Hello!
Well I won't go into protocol details, but
I do not care if an intra-domain node will be
congested via packets on ingress. I will drop them,
but check with "tc .. show .." how much I get on
byte-level. Based on this, and maximum egress
transmission rate of this congested node, I calculate
Overload%, and remark leaving packets at that ratio.
OK I guess you know what you want - just thinking there wouldn't be much
overload% if tcp was about and you were dropping.
Anyway this setup will serve as a demo, having
reservations thoughout the domain for UDP video packet
streams only.
I wrote to netdev-linux mailing list about how to hack
in the sources of tc something like:
for every packet
if(rand()<(percent/100))
do_action
,where rand() gives a float of 0..1
If that's userspace tc it may be OK - no floats in kernel code AFAIK.
Could you point me to someone who will probably help
me with this?
I think netdev is the right place.
Andy.
