Ryan,
I assume you are thinking about L3 VNF support?
If so yes I need to think this through - any ideas would be appreciated.

Based on Ryan's suggestions, here is my proposal for implementing the SFC
flowClassifier as ACLs. I wanted to get some feedback before I get into another
round of changes in the code.
Currently I have implemented SFC by adding a new table (ls_in_chain) in the
ova-stage of ovn-northd.c as follo
solutions and perhaps other approaches.
How would you like a VNF to behave to support multi-tenancy?

something work.
I am struggling with the "metadata" part that instructs the flow to skip the
rule in the ACL table. Is there some example code I can look at?

Ryan,
The flow-classifier rules need to have a lower priority than the ppg rules as
they steer the traffic into the chain. Therefore I could do this two ways:
1. I can put the flow-classifier rules

Ryan,
Trying to keep the thread to a single subject so we can knock them off.
There are two cases for multi-tenancy:
1. The VNF is multi-tenant: This implies that a single VNF can exist as a
port
re not important), I just have trouble juggling too many items
at the same time :-).
1. Agree on basic pipeline model/architecture
2. Resolve how to implement the FC/ACL model and implement
3. Resolve the M-T/S-T design
Thoughts?

Ryan,
Thanks for putting together the summary - I have a simple VNF case working with
a BiW VNF - very minimal testing. I have added the logic to support multiple
port-pairs but have not tested yet. I have included a dump of the flows. The
code is posted to https://github.com/doonhammer/ovs the
