Videoconferencing applications also have stringent QoS requirements very similar to voice. But videoconferencing traffic is often bursty and greedy in nature and, as a result, can impact other traffic. Therefore, it is important to understand the videoconferencing requirements for a network and to provision carefully for it.
The minimum bandwidth for a videoconferencing stream would require the actual bandwidth of the stream (dependent upon the type of videoconferencing codec being used) plus some overhead. For example, a 384-kbps video stream would actually require a total of 460 kbps of priority bandwidth.
