(c) OPNFV, Huawei + ============ Introduction ============ -The OPNFV project provides different kinds of output to its users: - -1. **Target Software Platform** - - This provides the software which will run as NFVI and VIM in an actual NFV deployment - It is an integrated solution of several other open source projects, e.g. OpenStack, - Linux, ODL. - -2. **Deployment Tools** - - So called installers help the user deploy target software on his hardware. - OPNFV provides multiple options to do this. - -3. **Test Cases and Framework** - - The target software platform can be verified and evaluated using these testcases. - Their goal is to show that the deployed platform is usable to run VNFs. - -4. **Documentation** - - OPNFV provides the necessary documents describing target software platform, deployment - tools, tests, etc. in their architecture and usage. - -5. **Requirements** - - OPNFV community works on requirements of open source projects used in OPNFV to - make these projects better suitable for NFV telco carrier use cases. - These requirements are described in requirement documents and also forwarded - to the "upstream" projects in the format required by these projects. - -6. **Community Labs** - - OPNFV creates lab environments not only for development of OPNFV, but also to help - build the NFV ecosystem. OPNFV labs follow a defined structure and configuration. - Some of the labs have their dedicated tasks in the development environment, some of - the labs will be provided for open use. - -**OPNFV Releases** +OPNFV is an integration effort that takes outputs from several open source communities to build a NFV platform. This task of integration leads to providing different kinds of output to its users. + +First of all there is of course the **target software platform**, which is a integrated solution +of a set of components/building blocks of the ETSI ISG NFV reference architecture. +In the Brahmaputra release, this is limited to the NFVI and VIM blocks. +OPNFV users will be able to deploy their VNFs there using some MANO solution. +The target software platform is integrated from a set of other open source components, +of which the biggest ones are OpenStack and SDN controllers. There are multiple combinations +possible and a subset is provided and tested by the Brahmaputra release. These subsets +are called here scenarios. + +Besides the target software platform, OPNFV provides a set of tools that helps the user +deploy this target software platform on a set of servers. These tools are called +**installers**. Brahmaputra provides multiple options here. Naturally the different installers +have different capabilities, that is they support deployment of different **scenarios**. + +The installers allow users to deploy OPNFV target software platform on a bare metal environment +or a set of virtual machines. In both cases, some hosts (bare metal or virtual) will act +as controller nodes, while other hosts will be the compute nodes hosting the VNFs. +The installers use a separate server to control the deployment process. This server is called +"jump server" and is installed with the installer's software at the beginning of a deployment. +The jump server also can be bare metal or virtual. + +This configuration - jump servers and a set of typically 5 nodes to run the target software platform - +is also described as part of an OPNFV release. This allows the users to build their own labs +accordingly and deploy OPNFV easily. A lab compliant to this description sometimes is called +**"Pharos-compliant"** after the OPNFV project providing the lab description. + +Another major part of the OPNFV release is a **testing framework** and test cases. +This test framework allows users to verify their deployment of the OPNFV target software platform. +It will execute and test major functions of the platform relevant to NFV applications (VNFs) so +the user can be confident that VNFs can successfully run. + +Of course, the OPNFV releases come with the necessary **documentation**, describing +target software platform, deployment tools, tests, etc. in their architecture and usage. +The most important documents here are configuration guides and user guides that help to set up +a OPNFV deployment and use it. + +The OPNFV project takes major effort to provide **lab environments** to the community. +The OPNFV community labs of course need to be Pharos-compliant. They are used for OPNFV development +tasks and release creation, but should also provide users with the opportunity to run their own +OPNFV tests. OPNFV community labs are not part of a OPNFV release. + +We should also mention that OPNFV works on **requirements** of open source projects used in OPNFV to +make these projects better suitable for NFV telco carrier use cases. +These requirements are described in requirement documents and also forwarded +to the "upstream" projects in the format required by these projects. +These requirement documents are not bound to OPNFV releases. OPNFV bundles the target software, installers, documentation, test cases and lab -description to releases and provides documentation describing the scope and features +description to **releases** and provides documentation describing the scope and features provided. -Since OPNFV releases contain different options (e.g. for installers, SDN controllers, etc.) -We define a set of scenarios, that is a set of components, combinations -and associated configuration. -This set of scenarios shows which combinations of components and features are tested as -part of the OPNFV release. - This overview document introduces these components and scenarios on a high level and -points you to more -detailed documentation. -It describes the OPNFV Brahmaputra release. +points you to more detailed documentation. -OPNFV Requirement documents typically describe requirements that will be implemented in -later releases of OPNFV. Thus they are not part of a release package. -Also community labs are independent of releases. Only the lab description is included in -the release and describes the requirements of a lab to successfully run Brahmaputra -deployments. |
