Abstract: A multibeam is configured to transmit a duplicate of a channel from one spot beam in another spot beam, which contains a remote monitoring station. The satellite is reconfigurable to select the channel which is duplicated, allowing the beams of the satellite to be monitored, without the need for a remote monitoring station in each beam.
Abstract: In a TCP start protocol for a network including a link for which a minimum guaranteed transmission bandwidth has been negotiated, packets are transmitted at an initial rate that is inversely dependent on the guaranteed bandwidth, until an acknowledgement is received from the receiver. In this way, congestion in the link is avoided and transmission performance is improved.
