This section describes how to design, develop, and submit a Virtual Network Function for use as a Network Resource in the OpenECOMP environment.

Additionally, this page section includes an outline of actions to be taken by a service provider actions to design and deploy a Service containing a VNF, and to deploy the Service.

The primary audiences for this documentation are

• VNF providers: creators of VNFs (executables and related configuration files)
• Acceptance personnel: thse tasked with certifying VNFs (approving them to run in OpenECOMP environments)

Other audiences who may refer to these documents include:

• Service Designers: those who combine Virtual Functions (including VNFs) into Services in OpenECOMP
• DevOps: those who deploy, operate, and monitor OpenECOMP Services containing VNFs

• general requirements for all VNFsrequirements imposed by the targeted network cloud infrastructure, including the hypervisordesign requirements (API versioning, decomposition, reliance on open source database, packet size limitations)
• resiliency requirements
• security requirements

<<DocRef: VNF Management Requirements for OpenECOMP>>

• requirements imposed by the targeted network cloud infrastructure, including the hypervisor
• identification requirements for the design requirements: identification of VNF and its components
• configuration management requirements
  
  • a VNF must provide a Device YANG model
  • a VNF must implement a NETCONF server; the required NETCONF API's are referenced, and the supplier must demonstrate mounting the NETCONF server on OpenDaylight
• monitoring and operations requirements
  • format of messages (event records)
  • frequency of reporting
  • security
• licensing requirements
