Abstract

Upstream information at a user terminal in a satellite network is efficiently scheduled through a Demand Assigned Multiple Access (DAMA) algorithm that delays transmission of the first packet's bandwidth allocation request in order to allow subsequent packets to be included in the first packet's bandwidth allocation request (up-front delayed concatenation) in order to minimize delay due to the long round trip time and overhead in packet processing and packet transmission through a hardware queue. Rather than merely the size of the next packet, the size of the entire concatenated frame is communicated to the scheduler, which may be distributed between the user satellite modem and the gateway, to prepare the schedule, where the schedule is the basis of the upstream transmission of the various associated user terminals. Optimal delay is a function of traffic pattern and the scheduling delay including round-trip delay.
