    Application profiles allows application developers to share all the
    information about their application which would be relevant for network/
    CAMARA APIs related decision making.

    To start with the API will provide operations to define, read and manage
    an application's thresholds for network quality (latency, jitter, loss,
    throughput). This scope will be expanded further based on addtional
    requirements from other applicable CAMARA APIs

    ### Authorization and authentication

    The "Camara Security and Interoperability Profile" provides details on how a client requests an access token. Please refer to Identify and Consent Management (https://github.com/camaraproject/IdentityAndConsentManagement/) for the released version of the Profile.

    Which specific authorization flows are to be used will be determined during onboarding process, happening between the API Client and the Telco Operator exposing the API, taking into account the declared purpose for accessing the API, while also being subject to the prevailing legal framework dictated by local legislation.

    It is important to remark that in cases where personal user data is processed by the API, and users can exercise their rights through mechanisms such as opt-in and/or opt-out, the use of 3-legged access tokens becomes mandatory. This measure ensures that the API remains in strict compliance with user privacy preferences and regulatory obligations, upholding the principles of transparency and user-centric data control.

        The packet delay budget is the maximum allowable one-way latency
        between the customer's device and the gateway from the operator's
        network to other networks. By limiting the delay, the network
        can provide an acceptable level of performance for various services,
        such as voice calls, video streaming, and data. The end-to-end or
        round trip latency will be about two times this value plus the latency
        not controlled by the operator

      description: |
        The exponential power of the allowable error loss rate 10^(-N).
        For instance 3 would be an error loss rate of 10 to the power of -3
        (0.001)

        For 5G network the 3GPP specification TS 23.203 defines the packet
        error loss rate QCI attribute. It describes the Quality of Service
        (QoS) Class Identifier (QCI) parameters used to differentiate traffic
        classes in mobile networks, ensuring appropriate resource
        allocation and performance for various services.

        The packet error loss rate is one of the QCI attributes, providing
        information on the acceptable packet loss rate for a specific traffic
        class. This attribute helps maintain the desired performance level for
        services like voice calls, video streaming, or data transfers within
        the 3GPP mobile network.

    jitter:
      description: |
        The jitter requirement aims to limit the maximum variation in
        round-trip packet delay for the 99th percentile of traffic, following
        ITU Y.1540 standards. It considers only acknowledged packets in a
        session, which are packets that receive a confirmation of receipt from
        the recipient (e.g., using TCP). This requirement helps maintain
        consistent latency, essential for real-time applications such as VoIP,
        video calls, and gaming.
