The Adaptive Voice/Data Networks Project
University of Kansas
Narrowband integrated voice/data networks require that congestion
control and bandwidth management techniques be implemented in order to
provide the desired quality of service. In this project, we exploit the
capabilities of the Sinusoidal Transform Coder (STC), a low bit-rate
digital speech coder, to address these requirements. An adaptive
voice/data switch has been developed to support these investigations.
The switch allocates bandwidth based on its load, and performs
adaptive rate transformations on the coded speech to trade quality
versus channel availablity. The unique features of the coding scheme
and the control algorithms allow for efficient and flexible bandwidth
usage, particularly under conditions of high load.
This research is supported by Rome Laboratories under
contract F30602-93-D-0075, subcontract C/UB-1754-D.
