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.
