Hi Juno,
Each flow-classifier has a mandatory logical-source port (mandatory for OVS driver).If it is mandatory for OVN driver also, you should be able to get the lswitch fromthe logical source port in the flow classifier.

John,

Here is the steps to configure sfc,
1, create flow-classifer
2, create port-pairs
3, create port-pair-group with port-pairs
4, create port-chain with flow-classifer and port-pair-groups

You can see that the port-chain is not related to network, my question is 
how to get the lswitch for networking-sfc and write it to database?

Juno,

It is a container for port-pair-groups and flow-classifier. I imagine 
there could be more the than one port-chain per switch. Also we may want 
to extend the model beyond a single lswitch

Hi John,

Another question, I think port-chain is irrelevant with lswitch, one 
port-chain includes multiple port-pair-groups and one flow-classifier, how 
to get the lswitch by port-chain?

The reason I did that was to be able to create reusable VNF's
