Integrated Planning and Execution for Satellite Tele-Communications

The next generation of communications satellites may be designed as a fast packet-switched constellation of spacecraft able to withstand substantial bandwidth capacity fluctuation ranging from unstable weather phenomena to intentional jamming of communication. We have designed and partially implemented an architecture for managing satellite telecommunations net- work resources. Our approach supports advance reservations and dynamic requests, negotiation and fulfilment of prioritized Quality of Service (QoS) contracts, graceful degradation in the presence of dynamic tasks and environn~ental changes, and optimization of geometrically constrained resources. Our integration of planning arid execution to address this task uses planning to avoid resource contentions among requested xtivities and to configure an independently competent cxccut~on system. Our system tan be used in routin? operat~ons or a? a simulation-based design tool.
