but i didn’t get sufficient info on this. In the mailing list, I came
across a mail which I have added below, speaking about a possible way to
measure the packet loss. What I would like to know is, whether there is any
test specific commands that can be used to measure the packet loss or it can be
measured only using the below said way? Please comment on this.<o:p></o:p></span></font></p>
