Hi Brady, Regarding our discussion of Mac Chaining technique and how the original MAC address could be recovery at the end of the chain. We agreed that a L3 router or gateway could do this job. So, I am wondering how could we put this gateway configuration on the SFC model. It’s clear to me that a gateway would NOT be part of the chain itself. So I am think we could create a DPL augmentation to configure the gateway on the topology. Therefore, on the switch that the gateway is connected, we can configure a dpl augmented to be gateway connection, and then set its parameters, such as IP address. In other words, it would be a DPL for the chain termination point.
Is that make sense? Do you have any alternative approaches?? Thanks, Rafael Eichelberger.

I think it would be worthwhile for the 2 of you to consider joining forces to submit a common MAC-based service chaining solution to ODL SFC. I have already replied to Irena when she contacted me in private, and think her Netfloc solution is similar to the ODL Genius project, thus I suggested she also contact the Genius project about adding what may be needed there.

I’m just very curious how you can implement cross-datacenter service function chaining by rewriting MAC.

The objective is to contribute a sfc project to the community. I am involved with SDN topics at the ICCLab in Switzerland and for two years we've been working on SDK for SDN (Netfloc) based on OpenDaylight. Shortly, Netfloc is an archetype of ODL using ovsdb, openflow plugin, neutron-northbound and md-sal. The SFC project is OpenFlow based, uses standard OVS (not NSH enabled and Yang models for the service definition. The implementation is based on abstract mac rewriting pattern and it is bound to Netfloc that uses shortest path algorithm for the virtual network topology. On the management side, it has gui interface and integrates with NFV orchestrator (via ETSI NSD and VNFGD) and OpenStack Heat. The sfc project completed a full cycle of development in the past year and has been validated in PoC cloud-NVI scenario using VNFs as virtual traffic classifier and video transcoding VNF ..now we are deploying multi-dc demo (chaining is only intra-DC). As the sfc is alternative to the odl-sfc project, i would like to know if the best approach is to submit it as a standalone solution, or it rather fits closer to the sfc-odl. I also looked into the opnfv-sfc community that happens to be aligned to the odl, so i am looking to find the best fit for this work.
