- Summary
This input includes following proposals- Simplified NsVirtualLink Toscal Model.
- Simplified Network Service Virtual Link model.
Below is the simplified model for the TOSCA which proposes to merge the properties in virtual link descriptor, virtual link deployment flavour and virtual link profiles in to one node type NsVirtualLink.
Following are modeled as Data Types
