Hi All,

We are doing some experiment, where we are trying to measure the processing time taken by a node when a packate pssess throgh it.

               --------eth0[Linux-PC Router]eth1-------

We run tethereal within this PC at eth0(incomming interface) and eth1(outgoing interface) . Then we find out our packate in  both the captures and the difference of two captures gives processing time of the node

Now, the question: Is doing so a right way to measure the processing time, as we are not sure where exactly does libcap captures the packates. Is it right before network driver or after it ao anywhere else?

Any help on this issue will be highly appreciable.

Thanks,

Nitin
