Hi everyone, Now I wanto usnetem to simulate a delay just for a single packet(i.e. 2 th) to tesre-transmission featurof tcp. I know netem can use u32 filter to match iwith a delay action. However, icannot distinguish the first onand thsecond re-transmitting one as they are exactly same. How can netesimulata delay just based on the order situation ? For example, firspackedelay 5ms, second re-transmitting one delay 10ms, third re-transmitting ondelay 15ms ? Any idea is appreciated. Thanks a lo! -- BesRegards, Wei -------------- nexpar-------------- AHTML attachmenwas scrubbed... URL: <http://lists.linuxfoundation.org/pipermail/netem/attachments/20141027/ce7f8c4b/attachment.html>
