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.
