Contiv-VPP is a Kubernetes CNI plugin employing a programmable CNF vSwitch based on open source FD.io/VPP offering feature-rich, high-performance cloud native networking and services.
Kubernetes defines the Container Network Interface (CNI) – an API for network plugins providing connectivity between PODs. That’s worked well so far, but as your cloud native deployments grow and enhanced services are added, new solutions are needed.
First, there is currently no API to map Kubernetes services and policies to network configurations so it’s up to you or the network plugin implementers to figure this out. A standard suite of APIs based on open source code would solve that problem for you.
Second, the use of kube-proxy (with iptables) limits network performance, scale and feature update cycles. required to meet your service and policy demands. Moving all network functions (including data plane and control plane) to user space increases performance, scale, reliability and innovation velocity.
