On the ACL preceding or integrated with the sfc flow - I think ACL has to be applied first then the classifier channels the packets to the respective network that has VNFs. The scope of sfc flow programming is generally orthogonal to how the network is setup and where classifier is placed, which

In the old poc (march - may 2015) the way the service chains worked was a custom flow programmed based on an nsh key per chain. The nsh header was sort of the service chain key. The flow was programmed from ovs agent. For instance you would have video compression and url filter on a chain. They

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
