Rapid Flow with 500M Udp Cross Traffic

If valid excursion=4 and gap threshold = 10000 is used to run rapid competing with cross traffic, Rapid is always unable to detect cross traffic and enters the pattern that throughput keeps increasing till 1Gbps and spend a long time in loss recovery after packet losses. So to run this experiment, valid excursion=4/8 and gap threshold=1000/3000.

Analysis of gaps and ABests for experiment(4):

For the 4 sets of experiments, there are less than 150 pstreams got logged for each set. And only in experiment 3/4, highest probing rate exceeds the available bandwidth which is around 480Mbps. So experiment 4 is chosen to be studied. When highest probing rate for a pstream exceeds 500Mbps, the recvgaps experience lots of spikes with valleys in between:
For pstream 100:


For pstream 140:


For pstream 145:

To get the cdf of all recvgap and sendgaps:

Try both exponential smoothing with alpha=0.875 and spike to spike averaging:

For pstream 140:


For pstream 145:



If the original prune stream is filtered by exponential or arithmatic averaging after spike-to-spike averaging, the new pruned streams will be as follows: (the first plot shows the original pruned gaps, the second plot shows the pruned gaps processed by spike-to-spike averaging and arithmatic smoothing with avg_size=8, the third plot shows the pruned gaps processed by spike-to-spike averaging and exponential smoothing with alpha=0.875)

Another experiment: pstream length= 80 valid excursion= 8 gap threshold= 3000 arithmatic averaging 8
