Abstract:
1. A method of managing resources implemented in a resource manager for a satellite telecommunication system including a plurality of user terminals sending data to spots via a satellite, all data streams from a given terminal to the same given destination spot constituting a virtual path comprising a set of uplinks from said terminal to said satellite and a set of downlinks from said satellite to said spot, said manager including a central entity associated with said satellite and including means for receiving requests sent by said user terminals, each request expressing a requirement to use resources of the satellite which correspond to said virtual path, wherein said central entity comprises: means for grouping said requests into request groups each associated with a set of uplinks from the same spot to said destination spot, said set of uplinks constituting a virtual link, said same spot including terminals of said plurality of user terminals of said communication system; and means for determining authorized resources for each request group; which method includes: a first step of distributing a portion of said resources of said satellite associated with said downlinks used by said downlink streams to the same spot between said virtual links associated with said same spot as a function of a weighting parameter associated with each virtual link in order to generate authorized resources associated with each virtual link; and a second step of distributing said portion of said resources of said satellite associated with said uplinks used by said uplink streams from the same spot between said authorized resources associated with said same spot as a function of a weighting parameter associated with each of said authorized resources so as to generate modified authorized resources associated with each of said authorized resources.
