A congestion avoidance scheme for ABR services in an ATM satellite system is described. The scheme relies on the broadcast nature of a satellite system to control the rates at which user terminals can send their requests for capacity. The scheme is integrated with the uplink scheduler mechanisms and therefore it is capable of achieving high bandwidth efficiency. It also achieves fairness in satellite resource utilization, while guaranteeing low cell loss ratio with rather modest buffer size.

Broadcast rate control allocation (BRCA) for congestion avoidance in satellite ATM networks

A satellite data communication system and method of operating the same is disclosed. The satellite data communication system provides switched transport services for multi-media networks, wherein access schemes, protocols and switching techniques are combined to offer optimized dynamic bandwidth-on-demand on a cell-by-cell basis.
