Spec: Examples library structure and usage

[taylor]

Examples are broken up based on the layers in an environment running a use case

• hardware infra - eg. packet machines
• workload infra - eg. k8s + nsm, k8s + multus, openstack + vpp-networking
• service chains - Combines CNFs to provide a set of services. eg. hardware gateway + firewall + packet filter
• use cases - combine 1 or more service chains with a specific - workload and hardware infra configuration

Examples should be aim to be composable with other examples (especially between layers)

Terminology

• Telecom platform => Telecom hardware infra + Telecom workload infra
• Telecom hardware Infra
  • physical machines, storage devices, routers, switches, etc
• Telecom workload infra
  • k8s, openstack, various services (eg. storage, caching proxy) and overlay network (any supported OSI layer)
• Hardware underlying infrastructure => physical devices, networking (L1 and up)
• NF Use Cases => Sets of Network Service Chains running on a Telecom workload platform with specific configuration for the platform and the Service Chains
• Network Service Chain => Combination of a set of Software Network Functions to provide a higher-level/full service
• Software Network Functions => applications which provide network specific services which can be implemented on a host, vm or as a micro service
