Instead of using a physical HW? You need network cables Network cables => NFVI Network Function ization Infrastructure It provides interconnect between the physical cables and the virtual network equipments that are spawned L2 switch, L3 switch, ACL/Switch and network equipments Network Function (equipments) => ized => VNF Network Function (vnf) vipsec, vbras, vrouter, vfirewall, vxxx Openstack provides the framework to spawn Machines Machines can have multiple virtual network interfaces (vmxnet3, virtio) per vm1# ip link show grep virtio wc l Any s with mutiple network interfaces can be any network nodes IPsec, Firewall, Proxy To some extends, the s are the containers of the VNF run vipsec, vfirewall, vproxy Openstack/Neutron and Openstack/Nova VIF drivers provides the automations of the provisioning for interconnecting the s vhost/tuntap, brctl, OVS, L3/routes To some extends, this software interconnect of s is the NFVI v9.3 35
