Hi all, First, I am not involved in tacker or in networking-sfc, so I can be wrong. Just to be sure by 'multiple VIM' you mean multi domains, multi autonomous systems, multi OpenStack/VNFinfra sites that are all different? When it comes to VNFFG over multiple VIM, I think a question is: what does the networking-sfc driver already support? Some other questions: 1. In a single VIM situation, does the networking-sfc driver support VNFFG (or port chaining) over multiple different IP subnets? 2. Does networking-sfc support both IPv4 and IPv6? 3. What routing/steering protocol (NSH, SRv6) does networking-sfc support? 4. How healthy (or up to date) is the development of networking-sfc? I think modifying tacker (or modifying any other VNF Orchestrator that is plugged to an OpenStack VIM with networking-sfc driver installed) alone is not enough. Maybe VNFFG over multiple VIM needs an SDN controller, maybe it needs new feature in the networking-sfc driver or new features in neutron... --- Nicolas On 2019-01-11 12:31, Dharmendra Kushwaha wrote:

Dear Lee,

Good point & Thanks for the proposal.

Currently no ongoing activity on that. And That will be great help if you lead this feature enhancement.

Feel free to join Tacker weekly meeting with some initial drafts.

Thanks & Regards

Dear Tacker folks,

Hello, I'm interested in implementing multisite VNFFG in Tacker project.

As far as I know, current single Tacker controller can manage multiple Openstack sites (Multisite VIM), but it can create VNFFG in only singlesite, so it can't create VNFFG across multisite. I think if multisite VNFFG is possible, tacker can have more flexibility in managing VNF and VNFFG.

In the current tacker, networking-sfc driver is used to support VNFFG, and networking-sfc uses port chaining to construct service chain. So, I think extending current port chaining in singleiste to multisite can be one solution.

Is there development process about multisite VNFFG in tacker project? Otherwise, I wonder that tacker is interested in this feature. I want to develop this feature for Tacker project if I can.

Yours sincerely,

Hochan Lee.
