The main components of the "apex-os-nosdn-ovs-ha" scenario +are: + + - APEX (TripleO) installer (please also see APEX installer documentation) + - Openstack (in HA configuration) + - OVS/DPDK Open vSwitch with DPDK data plane virtual forwarder for tenant networking + +Introduction +============ + +NFV and virtualized high performance applications, such as video processing, +require Open vSwitch to be accelerated with a fast data plane solution that provides both +carrier grade forwarding performance, scalability and open extensibility. + +A key component of any NFV solution is the virtual forwarder, which should consist of +soft switch that includes an accelerated data plane component. For this, any virtual +switch should make use of +hardware accelerators and optimized cache operation to be run in user space. + +The "Openstack - Open vSwitch/DPDK" scenario provides +use-cases for deployment of NFV nodes instantiated by +an Openstack orchestration system on OVS/DPDK enabled compute nodes. + +A deployment of the "apex-os-nosdn-ovs-ha" scenario consists of 3 or more +servers: + + * 1 Jumphost hosting the APEX installer - running the Undercloud + * 1 Controlhost, which runs the Overcloud and Openstack services + * 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-ha" scenario: + + * Automated installation using the APEX installer + * Accelerated tenant networking using OVS/DPDK as the forwarder + +Networking in this scenario using OVS with accelerated User space IO. +--------------------------------------------------------------------- + +The apex-os-nosdn-ovs-ha scenario combines components from three open +source projects: OpenStack, Open vSwitch and DPDK.
