Background
...
In R2, SO is the only consumer of OOF. When it sends out homing requests, OOF will respond with the most appropriate flavors accordingly.
...
Now in R3, OOF is going to support both two orchestrators (SO and VF-C) in ONAP. As they are using two different Models(HEAT and Pure Tosca), the expression differs from each other. In order to make OOF capable to process these two different requests within the same engine, we'd like to combine these expressions together inside a single Policy.
Sample Policy Schema
Thus a data block called 'directives' and some attributes(type and vduName) will be added inside policy to transfer the information that needed by OOF. And it also contains two parts, one includes the flavor at a VNFC level, the other contains the specific information needed by such hpa-feature.
