Subject: [LARTC] How do you know that traffic control is in place???
Date: Tue, 27 Mar 2001 11:39:25 +0000	[thread overview]
Message-ID: <marc-lartc-98569266006062@msgid-missing> (raw)

Hi all,
I've tried quite a lot of different tc configurations.

One of the key problem is how to graph the network traffic from a saved text
file in order to show that PRIO works, CBQ works, etc...

I have tried tcpdump and then use tcpstat to graph my results. But the
results were grossly out!!! I then tried Tele Traffic Tapper and found that
it tallies with my tc configuration!!

I am not sure what TTT is using to sniff but apparently after i tcpdump to a
file and then read off with TTT, it is grossly out again!! this implies
either tcpdump not working properly or that during the writing of the data
to a file, the time taken is significant!!

TTT doesn't saved its data into a file. Instead it just graphs it... prob
that's why!

I'm really anxious to know what tools are you guys using to graph your
results???


Regards.
