[Linda] Are those "Mapping" being provided by providers before the Applications need to use them? In another words, are those mappings statically configured ahead of time? So that Applications can search through the available ones and map themselves?

Linda

If there is a mechanism and a set of models (e.g. Yang models) of the demands for the application to use the network capabilities instantly, the application can use the network capabilities easily and the deployment of new application/service will be accelerated.

[Linda] I would think that Yang Models would be the second step. The first step might be having a signaling model for applications to search through the available mappings and choose the one that fit them the best. Then they can use Yang Model to send their desired mapping to the network.

To let application easily use network capabilities and to let the acceleration of new application/service deployment, "mapping application's demands on network to the policy understood by network" and "a set of models (e.g. Yang models) for different types demands on network", may needed in IETF. So, after authorization, the application can use related network capabilities within the allowable range in an open way. This is useful for new application innovation and the openness of network capabilities to application.
