Systems (100) and methods (900) for controlling distribution of media streams during a teleconference. The methods comprise: configuring, by a central controller (102), a media stream flow between user nodes (106-132) which are participating or are to participate in the teleconference based on one or more first parameters; periodically determining, by the central controller, an end-to-end latency for each pair of the user nodes during the teleconference; and dynamically re-configuring, by the central controller, the media stream flow between the user nodes participating in the teleconference in view of the end-to-end latencies which were previously determined. The media stream flow is configured/re-configured by ordering the user nodes into a daisy chain structure (300, 400), a tree structure (500, 600, 602) or a hybrid structure (700, 800). The structure in which the user nodes are configured can be different than the structure in which the user nodes are subsequently re-configured. |
