17:06:38 <edavsua> #info Brady talking about the context of this meeting. The implications of implementing SFC not on NSH, but on VXLAN
17:08:15 <edavsua> #info Ericsson has plans to use plain VXLAN, but not abandon NSH
17:08:59 <edavsua> #info we need to re-classify, since we are not going to have the NSH metadata at hand
17:09:30 <edavsua> #info VXLAN has some scalability limitations, but it is widespread
17:10:00 <edavsua> #info We can use a flag on the SF model
17:10:37 <edavsua> #info Ericsson will continue supporting NSH, this is just a workaround until we have "official" support in OVS
17:11:24 <edavsua> #info M2 milestone is comming in a couple of weeks. So we need to have a plan in place for that date
17:12:28 <edavsua> #info Jaime, Diego and the rest of the Ericsson's team are working on the integration of SFC with Genius
17:13:13 <edavsua> #info The integration with Genius is done in the context of the Logical SFF
17:13:44 <edavsua> #info Jaime tells we are just finishing the feature, even the classifier integrated with Genius
17:14:15 <edavsua> #info We still need to migrate the sfc-genius component to blueprint
17:14:52 <edavsua> #info we haven't done any major changes in the current model of the classifier
17:16:04 <edavsua> #info the classifier finds out the neutron port for the data plane node where to send the traffic
17:16:17 <edavsua> #info the model remains the same
17:17:28 <edavsua> #info Sam, how are we going to reclassify using the VXLAN?
17:19:23 <ebrjohn> #link https://lists.opendaylight.org/pipermail/sfc-dev/2016-November/003625.html Daya's response where she says SFC can remove the NSH header
17:20:42 <edavsua> #info Jaime: the classifier is a higher priority service that comes after SFC
17:21:17 <edavsua> #info Sam: Genius will handle the metadata doing the same type of work we are doing noe
17:21:59 <edavsua> #info Jaime: can the classifier handle the use case in which the VM migrates
17:22:34 <edavsua> #info Jaime: we are working on that now in the context of the Logical SFF
17:24:45 <edavsua> #info Sam: right now we are adding all the rules needed on all the nodes where the client might migrate to
17:26:40 <edavsua> #info Jaime: does this mean that the Classifier is located always in the first SF?
17:27:16 <edavsua> We have a VXLAN-GPE on every node right now
17:27:27 <edavsua> #info We have a VXLAN-GPE on every node right now
17:27:48 <edavsua> #info the client should be outside the SFC domain
17:29:51 <edavsua> #info within the Logical SFF we assume that Netvirt is creating the transport zones beforehand
17:30:39 <edavsua> #info This is for Carbon
17:31:22 <edavsua> #info Non-NSH is for Carbon as well
17:32:15 <edavsua> #info we need to continue using the old-netvirt
17:33:51 <edavsua> #info Ericsson's priority will be the Non-NSH for Carbon
17:34:53 <edavsua> #info SFC will be integrated with Genius and using either NSH or VXLAN as transport, but reusing the same code as much as possible
17:38:39 <edavsua> #info we'll cancel the meeting of next week
17:39:54 <edavsua> #info can we code all the current metadata (NSP and NSI) in the VNI?
17:41:07 <edavsua> #info we can use one of the first tables (ingress) to load registers with the VNI to be used later in the pipeline
17:42:25 <edavsua> #info we'll have limitations in the number of service functions due to the limited amount of bits
17:43:59 <edavsua> #info Eric: how are we going to differentiate the NSH and the Non-NSH in the model?
17:44:31 <edavsua> #info we'll have different transport flag
