Subject: [Bismark-users] issues with slow-start.
Date: Wed, 06 Apr 2011 06:02:04 -0600	[thread overview]
Message-ID: <4D9C563C.4030206@taht.net> (raw)

The traces I took (of connecting to youtube) during yesterday's meeting 
at gatech were interesting.

Most of the problems with dropped packets, and reordering, I saw, 
appeared to occur during slow start!?!??

Here's an example:

WTF?

My thought is that there is either something wrong with my box, or the 
shapers you are using, or the wireless interface(s) I was connected to. 
Usually what I see is chaos AFTER a few seconds, not during slow start. 
(It's an otherwise normal tcp trace after it ramps up)

I'd like to re-run those tests using a few different interfaces and 
laptops to gain more insight into the problem.

Also somewhat related to this is if that if any other group(s) want some 
insight into the bufferbloat issue, I'm here, I have jg's slides, I can 
talk to it for an hour...

And similarly having at least one representative from the other group we 
met with yesterday on this list and the website would be good.
