Meeting summary --------------- * Roll Call (mtahhan__, 14:59:44) * Maryam Tahhan (mtahhan__, 14:59:50) * Agenda (mtahhan__, 15:01:28) * dev update (mtahhan__, 15:01:38) * QoS Readout (mtahhan__, 15:01:46) * Release D (mtahhan__, 15:01:57) * AOB (mtahhan__, 15:02:05) * dev-update (mtahhan__, 15:02:28) * bug fixes worked on as well as cli parameter updates (mtahhan__, 15:05:32) * LINK: https://gerrit.opnfv.org/gerrit/#/dashboard/self (mtahhan__, 15:05:39) * don't be afraid to merge +1'd code (mtahhan__, 15:05:52) * Moongen - latency testing is being worked in (mtahhan__, 15:06:06) * Moongen - running in a VM - work ongoing there (mtahhan__, 15:06:20) * as part of this effort - virtio drivers from master moongen branch have been merged with Bill's tree (mtahhan__, 15:07:17) * not published yet (mtahhan__, 15:07:31) * Bill is seeing packets getting dropped on the Receive side of the virtio ports into the VM on both his branch and the master moongen branch (mtahhan__, 15:08:33) * don't know if the moongen maintainers are aware of the latency bug that exists (mtahhan__, 15:10:28) * github issue will be opened against the repo (mtahhan__, 15:10:41) * 2889 address caching and learning tests still under testing (mtahhan__, 15:12:28) * Sridhar looking at Yardstick support from the yardstick. (mtahhan__, 15:12:48) * QoS Testing Readout - Sridhar (mtahhan__, 15:13:40) * ACTION: - Sridhar to send link to "An internet-wide analysis of Traffic policing" paper to the mailing list (mtahhan__, 15:15:02) * ACTION: Sridhar to upload readout to the readouts wiki (mtahhan__, 15:15:32) * Sridhar walking though how to setup QoS for OVS (mtahhan__, 15:15:51) * OVS doesn't implement QoS itself (mtahhan__, 15:16:27) * it uses a subset of Linux Kernel QoS features (mtahhan__, 15:16:48) * Policing works as expected (mtahhan__, 15:17:32) * traffic shaping is a possible test case that we could look at benchmarking (mtahhan__, 15:17:56) * Al points out that if OVS vsctl is using tc to configure the queuing - then the queuing is happening on the Linux Plane not the vswitch plane (mtahhan__, 15:23:16) * then the testing would really be of the Linux Kernel Queue (mtahhan__, 15:24:14) * Al points out that there is a traffic management benchmarking rfc - 7640 that we might be able to leverage (mtahhan__, 15:24:55) * LINK: https://tools.ietf.org/html/rfc7640 (marst, 15:27:16) * Release D planning (mtahhan__, 15:27:36) * goals for moongen - latency testing, CI integration (mtahhan__, 15:34:38) * Al suggests that maybe RFC5481 can be implemented with moongen (mtahhan__, 15:35:04) * Q. if there's a limit on samples, how many samples can you get? (mtahhan__, 15:35:23) * 800/900 per second (mtahhan__, 15:35:35) * it may not be enough (mtahhan__, 15:35:47) * adding more options for tuning to vsperf (mtahhan__, 15:36:12) * binding options, profiles, moving to libvirt instead of Qemu, adding testpmd 16-07 as a switch (mtahhan__, 15:36:57) * are some options (mtahhan__, 15:37:09) * vsperf integrated in a more openstack env (mtahhan__, 15:37:38) * Yardstick integration. (mtahhan__, 15:39:15) * IMIX testing is also something that could be implemented for D (mtahhan__, 15:41:50) * 40Gb integration is also an option for D (mtahhan__, 15:44:34) * Netronome would like to contribute back to vsperf the following features: NIC integration for 40Gb and 25 Gb. Moongen support for Netronome NICs, Drop rate tolerance and traffic patterns (mtahhan__, 15:47:49) * Moongen changes are in the master moongen branch (mtahhan__, 15:48:27) * compilation changes to DPDK for the NICs aren't upstreamed to Moongen yet (mtahhan__, 15:48:56) * ACTION: Bill to look Moongen feature planning for D next week (mtahhan__, 15:53:35) * ACTION: Maryam to to the same for yardstick (mtahhan__, 15:55:08) * Christian - vsperf tuning and options (mtahhan__, 15:55:32) * Prevaze - Netronome features (mtahhan__, 15:56:05) * review IMIX stories already in JIRA (mtahhan__, 15:56:42) Meeting ended at 15:57:36 UTC.
