SDC Sprint 24
The transformation of PNF Descriptor from the onboarded package to a ONAP VSP package is currently coded in Java. For every new transformation the code must be changed.
Having a model-driven approach to the transformation would avoid any code change, just a change on the described transformation model.
Currently those are the operations applied to the PNFD yaml descriptor file:
- Change of an attribute name
#from
topology_template:
node_templates:
pnfExtCp_1:
properties:
layer_protocols: [...]
#to
topology_template:
node_templates:
pnfExtCp_1:
properties:
ip_requirements: [...] # attribute name changed
- Change of an attribute value
#from
topology_template:
node_templates:
pnfExtCp_1:
type: tosca.nodes.nfv.PnfExtCp
#to
topology_template:
node_templates:
pnfExtCp_1:
type: org.openecomp.resource.cp.v2.extCP #value replaced
- Conversion of selected values inside a list attribute
#from
topology_template:
node_templates:
pnfExtCp_1:
properties:
layer_protocols:
- ipv4
- ipv6
- otherProtocol
- yetAnotherProtocol
#to
topology_template:
node_templates:
pnfExtCp_1:
properties:
ip_requirements: #name changed and selected values replaced in list
- assingment_method: dhcp
ip_version: 4
- assingment_method: dhcp
ip_version: 6
- Conversion of an input called by get_input TOSCA function, which combines the previous conversions and adds attribute copying.
