I happened to have done a string of test runs of the rrul test against a very complex network with multiple wifi paths mostly against the main babel (with diversity routing on, but the smoothing code is not part of quagga which was running on a few of the nodes) the other day. I generally get "interesting" behavior when I load it up for longer than 60 seconds. I used a beaglebone black on the other side of the connection, and a variety of other boxes in the loop for the wifi side (cerowrt wndr3800s, picostation 2HPs),
These two tests exercised all 4 wifi queues: http://results.lab.taht.net/120s_NoOffloads_BQL1500_IPv6_Atoms_wifi_beagle-20281/120s_NoOffloads_BQL1500_IPv6_Atoms_wifi_beagle-fq_codel-all_scaled-rrul.svg http://results.lab.taht.net/120s_NoOffloads_BQL1500_IPv6_Atoms_wifi_beagle-20281/120s_NoOffloads_BQL1500_IPv6_Atoms_wifi_beagle-pfifo_fast-all_scaled-rrul.svg You can see how badly BE and Background traffic compete against video and voice traffic under 802.11e on adhoc mode presently. These just used one queue: http://results.lab.taht.net/120s_NoOffloads_BQL1500_IPv6_Atoms_wifi_beagle-20281/120s_NoOffloads_BQL1500_IPv6_Atoms_wifi_beagle-codel-all_scaled-rrul_noclassification.svg http://results.lab.taht.net/120s_NoOffloads_BQL1500_IPv6_Atoms_wifi_beagle-20281/120s_NoOffloads_BQL1500_IPv6_Atoms_wifi_beagle-fq_codel-all_scaled-rrul_noclassification.svg In both sets of cases there was some sort of massive switch in routing late in the test... the netperf-wrapper scripts (rrul and rrul_noclassification) were used in conjunction with netperf 2.6 for these tests. https://github.com/tohojo/netperf-wrapper requires python to drive the test and python-matplotlib to do the plotting. Example line: netperf-wrapper -l 120 -H the_other_host -o mytestplot.svg -p all_scaled rrul There are also simpler tests like tcp_bidirectional, and more complex ones that test ipv6 against ipv4, etc in the same test suite. -- Dave Täht Fixing bufferbloat with cerowrt: http://www.teklibre.com/cerowrt/subscribe.html _______________________________________________ Babel-users mailing list [email protected] http://lists.alioth.debian.org/cgi-bin/mailman/listinfo/babel-users
