Meeting summary
---------------

* Al Morton  (acm, 15:04:06)
* delay histogram, upgrades CI hosts, feedback from IETF BMWG on the
  test results  (acm, 15:08:23)
* upgrades to CI  (acm, 15:09:14)
  * Centos 7.3 image upload/install on sandbox, no difference to Tput.
    (acm, 15:10:02)
  * Chris - there is an unknown source of packet loss, will investigate
    locally  (acm, 15:10:53)
  * Chirs never sees loss anymore - current status is in JIRA 518  (acm,
    15:11:45)

* delay histogram  (acm, 15:12:16)
  * Al's feedback on the list  (acm, 15:15:14)
  * no generic historgarm config for the T-gens  (acm, 15:21:29)
  * acm thinks they should be the same.  (acm, 15:23:50)
  * ACTION: sridhar generic config for generator histogram collection
    (acm, 15:26:22)

* stress-ng test case proposal  (acm, 15:27:57)
  * new noisy neighbor (_nn) test case with 2544 tput  (acm, 15:29:52)
  * need many VMs, sridhar looking for a place to put VNF images  (acm,
    15:30:25)
  * stress-ng is created to cause a particular sort of load/noise, and
    generates when it is spawned  (acm, 15:31:50)
  * mars - the right place may be OPNFV artifacts directory  (acm,
    15:32:29)
  * mars - naming of test cases is not very good, maybe _nn should be a
    prefix, not a suffix  (acm, 15:33:23)
  * ACTION: sridhar will send out test case proposal  (acm, 15:34:21)
  * sridhar shows the stress-ng configuration parameters and example
    (acm, 15:35:13)
  * author of stress-ng Collin King, at Canonical, very helpful, already
    added new feature  (acm, 15:37:36)

* VSPERF at IETF BMWG  (acm, 15:38:23)
  * question from BMWG - did you try IMIX??  (acm, 15:40:51)
  * answer - VSPERF is limited fixed packet sizes, and IMIX is a feature
    that benchmarkers would like to see  (acm, 15:41:42)
  * need a generic way to specify IMIX, that we can translate to all
    T-gens  (acm, 15:42:38)
  * yardstick may have the generic spec, also IMIX Genome spec  (acm,
    15:43:47)
  * ACTION: sridhar will look at YS IMIX and IMIX Genome RFC  (acm,
    15:44:16)
  * BMWG agree with more info on latency  (acm, 15:44:57)
  * Interest to refine the back 2 back frame testing - described the
    correction factor we used in Design Summit calculations  (acm,
    15:46:38)
  * if we want to reduce frame sizes used in b2b frame testing, need to
    feedback results from Tput tests  (acm, 15:48:22)
  * BMWG is re-chratering, taking-up new proposals NOW!  (acm, 15:49:37)

* next week  (acm, 15:51:49)
  * acm will not be able to join, away all week  (acm, 15:52:14)
  * no other business  (acm, 15:52:35)
