Converge on common configuration terminology

[johnbelamaric]

"Configuration" is a very generic word. We need to come up with some common language. Here is an initial proposal to get the discussion started:

• Network Topology: Placement of network functions across the geographically distributed fleet of clusters, and associated configuration variations. Example resources: FiveGCoreTopology, PackageDeployment, PackageVariantSet
• Network Configuration: Configuration representing the runtime behavior of network functions, along with a model for capturing vendor-specific differentiating configuration of those functions. Example resources: UPFDeployment
• Network Function Workload: Configuration representing provisioning-time definitions of standards-driven network functions, along with a model for capturing vendor-specific differentiating configuration associated with those functions. Example resources: UPFClass, UPF, NFInstanceSet
• Workload Primitives: Standard Kubernetes resources such as Deployments, along with extensions that provide node and node interface level configuration, such as SR-IOV and Multus.
• Workload Fabric: Configuration of networking infrastructure driven on a per-workload basis, rather than as part of the platform-level infrastructure. For example, configuration VLAN/VRF-lite in top-of-rack and spine switches.
• MEC / Cloud Infrastructure: Configurations for defining virtualized, API-driven on-demand consumption of the physical layer. Includes abstract resources such as Kubernetes clusters. Example resources: Upstream cluster resources, maybe some BIOS resources?
• Physical Infrastructure: Physical compute, networking, and storage devices and their associated configurations (out-of-scope).

Network Topology -> I would say network is an overloaded term. if you would say this to network people they have a total different perspective on this. I would call this NF Topology.

Network Configuration -> I would call this NF Configuration

Network Function Workload -> I would call this NF Deployment

Workload I would call server network config (CNI/Multus) and fabric is network fabric (it can be physical or virtual)

I think we should still work on this going into R2, we're getting closer but need more common language.
