-Scenario: "OpenStack - ovs-nfv"
-=============================
-
-Scenario: apex-os-nosdn-ovs-noha
-
-"apex-os-ovs-noha" is a scenario developed as part of the OVS for NFV
-OPNFV project. The main components of the "apex-os-nosdn-ovs-noha" scenario
-are:
-
- - APEX (TripleO) installer (please also see APEX installer documentation)
- - Openstack (in non-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-noha" 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
-

-
-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-ext) 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
-
-Networking in this scenario using OVS with accelerated User space IO.
----------------------------------------------------------------------
-
-The apex-os-nosdn-ovs-noha scenario combines components from three open
-source projects: OpenStack, Open vSwitch and DPDK. To make accelerated networking
-available for this scenario Open vSwitch is bound via its netdev interface
-with DPDK user space accelerated capability.
-
-Scenario Configuration
-======================
-
-To enable the "apex-os-nosdn-ovs-noha" scenario check the appropriate settings
-in the APEX configuration files. Those are typically found in /etc/opnfv-apex.
-
-File "deploy_settings.yaml" choose false for sdn controller::
-
- global_params:
- ha_enabled: false
-
- deploy_options:
- sdn_controller: false
- sdn_l3: false
- tacker: false
- congress: false
- sfc: false
- vpn: false
-
-Validated deployment environments
-=================================
-
-The "os-odl_l2-ovs-noha" scenario has been deployed and tested
-on the following sets of hardware:
- * TBD
-
-
-Limitations, Issues and Workarounds
-===================================
-
-There are no known issues.
