Abstract: The present invention relates to a system and method for dynamic allocation of a resource. In particular, it concerns a system to dynamically designate a priority for a resource request and to allocate a resource, partially filling or completely filling the request. Partial filling of requests and conditional priorities allows maximum use of resources at low priority while protecting minimum access to resources Thus, the system and method of the present invention improve access and optimization of a Bandwidth On Demand (BOD) satellite communication system. Free resources are used as access channelsthat may be allocated to a user.
Abstract: Method for managing power and bandwidth resources in operation over a plurality of links from a hub, said power and bandwidth resources being limited, the method comprising: initially assigning power and bandwidth combinations to individual links according to current conditions pertaining to respective links, each combination having a corresponding resource cost; and controllably changing said initially assigned combinations at respective ones of said links to reduce respective resource costs, thereby to controllably balance an overall resource cost of said plurality of links to lie within available overall power and bandwidth resource limitations.

Abstract: A satellite broadcasting system for communication between a satellite hub and a range of ground stations in which a set having a predetermined number of MODCODS is available for data transmission from the satellite hub to the ground stations. Each MODCOD in use in the hub requires additional hub resources, and the system uses a MODCOD limiter for limiting the number of MODCODs in operation at a given time to a subset smaller than said predetermined number of MODCODS, thereby reducing overall resource usage.
