There is tremendous interest in deploying NFV workloads from Kubernetes in Edges as Edges can't afford to have two resource orchestrators - One for applications and another for VNFs/CNFs. NFV workloads can be management plane workloads, control plane workloads and user plane/data plane workloads. Data plane workloads normally have multiple interfaces, multiple subnets, and multiple virtual networks. Some data plane workloads require SR-IOV NIC support for data interfaces and virtual NIC for other interfaces. NFV workloads may require dynamic creation of virtual networks and dynamic configuration of subnets. Some NFV's also require provider network support. There is also a requirement for route management across virtual networks and external networks.

Ovn-kubernetes project (https://github.com/ovn-org/ovn-kubern...) is Kubernetes integration for OVN. To meet NFV requirements as listed above some functionality beyond the functionality provided by ovn-kubernetes is required. To fill the functionality gaps a project under OPNFV is started called ovn4nfvk8s Plugin (https://github.com/opnfv/ovn4nfv-k8s-.... This project is filling in the functionality gap by providing dynamic creation and deletion for virtual networks and provider networks, adding multiple interfaces to workloads either virtual network interface or provider network interface and route management for these networks. This project works with Multus to provide a CNI to attach multiple OVN interfaces into workloads and supports CRD controllers for dynamic networks and provider networks and for route management.
