Service Function Chain (SFC) Management¶
Prerequisites¶
The following packages should be installed:
tacker
python-tackerclient
A default VIM should be registered according to VIM Management.
The following VNFDs are created with the name VNFD1 and VNFD2
according to VNF Descriptor (VNFD) Management.
$ openstack vnf descriptor create --vnfd-file tosca-vnffg-vnfd1.yaml VNFD1
$ openstack vnf descriptor create --vnfd-file tosca-vnffg-vnfd2.yaml VNFD2
The VNFs from the created VNFDs are deployed with the name VNF1 and
VNF2 according to VNF Management.
$ openstack vnf create --vnfd-name VNFD1 VNF1
$ openstack vnf create --vnfd-name VNFD2 VNF2
A VNFFG should be deployed according to VNF Forwarding Graph (VNFFG) Management. Before deploying the VNFFG, a VNFFGD may need to be created according to VNF Forwarding Graph Descriptor (VNFFGD) Management.
