Intra-domain load balancing
First Claim
1. A satellite system for communication with a plurality of remote locations, the satellite system comprising:
- a satellite configured to transmit a plurality of service spot beams including forward channels;
a gateway configured to transmit a plurality of the forward channels, each of the plurality of forward channels being transported on a carrier in one of the plurality of service spot beams, at least one of the plurality of the forward channels being divided in time to form a plurality of forward sub-channels;
a plurality of satellite modems each configured to receive one or more of the plurality of forward sub-channels; and
a scheduler configured to allocate resources to the plurality of satellite modems over the plurality of forward sub-channels by adjusting a size in time duration of at least some of the plurality of forward sub-channels relative to each other.

Abstract
A satellite system for broadband communication utilizing load balancing of satellite modems between physical forward sub-channels. The bandwidth requirements of the various satellite modems allocated to a domain are analyzed. Satellite modems, which can be moved between various physical forward sub-channels, are moved among physical forward sub-channels of a plurality of domains to balance loading between domains and/or physical forward sub-channels within domains. Buffering and latency are monitored in the subscriber modem termination system (SMTS) to allow dividing physical forward channel delay either uniformly or according to tiers of quality of service.
