Classes from Common Sub-Model

AffinityOrAntiAffinityGroup 

The AffinityOrAntiAffinityGroup class describes the affinity or anti-affinity relationship. For NSs, those rules are applicable between the VNF instances created using different VnfProfiles, the Virtual Link instances created using different VlProfiles or the nested NS instances created using different NsProfiles.

 

For VNFs, those rules are applicable between the virtualization containers to be created based on different VDUs, or between internal VLs to be created based on different VnfVirtualLinkDesc(s).
