I just ran some rrul tests, but I am getting a strange behaviour. Setup: server -- delay -- mbox -- client netserver 50ms/50ms 45/900mbit cli: https://drive.google.com/open?id=10CwMwLItL6bVSyMTp8-kVXWuFBAG6ft2 1) ./vsetup.sh (includes vcake.sh) 2) ip netns exec server netserver 3) ip netns exec client flent .... rrul1 flent: https://drive.google.com/open?id=1XB1k68fv4PCsRhSbmbCMvqOLk7Dv08bh rrul1 tc qdisc show: https://drive.google.com/open?id=1mKEYq7iDauOL5A9lCat_jAUgE7Eq6et8 rrul2 flent: https://drive.google.com/open?id=19OhJdOtMLcsNM66Jy-Edn7rD8TC9WelJ rrul2 tc qdisc show: https://drive.google.com/open?id=1HtgjwvmTbr7XQKRp4XOqVvkz8FzCxdTk rrul1 looks good, while rrul2 has a very strange trace. Look at the upload/ping. The setup was exactly the same between these two. If I lower the mbox bandwidth to 10/200mbit I don't get this behaviour anymore, the traces look like rrul1. Am I doing something wrong? George On Tue, Nov 28, 2017 at 7:20 PM, Georgios Amanakis wrote: > > > I got Dave's netns scripts working on my server.
