Hi All,

I am currently exploring Service Function Chaining (SFC) implementation using OVN and \
would like to hear thoughts from the community.

Has anyone implemented Service Function Chaining using OVN project and would be \
willing to share his/her experiences? There are proposals for adding NSH header as \
well as leveraging MPLS headers (interim solution for lack of NSH support) for SFC \
but can someone more experienced in this topic share if those modifications are \
really necessary for real world SFC use cases? 

With the native support for L2 overlays and ACLs inherently built into OVN, I am \
wondering if we are better off creating point to point overlay networks between the \
VNFs and using ACLs for traffic classification. Or is there more to it than that?

Thanks,

Vikram
