A New TCP Congestion Control Mechanism for Differentiated Services
Rui Li · Acta Simulata Systematica Sinica · 2003
Differentiated services can provide different QoS for different user demands. TCP plays an important role in the Internet, but TCP抯 window-based congestion control algorithm impairs long RTT connections to achieve fair bandwidth share and support differentiated services, so researches on TCP congestion control for differentiated services is a meaningful job. This paper presents an active queue mechanism, EBLUE, and improves TCP congestion control algorithm. Then by combining two technologies, we investigate how TCP supports assured service and achieves fair bandwidth share among connections. The simulation results testify that our mechanism is feasible and fair.
