Cloud Infrastructure for Distributed Clouds (5G etc.) – Networking Focused (only the unique aspects from the previous section are brought out)

ONAP Component	Life Cycle Phase	Enhancements
Policy	Design	Define Distributed Cloud Infrastructure Network

Realization Policies

Intent Per Cloud Region (Note 1)

Leverage Standardized Distributed Cloud Infrastructure Object Hierarchy & Capabilities from A&AI

Multi-Cloud (MC)

Deploy

MC <-> SDN-DC (Private Cloud) or MC <-> Public Cloud interaction

Translate Cloud Agnostic intent to Cloud specific intent or imperative APIs by querying Policy
Return network endpoint (used for VNF placement)

SO

Deploy

Option 1: (SO -> MC -> Private/Public SDN-DC) -- desired

SO <-> MC IaaS Intent-based API (BesidesOne or more of Compute/Network/Storage/Analytics)

Option 2: (SO -> SDN-C -> MC → Private/Public SDN-DC)

SO <-> SDN-C interaction
- SO uses the Generic Resource API (SDN-C NB) to SDN-C to determine the right Directed Graph to invoke
- The Generic Resource API can be used to pass the cloud region and other cloud agnostic intent
SDN-C <-> MC IaaS Intent-based API
- By looking up the directed graph, SDN-C calls MC with a programmable intent-based API which includes cloud region and other cloud agnostic intent

Note 1:

Cloud Agnostic Intent-based API example 1
- Intent: High Performance intra-DC data plane networking with no Host CPU usage
