    virtualized resources (nodes) requirements as well as connectivity
    and interfaces requirements and **MUST** comply with info elements
    specified in ETSI GS NFV-IFA 011. The main parts of the VNFD are
    the following:

      - VNF topology: it is modeled in a cloud agnostic way using virtualized
        containers and their connectivity. Virtual Deployment Units (VDU)
        describe the capabilities of the virtualized containers, such as
        virtual CPU, RAM, disks; their connectivity is modeled with VDU
        Connection Point Descriptors (VduCpd), Virtual Link Descriptors
        (VnfVld) and VNF External Connection Point Descriptors
        (VnfExternalCpd);

      - VNF deployment aspects: they are described in one or more
        deployment flavours, including configurable parameters, instantiation
        levels, placement constraints (affinity / antiaffinity), minimum and
        maximum VDU instance numbers. Horizontal scaling is modeled with
        scaling aspects and the respective scaling levels in the deployment
        flavours;

    **Note**: The deployment aspects (deployment flavour etc.) are postponed
    for future ONAP releases.

      - VNF lifecycle management (LCM) operations: describes the LCM operations
        supported per deployment flavour, and their input parameters;
        Note, thatthe actual LCM implementation resides in a different layer,
        namely referring to additional template artifacts.

PNF Plug and Play > PNF Plug and Play
-------------------------------------


Requirements Added
~~~~~~~~~~~~~~~~~~
    

.. container:: note

    :need:`R-01427`

    The PNF **MUST** support the provisioning of security and authentication
    parameters (HTTP username and password) in order to be able to authenticate
    with DCAE (in ONAP).

    Note: In R3, a username and password are used with the DCAE VES Event
    Listener which are used for HTTP Basic Authentication.

    Note: The configuration management and provisioning software are specific
    to a vendor architecture.
    

.. container:: note

    :need:`R-106240`

    The following VES Events **MUST** be supported by the PNF: pnfRegistration
    VES Event, HVol VES Event, and Fault VES Event. These are onboarded via
    he SDC Design Studio.

    Note: these VES Events are emitted from the PNF to support PNF Plug and
    Play, High Volume Measurements, and Fault events respectively.
    

.. container:: note

    :need:`R-17624`

    The PNF **MAY** support the optional parameters for Service
    Configuration Parameters.

    Note: These are detailed in the Stage 5 PnP

    Note: These parameters are optional, and not all PNFs will support any
    or all of these parameters, it is up to the vendor and service provider
    to ascertain which ones are supported up to an including all of the ones
    that have been defined. Note: It is expected that there will be a growing
    list of supported configuration parameters in future releases of ONAP.
    

.. container:: note

    :need:`R-256347`

    The PNF **MUST** support the Ansible protocol for a Service Configuration
    message exchange between the PNF and PNF Controller (in ONAP).

    Note: this exchange may be either Ansible, Chef, or NetConf depending on
    the PNF. Note: The PNF Controller may be VF-C, APP-C or SDN-C based on the
    PNF and PNF domain. Note: for R3 (Casablanca) only Ansible is supported.
    

.. container:: note

    :need:`R-258352`

    The PNF **MUST** support & accept the provisioning of an ONAP contact IP
    address (in IPv4 or IPv6 format).

    Note: For example, it a possibility is that an external EMS would configure
    & provision the ONAP contact IP address to the PNF (in either IPv4 or
    IPv6 format). For the PNF Plug and Play Use Case, this IP address is the
    service provider's "point of entry" to the DCAE VES Listener.

    Note: different service provider's network architecture may also require
    special setup to allow an external PNF to contact the ONAP installation.
    For example, in the AT&T network, a maintenance tunnel is used to access
    ONAP.
    

.. container:: note

    :need:`R-284934`

    If the PNF encounters an error authenticating, reaching the ONAP DCAE VES
    Event listener or recieves an error response from sending the pnfRegistration
    VES Event, it **MAY** log the error, and notify the operator.

