Below examples were performed with two servers connected back-to-back with no router in between to rule out any blockage (they connect using an ethernet switch with ports in the same Vlan). `$ flent rrul_var -H 172.16.1.40 --test-parameter bidir_streams=6 --test-parameter markings=11,13,15,17,19,21` Summary of rrul_var test run from 2020-12-17 21:34:16.260047 Ping (ms) avg : 2.65 N/A ms 350 Ping (ms)::ICMP : 6.62 8.37 ms 350 Ping (ms)::UDP 0 (11) : 1.99 0.14 ms 350 Ping (ms)::UDP 1 (13) : 1.98 0.14 ms 350 Ping (ms)::UDP 2 (15) : 1.96 0.14 ms 350 Ping (ms)::UDP 3 (17) : 2.00 0.14 ms 350 Ping (ms)::UDP 4 (19) : 2.00 0.14 ms 350 Ping (ms)::UDP 5 (21) : 1.99 0.14 ms 350 TCP download avg : 156.53 N/A Mbits/s 350 TCP download sum : 939.18 N/A Mbits/s 350 TCP download::0 (11) : 190.43 171.36 Mbits/s 350 ---> OK TCP download::1 (13) : 166.60 170.35 Mbits/s 350 TCP download::2 (15) : 143.99 156.95 Mbits/s 350 TCP download::3 (17) : 171.11 170.65 Mbits/s 350 TCP download::4 (19) : 110.92 94.05 Mbits/s 350 TCP download::5 (21) : 156.13 0.01 Mbits/s 350 TCP totals : 939.87 N/A Mbits/s 350 TCP upload avg : 0.12 N/A Mbits/s 350 TCP upload sum : 0.69 N/A Mbits/s 350 TCP upload::0 (11) : 0.19 0.18 Mbits/s 350 ---> No data TCP upload::1 (13) : 0.10 0.17 Mbits/s 350 TCP upload::2 (15) : 0.04 0.07 Mbits/s 350 TCP upload::3 (17) : 0.14 0.13 Mbits/s 350 TCP upload::4 (19) : 0.09 0.13 Mbits/s 350 TCP upload::5 (21) : 0.13 0.14 Mbits/s 350 Now, if we run a tcp_12up test, we see upstream traffic: Ping (ms) ICMP : 2.22 2.55 ms 350 TCP upload avg : 41.77 N/A Mbits/s 350 TCP upload sum : 501.25 N/A Mbits/s 350 TCP upload::1 : 38.43 38.24 Mbits/s 350 TCP upload::10 : 40.92 39.39 Mbits/s 350 TCP upload::11 : 42.97 41.55 Mbits/s 350 TCP upload::12 : 46.13 39.80 Mbits/s 350 TCP upload::2 : 46.77 44.63 Mbits/s 350 TCP upload::3 : 40.24 39.21 Mbits/s 350 TCP upload::4 : 40.75 40.54 Mbits/s 350 TCP upload::5 : 40.41 38.85 Mbits/s 350 TCP upload::6 : 42.30 40.38 Mbits/s 350 TCP upload::7 : 41.68 40.38 Mbits/s 350 TCP upload::8 : 40.70 39.47 Mbits/s 350 TCP upload::9 : 39.95 40.17 Mbits/s 350 Apparently, on bi-directional tests, upload traffic doesn't show, but if we run a Upsteram-only test, it works. Traffic graphs on port connecting the servers show that indeed there is not Upstream traffic during testing. Upload traffic must be present, otherwise how the second server is replying? Is there any way to make upload traffic show up on rrul testing? Thanks. -- You are receiving this because you commented.
