VMware Telco Cloud Automation uses modified TOSCA, which is an extension of the standard TOSCA, to determine prerequisites for different VIMs.
The root node tosca.nodes.nfv.VMware.VNF defines the VNF definition like CaaS and NodeConfig related requirements in the TOSCA.
The infra_requirements property at the root node defines these infrastructure requirements for the Network Function.
The sample shows customized TOSCA with the infrastructure requirements definition.
