Meeting summary

  1. Development Update. (srao, 16:04:01)
    1. Al Morton (acm, 16:04:34)
    2. Timestamps to Log-files- Should we? (srao, 16:05:13)
    3. Adding timestamps doesn't hurt. Consolidation of logs can be taken in future. (srao, 16:06:46)
    4. Testapi Container running in Pod-12. (srao, 16:07:20)
    5. Add this config file: OPNFV_URL= http://10.10.120.22:8000/a (srao, 16:07:55)
    6. add this into config file: OPNFV_URL= http://10.10.120.22:8000/api/v1 (srao, 16:08:09)
    7. Include this when running the test: --opnfvpod intel-pod12 (srao, 16:08:28)
    8. Started to explore Cedric's XTesting - create ansible for Vsperf. Will update the team next week. (srao, 16:11:06)
    9. Started experimenting with newer versions of OVS-DPDK-VPP (srao, 16:14:14)
    10. Need to discuss gRPC & REST limits with Cedric. (acm, 16:14:36)
    11. DPDK 18.11, OVS 2.10, VPP 18.1.2 (srao, 16:15:17)
    12. Hari: We have to remove these flags '--burst=64 -i --txqflags=0xf00 ', if we move to DPDK 18.11 (srao, 16:18:10)
    13. : Support for libvirt. We have to move from qemu-system-x86_64 command to libvirt. (srao, 16:20:38)
    14. Why it helps to move to libvirt: (a) For short-duration we may not see any issues, however for longer durations there will be performance degradation. (srao, 16:21:44)
    15. qemu will eventually cause a few packets to drop with VPP (acm, 16:21:49)
    16. estimate of 3 weeks development time (acm, 16:22:10)
    17. Why it helps to move to libvirt: (b) CPU pinning would be relatively easier (srao, 16:23:00)
    18. if we move to libvirt, the XML will tell qemu how to start, handled much more efficiently (acm, 16:23:04)
    19. Christian - With DPDK 18.11 We may have to enable legacy-memory option (--legacy-mem) (srao, 16:24:02)
    20. DPDK 18.11 might have to add legacy memory option, otherwise will see drops (acm, 16:24:05)
    21. Hari: --burst=64 i is still included, whereas disable-hw-vlan is not (srao, 16:24:30)

  2. Tipsy presentation (acm, 16:29:56)
    1. Peter and Felician will supply slides for posting in the read-out section of our Wiki ?? (acm, 16:57:17)
    2. t4p4s is the P4 switch, pronounced "tapas" (acm, 16:58:06)
    3. IEEE JSAC Dec 2018 paper describes the tool (acm, 16:58:55)
    4. performance results for lagopus and t4p4s were quite low. (acm, 17:00:53)
