(54) | Data flow control method |
(57) A method of controlling the flow of an amount of data from a sending peer to a receiving
peer of a predetermined communication protocol is described. The method comprises
dividing the amount of data into a plurality of data segments, where the data segments
are ordered in a sequence. The segments are sent to the receiving peer in the order
of said sequence. The receiving peer acknowledges the correct receipt of a data segment
and identifies the last correctly received data segment of the sequence that was received
in the proper order of the sequence. The sending peer is arranged such that if it
receives a threshold number of duplicate acknowledgements, it performs a retransmission.
The threshold number that trigger a retransmission is an adaptive parameter and may
assume values larger than three. |
