Abstract: A buffered packet switching network component provides a communication path between a packet source and a packet destination. The packet switching network component includes a bandwidth control mechanism that reduces communication traffic in response to buffer congestion. The bandwidth control mechanism is also utilized to conserve power. When the buffered packet switching network component detects a transition event, a parameter of the bandwidth control mechanism is modified such that a transferred packet indicates the packet switching network component is congested. In response to the congestion, a packet source is requested to reduce the rate at which it is sending packets through the congested packet switching network component. As network traffic is reduced, unused devices of the packet switching network component are deactivated such that power is conserved.

Abstract: A method and apparatus for steering beams modulated from a mobile platform in a manner that reduces overall platform payload processing, and therefore payload weight and power requirements. According to the present invention, a beam steering data calculator (64) generates a table of beam steering data sets (60a, 60b), with each data set corresponding to a specific beam-pointing angle mapped to a corresponding cell on the surface of the earth. A data set that corresponds to a received downlink cell address (22a-22e) is read out from the table and mapped to the downlink address, and an output angle of a modulated vehicle beam (16a-16e) that transmits a data packet to the cell address is corrected to correspond to the beam-pointing angle of the read-out data set.
