ABSTRACT:
In a multipoint-to-point link, packets are transmitted over a shared medium to a central node in response to permits. The central node issues permits to a multipoint node on the basis of a queue size record, held at the central node. The queue record is updated on receipt of a queue size report (request for permits) from the multipoint node. Due to the transmission delays across the link, an erroneous queue value can be recorded at the central node when permits and a request for permits are sent at about the same time. This problem is overcome and the transfer capacity improved when the central node holds a record of the permits sent during the preceding round trip delay. Any incoming reqest for permits is then adjusted by the number of stored permits before it is utilized to update the queue record.
