Method and system for communication session bandwidth control based on actual bandwidth usage

摘要

A method and system for allocating bandwidth among communication sessions are disclosed. In one embodiment, a method includes performing a first allocation to a first communication session and performing a second allocation to a second communication session. The method includes performing a reallocation of bandwidth from the first communication session to the second communication session based on a predetermined criteria.

1. A method for allocating bandwidth in a communications system that includes a plurality of user equipment, each of the plurality of user equipment being communicatively connected, during a communication session, to a multimedia collaboration server and configured to receive and transmit video and audio data, the multimedia collaboration server allocating a bandwidth to the corresponding communication session of each of the plurality of user equipment, the method comprising:
performing a first allocation of bandwidth to a first communication session; and performing a reallocation of bandwidth from the first communication session to a second communication session based at least in part on a criterion;
the criterion being a probability that an effective bandwidth of all communication sessions of the plurality of user equipment exceeds a threshold value;the effective bandwidth being bandwidth actually used;the probability being calculated based on an average of the effective bandwidth over time;an amount of bandwidth reallocated from the first communication session to the second communication session being a fraction of a difference between the first allocation and an effective bandwidth used by the first communication session before the reallocation; andthe effective bandwidth being associated with a mean value of a random variable and the first allocation being the mean value plus a multiple of a standard deviation of the random variable.
