Significant modifications were done to implement the rate-based congestion control framework. 1 A simple scenario with one traffic flow, one route and one congestion point. Link utilisation is good for all three. Round-trip times show effect of router queue lengths. Network Scenario 2 Several traffic flows and 1 congestion point.
Flows start at different times.
Optimal rates at any time can be calculated. RBCC rates extremely close to optimum rates. Network Scenario 5 Scenario 5 highlights unfair resource usage due to the spatial distribution of sources. No packets are lost. TCP Reno loses 405 packets.
