Abstract
A constellation of satellites provides communication services to user terminals (UTs). Downstream data addressed to a UT is received at a point-of-presence (POP) and tokenized before sending to a satellite serving the UT. Tokens are associated with resource blocks (RBs), each RB indicative of a particular combination of downlink frequency and timeslot. Tokens are then allocated to downstream data. This tokenized downstream data is sent to the satellite. Untokenized downstream data may be buffered for later tokenization or discarded. A satellite may use information in the token to schedule transmission on a downlink to the UT. The supply of tokens may be based on shaper input data such as gateway queue depth, estimated latency from the POP to the satellite, estimated time to empty a buffer onboard the satellite, and so forth. The supply of tokens may be adjusted to minimize data loss during handovers from one satellite to another.
