[e2e] TCP Performance with Traffic Policing

[Barry Constantine]

I'd have to look, I don't think so.

One thing I forgot to mention was the policer.

I used default Cisco settings, 10 Mbps CIR and bc = 312,500 bytes.

When I increased bc to max as suggested by Anil (1,000,000 bytes), the 64 KB scenario worked perfectly but 128 KB still poorly.

Thanks,
Barry

Hi Barry,

from a quick look of your Linux 64/128 dumps I would say your setup is broken.
The trace is highly bursty. Do you have a delay on the reverse path? I guess no...

Alexander,

I could not read your encrypted email.

I saw the email from the postel-moderator and assume the attachment did not go through.
