2011-06-30 Thread fernando farias

I would like to know if is there a mininet kernel image that works with debian 
squeeze?

because, current kernel image didn't install on debian squeeze, following the 
errors printed:

dpkg-deb: `linux-image-2.6.33.1-mininet_2.6.33.1-mininet-10.00.Custom_i386.deb' 
is not a debian format archive

Re: [nox-dev] Bandwidth Measurement.

2011-06-30 Thread Kyriakos Zarifis
Hi,

I think the closest thing that openflow can provide would be information
about how many bytes have been sent on one side and received on the other
side of a link.
So you could infer an approximation of active rates on the link by polling 2
neighboring switches from NOX at some regular intervals.
This can not be very accurate because there are factors like
round-trip-times for the requests/replies from NOX to the 2 switches and
back, these times will be different, also there are packets travelling
between the switches that should be taken into account etc.
But this is definitely a place to start if you want to do such measurements
from NOX.

The "monitoring" component on the destiny branch (netapps/monitoring) does
something like that (it regularly polls all switches for all kinds of
statistics), so it's a good place to look at.
