            8       Requirements of the SPSN

            8.1     General requirements

            The general requirements of the SPSN are as follows.
            1)      The SPSN is required to support multiple connections of IoT devices and collaborations with
                    other SPSNs.
            2)      It is recommended that the SPSN support various addressing schemes, e.g., Internet protocol
                    (IP) and non-IP addressing schemes, to interact with the connecting or connected IoT devices.
            3)      The SPSN is required to provide standardized open interfaces for easy capability extensions,
                    e.g., for integration with third party IoT applications and services.

            8.2     Network connectivity
            The  SPSN  provides  logical  connectivity  between  IoT  devices  in  end  user  networks  and
            communication networks.
            The network connectivity requirements of the SPSN are as follows.

            1)      The  SPSN  is  required  to  be  able  to  connect  to  communication  networks  through
                    communication technologies (e.g., 2G/3G/4G/Wi-Fi).

            2)      The SPSN is required to support data exchange between IoT devices and IoT applications
                    and services.

            3)      It is recommended that the SPSN translate data and protocols between IoT devices and IoT
                    applications and services.


            8.3     Local information processing
            The SPSN can support information processing locally. With IoT applications in the SPSN, IoT data
            can be collected, stored, processed and demonstrated in the SPSN directly.
            The local information processing requirements of the SPSN are as follows.
            1)      The SPSN is required to install the IoT applications locally.

            2)      It is recommended that the SPSN store data locally.
            3)      It is recommended that the SPSN compute IoT data locally (e.g., data averaging).
            4)      It is recommended that the SPSN support the user interface (UI) for connected IoT devices.
            5)      It  is  recommended  that  the  SPSN  support  standardized  Web-based  interfaces  [e.g.,
                    representational state transfer- (REST)-ful application programming interfaces (APIs)] with
                    which remote IoT applications and services interact with connected IoT devices.

            8.4     Devices connectivity

            When the SPSN joins an end user network, it can detect the IoT devices in that end user network, and
            the IoT devices can also actively detect and connect to the SPSN.

            The devices connectivity requirements of the SPSN are as follows.
            1)      The SPSN is required to be able to discover and connect to the IoT devices in an end user
                    network, subject to the user's request.
            2)      The SPSN is required to allow access to the connected IoT devices and to allow access from
                    the connected IoT devices, according to pre-defined polices.
            3)      The SPSN is required to connect and disconnect the IoT devices actively, if necessary.
