CONGESTION CONTROL PROTOCOLS FOR INTERCONNECTED LANS SUPPORTING VOICEAND DATA TRAFFIC

Congestion control schemes in LANs interconnected by bridges are prese nted. The networks are assumed to support voice and data traffic throu gh the use of prioritized media access control protocols. The proposed congestion control protocols throttle the data input traffic to the n etwork using special feedback messages called choke packets, thereby d ynamically allocating bandwidth to voice and data traffic in case of b ridge overload. A simulation study has been carried out to demonstrate the feasibility and effectiveness of the proposed protocols. Simulati on results have shown that the protocols yield higher bridge throughpu t efficiency for both voice and data traffic with minimum protocol ove rhead.
