Synchronization of TCP Flows
Mainly observed in simulation!
Compute distribution of number of consecutive losses
Approximation 2: consecutively dropped packets are dropped with same probability
Upper bound on number of consecutive drops
Accurate for smooth drop function and high load
Mean and variance of number of consecutive drops are lower with RED than TD
With queue size averaging, small weight, approximation 2 valid
No of consecutive drops is infinite with positive probability
RED results in higher mean and variance, which may lead to global synchronization
