Abstract
A method and system within a telecommunications network for allocating available bandwidth among a plurality of sessions that share a common data link. First, a repeating unit time interval is designated for conducting the plurality of sessions. Next, the input flow rate from the source node of each of the sessions into the common data link is monitored. Thereafter, a target flow rate is computed and assigned to each of the sessions. The sum of the target flow rates is equal to the available bandwidth of the common data link. Finally, for each of the sessions in which the monitored input flow rate exceeds the assigned target flow rate, the source node is dynamically paused during each repeating unit time interval, such that the monitored input flow rate conforms to the assigned target flow rate for each of the sessions.
