OpenStack is a free, ... Neutron is an OpenStack project to provide "network connectivity as a service" between interface devices (e.g., vNICs) managed by other ...
It is mostly deployed with OpenStack Neutron but it assumes that many features and software-defined networking (SDN) capabilities of Openstack are disabled. For instance, when OVS-DPDK is used, Neutron provides a lower level of security than when OVS kernel is used (no stateful firewalling, less security group).
In case of SDN controllers for the NFV Infrastructure of a datacenter, they are mostly designed to provide some policy and centralized managements for the Openstack Neutron networking layer that will provide inter-working between the virtual ports created by Nova.

Neutron, the networking component of the open-source software OpenStack project, provides an application-level abstraction of network resources and includes an interface for configuring virtual switches. [11] [17] The software-defined data center approach will force IT organizations to adapt.
OVN is the software-defined networking (SDN) platform used in a number of Red Hat products, including Red Hat Virtualization, [5] OpenStack, [6] and OpenShift. [ 7 ] OVN is written in platform-independent C language , which provides easy portability to various environments.
oVirt can be integrated with many open source projects, including OpenStack Glance and Neutron for disk and network provisioning, Foreman/Katello for VM/node provisioning or pulling relevant errata information into webadmin portal and can be further integrated with ManageIQ for a complete virtual infrastructure lifecycle management. [7]
For example, in case of Openstack, network is provided by Neutron which leverages many features from the Linux kernel for networking: iptables, iproute2, L2 bridge, L3 routing or OVS. Since the Linux kernel cannot sustain the 10G packet rate [ citation needed ] , then some bypass technologies for a fast path are used.
