Abstract

Congestion control schemes in LANs interconnected by bridges are presented. The networks are assumed to support voice and data traffic through the use of prioritized media access control protocols. The proposed congestion control protocols throttle the data input traffic to the network using special feedback messages called choke packets, thereby dynamically allocating bandwidth to voice and data traffic in case of bridge overload. A simulation study has been carried out to demonstrate the feasibility and effectiveness of the proposed protocols. Simulation results have shown that the protocols yield higher bridge throughput efficiency for both voice and data traffic with minimum protocol overhead.
