Hi folks,
I'm reading about this on the website:
"
The AQM layer has no configuration options. However, it is planned to add
simple tuning options for different prevailing RTTs that may be
significantly different from the Internet-scale 100ms currently assumed.
Satellite links tend to impose longer RTTs, and enclosed LANs tend to have
much shorter RTTs.
"
In Mauritius, and other african countries, we have RTT of around 300-400
ms. Could someone please point me to where I should look for adding a
tunable for this in the source files ?
Kind regards,
//Logan

I passed a partial patch around yestereday that almost but not quite
added support for the rtt parameter.

Hi Logan,
On 08/10/15 I pushed an 'exposeinterval' feature branch to both mine &
dave's sch_cake & tc-adv repos (so module & user side changes) which
exposed the interval (rtt) parameter. By the following morning it even
worked! On Morning of 11th Dave sent an email "adding 'rtt' support
correctly" to which I rather assumed my 'exposeinterval' branch was
superfluous, incorrect and unneeded so I removed them from Dave's repos
in the expectation of great things.
You'll still find my original versions of that branch
https://github.com/kdarbyshirebryant/sch_cake/tree/exposeinterval &
https://github.com/kdarbyshirebryant/tc-adv/tree/exposeinterval
A glance over Dave's patch suggests the only difference to the
'rtt/interval' side of things between his & mine is using nanoseconds in
the pass from user-space to kernel space rather than my use of milliseconds.
If you provide tc with a 'rtt 300ms' parameter it should work a treat.

They are now merged :-)
The TC code *really* needs looking at, it works but I really was never
any good at user interfaces!
