The twin-bus architecture for voice/data integration is discussed and a hybrid protocol for the data bus that combines CSMA/CD (carrier sense multiple access with collision detection) and announcement reservation schemes is proposed. To improve the performance on data bus, part of the bandwidth on the voice bus is used as the control subchannel for announcement reservation on the data bus. Simulation results show that the proposed hybrid protocol outperforms both CSMA/CD and the announcement reservation scheme in all cases. Since announcement reservation has good performance when traffic load is heavy, the combined protocol becomes efficient for both light and heavy loads.
