A satellite communication system includes a global bandwidth enforcer that allocates bandwidth from the global bandwidth pool in accordance with a group service plan having a predetermined geographic scope. The system further includes an allocation of bandwidth from the one or more channels of the one or more beams of a first satellite in accordance with the group service plan. The system further includes a second satellite access station that receives an allocation of bandwidth from the one or more channels of the one or more beams of the second satellite in accordance with the group service plan. The system further includes a first sub-network associated with the first satellite access having a coverage area in the predetermined geographic scope of the group service plan, where the first sub-network receives an allocation of bandwidth from the first satellite access station in accordance with the group service plan.

An on-line fault detection and avoidance method is provided for industrial control systems that include multiple interacting process controllers. The method addresses the problem that not all faults can be determined and removed at the time of system design and testing. When a fault translates into a time-out condition in one or more controllers, symptoms are identified, persistence is measured, other involved controllers are identified, the fault condition is identified and control laws are reconfigured to avoid the fault condition in the future.
