VDU proposal comparison

VDU proposals Option 1:Mapping between NFV model and TOSCA-v3.ppt (Huawei,IBM, Brocade) Option 2:Issue_TOSCA310_VDU change proposal v2.zip (NOKIA) Option 1 Option 2

Main different VDU topology Descriptor sharing SwImageDesc virtualStorageDesc virtualComputeDesc Option 1 TOSCA composition mechainism TOSCA DSL_definition mechanism TOSCA artifact mechainism Derived from TOSCA storage node, different types of virtual storage shall have different node types. New tosca.capabilities.nfv.Compute.Container Derived from tosca.capabilities.compute Align with IFA UML definition Align with TOSCA Align with IFA requirements Not align with IFA model, but fulfill their requirement May need to change IFA model, but fulfill their requirements Align with TOSCA mechanism. Option 2 Relationship link based Requirement link New node type, New relationship type needed New node type Existing TOSCA relationship type can not be used to describe the connection in IFA UML model Not align with TOSCA Not align with IFA model (One of the side effect is that it indicates not only descriptor sharing but also instance sharing) Align with IFA model