    Note: the design of how errors are logged, retrieved and reported
    will be a vendor-specific architecture. Reporting faults and errors
    is also a vendor specific design. It is expected that the PNF shall
    have a means to log an error and notify a user when a fault condition
    occurs in trying to contact ONAP, authenticate or send a pnfRegistration
    event.
    

.. container:: note

    :need:`R-378131`

    (Error Case) - If an error is encountered by the PNF during a
    Service Configuration exchange with ONAP, the PNF **MAY** log the
    error and notify an operator.
    

.. container:: note

    :need:`R-56718`

    The PNF Vendor **MAY** provide software version(s) to be supported by PNF
    for SDC Design Studio PNF Model. This is set in the PNF Model property
    software_versions.
    

.. container:: note

    :need:`R-579051`

    The PNF **MAY** support a HTTP connection to the DCAE VES Event Listener.

    Note: HTTP is allowed but not recommended.
    

.. container:: note

    :need:`R-638216`

    (Error Case) - The PNF **MUST** support a configurable timer to stop the
    periodicity sending of the pnfRegistration VES event. If this timer expires
    during a Service Configuration exchange between the PNF and ONAP, it
    MAY log a time-out error and notify an operator.

    Note: It is expected that each vendor will enforce and define a PNF
    service configuration timeout period. This is because the PNF cannot
    wait indefinitely as there may also be a technician on-site trying to
    complete installation & commissioning. The management of the VES event
    exchange is also a requirement on the PNF to be developed by the PNF
    vendor.
    

.. container:: note

    :need:`R-686466`

    The PNF **MUST** support sending a pnfRegistration VES event.

    The PNF **MUST** support a HTTPS connection to the DCAE VES Event
    Listener.
    

.. container:: note

    :need:`R-793716`

    The PNF **MUST** have "ONAP Aware" software which is capable of performing
    PNF PnP registration with ONAP. The "ONAP Aware" software is capable of
    performing the PNF PnP Registration with ONAP MUST either be loaded
    separately or integrated into the PNF software upon physical delivery
    and installation of the PNF.

    Note: It is up to the specific vendor to design the software management
    functions.
    

.. container:: note

    :need:`R-809261`

    The PNF **MUST** use a IP address to contact ONAP.

    Note: it is expected that an ONAP operator can ascertain the ONAP IP
    address or the security gateway to reach ONAP on the VID or ONAP portal
    GUI.

    Note: The ONAP contact IP address has been previously configured and
    provisioned prior to this step.

    Note: The ONAP IP address could be provisioned or resolved through
    FQDN & DNS.
    

.. container:: note

    :need:`R-894004`

    When the PNF sets up a HTTP or HTTPS connection, it **MUST** provide a
    username and password to the DCAE VES Collector for HTTP Basic
    Authentication.

    Note: HTTP Basic Authentication has 4 steps: Request, Authenticate,
    Authorization with Username/Password Credentials, and Authentication Status
    as per RFC7617 and RFC 2617.
    

.. container:: note

    :need:`R-952314`

    If the PNF set up a TLS connection and mutual (two-way) authentication is
    being used, then the PNF **MUST** provide its own X.509v3 Certificate to
    the DCAE VES Collector for authentication.

    Note: This allows TLS authentication by DCAE VES Collector.

    Note: The PNF got its X.509 certificate through Enrollment with an
    operator certificate authority or a X.509 vendor certificate from the
    vendor factory CA.

    Note: In R3 three authentication options are supported:

    (1) HTTP with Username & Password and no TLS.

    (2) HTTP with Username & Password & TLS with two-way certificate
        authentication.

    (3) HTTP with Username & Password & TLS with server-side
        certificate authentication.
    

.. container:: note

    :need:`R-980039`

    The PNF **MUST** send the pnfRegistration VES event periodically.
    

.. container:: note

    :need:`R-981585`

    The pnfRegistration VES event periodicity **MUST** be configurable.

    Note: The PNF uses the service configuration request as a semaphore to
    stop sending the pnfRegistration sent. See the requirement PNP-5360
    requirement.
