EXAMPLE-CNFs (DRAFT)

This is a preliminary list of CNF samples for each layer in the OSI model which we plan to test in the CNF Conformance Test Suite

Goals:

• Find a CNF which can be used as a sample in the CNF Conformance suite for testing on each layer in the osi-model.
  • Ideally it will be a different CNF for each layer, but this is not a hard requirement.
• Provide a summary of the CNFs for each layer
• Provide a description of what each CNF is and what it does for each layer.

Layer 7 - Application

• CoreDNS Sample CNF
• NFF Go Deep Packet Inspection example example

Layer 6 - Presentation

• NFF Go Deep Packet Inspection example example

Layer 5 - Session

• Netify
  • uses Rsocket, a layer 5/6 binary protocol

Layer 4 - Transport

• NFF Go Anti DDOS example
• NFF Go NAT example
• Envoy (L3+L4)
• Istio
• linkerd2
  • Also Application Layer
  • Linkerd proxy-Automatic layer-4 load balancing for non-HTTP traffic- Tungsten Fabric

Layer 3 - Network

• NFF Go IP Forwarding example
• NFF Go IPsec example
• CNF Testbed IPsec example
• NFF Go NAT example
• Envoy (L3+L4)
• Flannel configures a layer 3 IPv4 overlay network
• FRRouting (github repo)
• Tungsten Fabric
• OpenSwitch NAS Layer 3
• CNI K8s add-ons operating on Layer 3 such as the Calico kube-policy-controller container

Layer 2 - Data

• VPP-based IP Forwarder - See CNF Testbed 3c2n-csp example use case
• VPP-based Bridge or vSwitch
• Linux vNics
• NFF Go NAT example
  • MAC address for "internal" machine
• PDN GW
• Serving GW
• OvS
• Something from O-RAN (wiki, repos)
• OMEC component
• FRRouting (github repo)
• Tungsten Fabric
• OpenSwitch NAS Layer 2
• Packet pROcessing eXecution (PROX) engine automated with Rapid scripts for use cases like NFVI performance characterization (Readme, Test case) or CNF Resilience testing (Engine config)
