#opendaylight-sfc: weekly ODL SFC meeting

Meeting summary

1. 1. Brady Johnson (ebrjohn, 17:00:45)
   2. Diego Granados (dgranados, 17:01:38)
   3. Jaime Caamaño (jaicaa, 17:03:02)
   
   
2. Non-NSH encapsulation for SFC Carbon (ebrjohn, 17:05:19)
   1. Andre Fredette (afredette, 17:05:25)
   2. Ericsson will start working on a different alternative for NSH encapsulation than NSH (not abandoning NSH, just need something pure open source for its products) (dgranados, 17:08:01)
   3. Juanma Fernandez (juanmafg, 17:08:08)
   4. for that alternative, transport between classifier and the first SFF, and also in the transport trunk (i.e. between SFFs) will be vxlan (dgranados, 17:09:30)
   5. for traffic coming back from the SF to the SFF, the plan is to do reclassification (dgranados, 17:10:21)
   6. some discussion between afredette and ebrjohn follows on alternative ways (transport-based) to avoid/support reclassification (dgranados, 17:15:22)
   7. afredette describes a simple use case (virtual CPE) on which SFs only participate in one chain, allowing to avoid reclassification (dgranados, 17:18:49)
   8. this approach, given a working netvirt classificator, would uses vxlan VNIs in the trunk as SFC encapsulation (dgranados, 17:24:25)
   9. @ebrjohn mentions the possibility to incorporate that SF behaviour ("single-chain mode") to the model in the SF type (dgranados, 17:27:07)
   10. @juanmafg states that tricky details about this approach. Other protocols traffic (e.g. dhcp) would use the same service chain, and would end reaching SF's not really expecting it (dgranados, 17:31:41)
   11. https://wiki.opendaylight.org/view/Service_Function_Chaining:Carbon_Release_Plan SFC Carbon release plan (ebrjohn, 17:34:56)
   12. @afredette mentions a mechanism which uses different ports in the SF for handling multiple chains (dgranados, 17:37:23)
   13. ACTION: afredette will send the requirement to netvirt to support the vxlan transport/encapsulation (ebrjohn, 17:37:59)
   14. some discussion follows regarding the "single-chain mode" for SFs. It is clear that the main use case is virtual CPE (dgranados, 17:42:39)
