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

* Brady Johnson  (ebrjohn, 16:59:39)

  agenda  (ebrjohn, 17:00:14)
* Diego Granados  (dgranados, 17:00:22)
* Sam Hague  (shague, 17:04:57)
* Brady talking about the context of this meeting. The implications of
  implementing SFC not on NSH, but on VXLAN  (edavsua, 17:06:38)
* Ericsson has plans to use plain VXLAN, but not abandon NSH  (edavsua,
  17:08:15)
* we need to re-classify, since we are not going to have the NSH
  metadata at hand  (edavsua, 17:08:59)
* VXLAN has some scalability limitations, but it is widespread
  (edavsua, 17:09:30)
* We can use a flag on the SF model  (edavsua, 17:10:00)
* Ericsson will continue supporting NSH, this is just a workaround until
  we have "official" support in OVS  (edavsua, 17:10:37)
* M2 milestone is comming in a couple of weeks. So we need to have a
  plan in place for that date  (edavsua, 17:11:24)
* Jaime, Diego and the rest of the Ericsson's team are working on the
  integration of SFC with Genius  (edavsua, 17:12:28)
* The integration with Genius is done in the context of the Logical SFF
  (edavsua, 17:13:13)
* Jaime tells we are just finishing the feature, even the classifier
  integrated with Genius  (edavsua, 17:13:44)
* We still need to migrate the sfc-genius component to blueprint
  (edavsua, 17:14:15)
* we haven't done any major changes in the current model of the
  classifier  (edavsua, 17:14:52)
* the classifier finds out the neutron port for the data plane node
  where to send the traffic  (edavsua, 17:16:04)
* the model remains the same  (edavsua, 17:16:17)
* Sam, how are we going to reclassify using the VXLAN?  (edavsua,
  17:17:28)

  Daya's response where she says SFC can remove the NSH header
  (ebrjohn, 17:19:23)
* Jaime: the classifier is a higher priority service that comes after
  SFC  (edavsua, 17:20:42)
* Sam: Genius will handle the metadata doing the same type of work we
  are doing noe  (edavsua, 17:21:17)
* Jaime: can the classifier handle the use case in which the VM migrates
  (edavsua, 17:21:59)
* Jaime: we are working on that now in the context of the Logical SFF
  (edavsua, 17:22:34)
* Sam: right now we are adding all the rules needed on all the nodes
  where the client might migrate to  (edavsua, 17:24:45)
* Jaime: does this mean that the Classifier is located always in the
  first SF?  (edavsua, 17:26:40)
* We have a VXLAN-GPE on every node right now  (edavsua, 17:27:27)
* the client should be outside the SFC domain  (edavsua, 17:27:48)
* within the Logical SFF we assume that Netvirt is creating the
  transport zones beforehand  (edavsua, 17:29:51)
* This is for Carbon  (edavsua, 17:30:39)
* Non-NSH is for Carbon as well  (edavsua, 17:31:22)
* we need to continue using the old-netvirt  (edavsua, 17:32:15)
* Ericsson's priority will be the Non-NSH for Carbon  (edavsua,
  17:33:51)
* SFC will be integrated with Genius and using either NSH or VXLAN as
  transport, but reusing the same code as much as possible  (edavsua,
  17:34:53)
* we'll cancel the meeting of next week  (edavsua, 17:38:39)
* can we code all the current metadata (NSP and NSI) in the VNI?
  (edavsua, 17:39:54)
* we can use one of the first tables (ingress) to load registers with
  the VNI to be used later in the pipeline  (edavsua, 17:41:07)
* we'll have limitations in the number of service functions due to the
  limited amount of bits  (edavsua, 17:42:25)
* Eric: how are we going to differentiate the NSH and the Non-NSH in the
  model?  (edavsua, 17:43:59)
* we'll have different transport flag  (edavsua, 17:44:31)



Meeting ended at 17:45:55 UTC.
