Abstract
A packet network redistributes excess bandwidth for voice and data sessions applying a Quality of Service (QoS) algorithm. The network includes interacting client stations using H.323 protocol managing bit rate according to an algorithm as voice and data sessions are added or removed from the network. The client stations include codecs coupled to the network. The codecs provide voice sessions at a minimum bandwidth using a voice codec bit rate and preferred bandwidth using another voice codec bit rate. A first algorithm applies the QoS algorithm allocating bandwidth between interacting client stations after the addition of a new voice or data session when there is insufficient bandwidth for the new session to receive preferred bandwidth. A second algorithm is applied when a voice or data session is removed from the interacting client stations. If any session is allocated minimum bandwidth the QoS increases a voice session at minimum bandwidth to preferred bandwidth if excess bandwidth is available.
