CNF (Cloud native Network Function) Testbed
The CNCF CNF Testbed provides reference code and test cases for running networking code on Kubernetes and OpenStack using emerging cloud native technologies in the Telecom domain.
Status: The CNF Testbed is an initiative to create a repeatable, apples-to-apples testbed that telcos and telecoms vendors can use to evaluate how CNF architectures compare to more traditional VNF ones.
The initiative collaborates with the CNCF Telecom User Group to test and demonstrate different options.
Note: Additional reference code and benchmarking tests will be added incrementally.
CNF Testbed purpose and ideal outcome?
The CNF Testbed will help facilitate the transition in the NFV world from virtualized hardware running network functions to lightweight, network functions following cloud-native methodologies running on Kubernetes in public, private, or hybrid clouds.
The reference code and comparisons from the CNF Testbed support the claim that CNFs orchestrated by Kubernetes will provide 3 major benefits to service providers:
- Cost savings (capex/opex)
- Improved resiliency
- Higher development velocity
The ideal outcome of the CNF Testbed is that a third party developer can run the provided CNF reference code/benchmarking tests with an API key and a couple of CLI commands. Furthermore, a developer can re-use some or all of the software in their own environment with minimal, or at least isolated modifications.
Please review this slide deck.
CNF Testbed goals
The CNF Testbed includes the following high-level goals:
- Development platform for CNFs
- Comparing Virtual Network Functions (VNFs) to CNF implementations
- Providing easily reproducible test cases and use cases
- Providing Helm Charts for CNFs
- Using 100% open source software
- Supporting automated deployment from bare-metal up
- Building the software in working, composable parts
Let’s see some of the test cases
So far the project has been focused on provisioning the infrastructure to support data plane CNF test cases that would be of interest to a service provider. This includes building up from minimal, single NFs running on KVM and Docker to OpenStack and K8s.
Events and recurring testing:
- (recurring) Baseline NF Performance on Packet
- (recurring) Baseline NF Performance on CSIT
- Mellanox Chained IP Routers: OpenStack & K8s
- Kubecon NA 2019 Chained IP Routers
- Box-by-box KVM and Docker
Getting Involved and Contributing
Are you interested in contributing to CNFs? We, the maintainers and community, would love your suggestions, contributions, and help! Please email email@example.com or open an issue or pull request if you have questions or suggestions.
What this means:
- Point out issues that are duplicates, out of date, etc.
- Read and review the code. Leave comments, questions, and critiques.
- Download, compile, and run the code and make sure the tests pass.
- Also verify that the test cases follow best architectural patterns and include tests.
The CNF Testbed is discussed as part of the CNCF Telecom User Group. Please see https://github.com/cncf/telecom-user-group#meeting-time.
