Miguel OpenStack networking-sfc does support SFs with separate ingress and egress Neutron ports. A port-pair consists of an ingress Neutron port and an egress Neutron port. Multiple port-pairs (SFs) with similar functionality may be included in a port-pair-group which is one stage in a SFC (port-chain). Each port-pair group provides LB functionality across the SFs in the PPG. Multiple PPGs make up a port-chain. Networking-sfc supports different back-end implementations including OVS, ONOS, ODL.

Is it possible to have a SF with two interfaces (egress/ingress) and have the traffic in the chain being sent through one of them and received through the other? +---------+ +---------+ | Current | | Desired | | | => | | | | | | +---------+ +---------+ | | | | | | + + + XXX XXXXXXX XX XX XX XX SC XXXXX XXXXX XXXX XXXX The purpose of this is to allow a firewall to be placed as Service Function. In this type of devices we need the traffic flowing from one interface to a different one. I know this was not possible some months ago, but maybe this feature has been already added recently? I'm also curious to know why this is different to OpenStack + NetworkingSFC + ODL: In this deployment openstack allows the SF to have an ingress and egress port which can be placed on different interfaces/data plane locator.
