For this, any virtual +switch should make use of +hardware accelerators and optimized cache operation to be run in user space. + +The apex-os-odl_l3-ovs-noha scenario provides +use-cases for deployment of NFV nodes instantiated by +an Openstack orchestration system on OVS/DPDK enabled compute nodes +with Open Daylight controller service. + +A deployment of the "apex-os-odl_l3-ovs-noha" scenario consists of 3 or more +servers: + + * 1 Jumphost hosting the APEX installer - running the Undercloud + * 1 Controlhost, which runs the Overcloud, Openstack services and + Open Daylight service + * 1 or more Computehosts or nodes + +.. image:: ovs4nfv.png + +Tenant networking leverages Open vSwitch accelerated with a fast user space data path such +as DPDK. +Open VSwitch (OVS) with the Linux kernel module data path is used for all other +connectivity, such as connectivity to public networking "the +Internet" (i.e. br-ex) is performed via non-accelerated OVS. + +Features of the scenario +------------------------ + +Main features of the "apex-os-ovs-nosdn-noha" scenario: + + * Automated installation using the APEX installer + * Accelerated tenant networking using OVS/DPDK as the forwarder + * VXLAN l3 tenant network support with accelerated DPDK ports. + +Networking in this scenario using OVS with accelerated User space IO. +--------------------------------------------------------------------- + +The apex-os-odl_l3-ovs-noha scenario combines components from three open +source projects: OpenStack, Open vSwitch and DPDK.
