Hello Anusha
If I understood you correctly, I don't think that using OpenDaylight
just
for SFC in a network managed by OpenStack its something that has been
attempted before.
A start point would be to let OpenDaylight manage all the networking.
And then add SFC. ODL documentation includes a guide to integrate with
OpenStack [1]. For SFC, the Logical Service Function Forwarder
configuration model should be used [2] and this for the classifier [3].
There might be some additional manual steps required to make SFC working
in Carbon. In Nitrogen, you will get better support for this scenario so
I would go with that if possible.

Hi,
I have been trying to achieve service function chaining with NSH
encapsulation using ODL carbon (distribution-karaf-0.6.1-Carbon).
Openstack
(ocata) allinone node is pre-deployed with the integration of Yi Yang
ovs
nsh patch.
In ODL only SFC features are enabled (odl-sfc-ui,
odl-sfc-openflow-renderer, odl-sfc-scf-openflow, odl-sfc-ovs).
I have created simple topology
Client --- SF1 --- Server
Openstack ALLINONE Node - 192.168.122.9
ODL - 192.168.122.58
client - 10.0.0.4(IP), 23(ofport)
server- 10.0.0.10(IP), 24(ofport)
SF1 - 10.0.0.7(IP), 25(ofport)
When SFC configuration is inserted through REST, I didn't find
classification rules in the ovs node (openstack allinone). The whole
configuration inserted through REST is attached.
Found below error in karaf.log while inserting the Service Function
Classifier configuration through REST and the same was attached.

I have also tried topology which is similar to sfc104 demo. I succeeded
in
achieving SFC with NSH encapsulation using the same ODL distribution
(distribution-karaf-0.6.1-Carbon).
But I could not achieve the same with allinone openstack setup, where
all
the VM's(client, server, SF1) are on single compute node.
Could someone please provide some insights on the same.
Thank you
Best Regards,
Anusha K
