METHOD FOR DYNAMIC BACKUP OF CAPACITY OF RETURN CHANNELS IN INTERACTIVE ACCESS SATELLITE COMMUNICATION NETWORK

摘要

FIELD: radio engineering, communication.;SUBSTANCE: method involves measuring in each active satellite terminal the rate of packet data traffic from terminal equipment and the occupation of the input buffer of the satellite terminal in periods of time that are multiples of the super-frame duration; determining the optimum value of the quantile level for predicted values of the rate of packet data into the satellite terminal buffer one, two and three super-frames ahead; generating a request for dynamic backup of capacity taking into account QoS requirements based on the occupation of the input buffer and requests generated at previous super-frames, as well as packet traffic rate prediction data, carried out taking into account the quantile level characterising backup redundancy.;EFFECT: dynamic backup of return channel capacity resource, which enables to increase network efficiency in conditions without traffic overload due to minimal redundancy of capacity backup while meeting requirements for average delay and delay jitter for transmitted RBDC traffic packet data, to which VoIP and video conferencing traffic relates.;6 dwg
