDN

Part III: Optical Downlink Scheduling in Adverse Weather Conditions for Delay-Tolerant Sparse Satellite Constellations.
