  2. GBP/SFC integration (tbachman, 16:04:54)
    1. alagalah says we’ve demonstrated dynamic chaining using policy (tbachman, 16:05:27)
    2. uses service function chain as an action, which goes to the next SFF, with SFCOFL2 dynamically creating flows (tbachman, 16:05:43)
    3. The OfOverlay renderer normally sends packets using VXLAN overlay; the chain action steers traffic to the SFF; to get from the last SFF back to GBP uses NSH type 1 metadata fields to preserve VNIDs and destination information (tbachman, 16:06:52)
    4. The final dest is kept in NSH C1 and the VNID is kept in NSH C2 (tbachman, 16:07:23)
    5. alagalah says they’ve been working on the neutron integration, where GBP, SFC are all done using neutron (tbachman, 16:07:54)
    6. alagalah says they’ve got distributed classification working just recently (tbachman, 16:08:16)
    7. alagalah says they’ve made some constraints for the Lithium release — today, only support uni-directional RSPs (tbachman, 16:09:50)
    8. ebrjohn asks how the packets get back? (tbachman, 16:10:02)
    9. alagalah says the reverse path uses the same chain, but this isn’t a symmetric RSP (tbachman, 16:10:41)
    10. alagalah says the next thing to test is multi-SFF (tbachman, 16:11:22)
    11. alagalah says they also need to look at directionality and coexistence (tbachman, 16:13:09)
    12. ebrjohn asks what the cutoff point is for the POC between Lithium and Beryllium (tbachman, 16:13:58)
    13. alagalah says as late as possible, provided stability (tbachman, 16:14:05)
    14. alagalah says they’re demoing SFC + GBP integration at CLUS, which is getting a good reception (tbachman, 16:15:29)
    15. alagalah says there are some folks working on putting together vagrant demos of SFC + GBP (tbachman, 16:16:22)
    16. ebrjohn would like to try to have a demo for next weeks’ call, but will be out of town Tues + Wed which may make that difficult (tbachman, 16:19:52)
    17. ebrjohn says Johnson Li got 7 votes; this will hopefully go to the TSC for a vote at today’s TSC meeting (tbachman, 16:21:07)
    18. ebrjohn and repenno started the SFC mentorship program; Shlomi from Contextstream has shown interest, and ebrjohn is acting as his mentor (tbachman, 16:21:46)
    19. ebrjohn is also mentoring ricky (tbachman, 16:22:01)


Meeting ended at 16:22:30 UTC (full logs).
