Dynamic Bandwidth Allocation and Congestion Control Schemes for an Integrated Voice and Data Multiplexing in Wideband Packet Technology

Bandwidth allocation is a critical issue in a statistical multiplexer for packetized voice and data. The statistical multiplexer should make efficient use of the transmission bandwidth while meeting the performance (e.g., delay and packet loss) requirements for all traffic types. We describe here a (T sub 1, T sub 2) - scheme which efficiently integrates packetized voice and data traffic. Voice and data packets are queued separately, and the (T sub 1, T sub 2) - scheme is used to facilitate dynamic bandwidth sharing and mutual overload protection between the two queues. T sub 1 and T sub 2 are time limits for transmitting voice and data packets continually while the voice and data queues are visited alternately.
