Rafael,
How would that work in an OpenStack environment? Im thinking of OPNFV
SFC, which is the ideal testing environment for ODL SFC.

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.

Irena/Rafael,
I have looked at both of your ideas, and they seem quite similar. 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.
Regards,
Brady

Thanks for getting back, i will submit a patch as suggested.
You can check out section 5.3 in [1] for the source code
implementation and [2]
for the sfc solution. Also some progress work related to Netfloc
and the sfc in [3].

I was the one from HPE. We are finishing an implementation of MAC
Chaining under ODL, and we are planning to publish a gerrit on
ODL SFC project shortly.
for further details see

I remember a guy from HPE mentioned they implemented service
function chaining by using mac, when ODL SFC can support different
data plane therefore different service function chaining
implementation, Now it can implement service function chaining by
MPLS label, VLAN tag and NSH, so the framework can support new
implementation without any issue, please submit your patch to
Opendaylight gerrit, ODL SFC is very open for anything new J
Do you have any document about your implementation? I’m just very
curious how you can implement cross-datacenter service function
chaining by rewriting MAC.

Hi all,
after contacting few of this community and writing to the irc, i
am writing here.
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.
