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

* Development Update  (SridharRao, 15:02:14)
  * Xena-Patch from Christian/Bob multi-flows is merged.  (SridharRao,
    15:03:10)
  * Logging Support VSPERF - Should Timestamps be added?  (SridharRao,
    15:04:01)
  * Timestamps should be added.  (SridharRao, 15:06:38)

* Pod-12 Status  (SridharRao, 15:07:16)
  * Al Morton  (acm, 15:07:20)
  * Intel Pods IP (new) We are back online at 192.55.66.214 with the
    exception of traffic generator.  (acm, 15:08:43)
  * Rerun Tests with Timestamps enabled in logs.  (SridharRao, 15:11:42)

* VSPERF-Intel Demo IEEE SDN-NFV  (SridharRao, 15:13:23)
  * Create Cache Profiles - L3 Cache.  (SridharRao, 15:14:02)
  * Find a test VNF that is cache-hungry [ Data-plane VNFs - AVB,
    Video-Servers, TGen-10G-64B]  (SridharRao, 15:14:54)
  * 35-55MB of L3-Cache per socket  (SridharRao, 15:17:18)
  * Experiment Test-VNF and Noisy-Neighbor - without dedicated cacheways
    (SridharRao, 15:18:51)
  * Repeat experiment with dedicated cacheways  (SridharRao, 15:19:04)
  * OS Nova cannot balance load across NUMA Nodes (Alec)  (acm,
    15:23:34)
  * No OS on Pod 12  (acm, 15:23:56)
  * Need Pod 19, where there will be a full OS and OPNFV Deployment,
    then NFV Bench  (acm, 15:24:44)
  * Alec - multiple instances of Testpmd  may be sufficient to consume
    cache  (acm, 15:26:00)

* Container-Networking - Vswitch-Based Only ?  (SridharRao, 15:26:32)
  * Many options, and K8s adds even more networking options!  (acm,
    15:27:35)
  * Sridhar - Should we focus on vSwitch scenarios?  (acm, 15:28:32)
  * Alec - first decision is to use K8s or not  (acm, 15:28:51)
  * SR - Assume no K8s, just Docker Containers, is this worthwhile place
    to start?  (acm, 15:29:45)
  * vSwitch would be running on baremetal  (acm, 15:30:19)
  * Christian - not plugged-in yet, need to ask RH perf team, get some
    input  (acm, 15:31:05)
  * (1) Presentation on VSwitch-Based Container Networking.
    (SridharRao, 15:31:15)
  * Need info on common use cases today  (acm, 15:32:18)
  * Kubernetes + vSwitches:  Solutions/Studies existing  (SridharRao,
    15:32:35)
  * Alec - K8s only understands L3, is IP based, no L2 with vSwitch,
    SR/IOV is working for containers, too.  (acm, 15:34:08)
  * Alec - Intel and VPP/FD.IO have studies on Kubernetes+vSwitch
    (SridharRao, 15:34:51)
  * Alec - K8s uses TCP/IP stack in host, and there are some scaling
    issues when using many containers  (acm, 15:35:34)
  * #info Alec - experiments running TCP/IP stack in user space, with
    VPP?, with container connectivity at L3  (acm, 15:37:09)
  * ACTION: Alec627 to send FD.io doc on container networking  (acm,
    15:40:31)
  * acm agree  with this path, also learn from what others have done
    when measuring in this space.  (acm, 15:44:25)
  * Alec - L3 today in K8s, but this is not efficient when connecting
    multiple containers.  (acm, 15:51:49)



Meeting ended at 15:58:08 UTC.
