The overcloud is OPNFV. Configuration will be passed into undercloud and the undercloud will use OpenStack's orchestration component, named Heat, to execute a deployment that will provision the target OPNFV nodes. + +OPNFV Scenario Architecture +=========================== + +OPNFV distinguishes different types of SDN controllers, deployment options, and +features into "scenarios". These scenarios are universal across all OPNFV +installers, although some may or may not be supported by each installer. + +The standard naming convention for a scenario is: +<VIM platform>-<SDN type>-<feature>-<ha/noha> + +The only supported VIM type is "OS" (OpenStack), while SDN types can be any +supported SDN controller. "feature" includes things like ovs_dpdk, sfc, etc. +"ha" or "noha" determines if the deployment will be highly available. If "ha" +is used at least 3 control nodes are required. + +OPNFV Scenarios in Apex +======================= + +Apex provides pre-built scenario files in /etc/opnfv-apex which a user can +select from to deploy the desired scenario. Simply pass the desired file to +the installer as a (-d) deploy setting. Read further in the Apex documentation +to learn more about invoking the deploy command. Below is quick reference +matrix for OPNFV scenarios supported in Apex. Please refer to the respective +OPNFV Docs documentation for each scenario in order to see a full scenario +description. The following scenarios correspond to a supported <Scenario>.yaml +deploy settings file: + ++-------------------------+------------+-----------------+ +| **Scenario** | **Owner** | **Known Issues**| ++-------------------------+------------+-----------------+ +| os-nosdn-nofeature-ha | Apex | | ++-------------------------+------------+-----------------+ +| os-nosdn-nofeature-noha | Apex | | ++-------------------------+------------+-----------------+ +| os-nosdn-ovs-noha | OVS for NFV| | ++-------------------------+------------+-----------------+ +| os-nosdn-fdio-noha | FDS | | ++-------------------------+------------+-----------------+ +| os-odl_l2-nofeature-ha | Apex | | ++-------------------------+------------+-----------------+ +| os-odl_l3-nofeature-ha | Apex | APEX-112 | ++-------------------------+------------+-----------------+ +| os-odl_l2-sfc-noha | SFC | | ++-------------------------+------------+-----------------+ +| os-odl_l2-bgpvpn-noha | SDNVPN | | ++-------------------------+------------+-----------------+ +| os-odl_l2-fdio-noha | FDS | | ++-------------------------+------------+-----------------+ +| os-onos-nofeature-ha | ONOSFW | | ++-------------------------+------------+-----------------+ +| os-onos-sfc-ha | ONOSFW | | ++-------------------------+------------+-----------------+ |
