Unleashing the potential of the Internet of Things 3

– Addressing
The gateway is required to support various addressing schemes, e.g., IP and non-IP
addressing schemes, including public and private addressing for IP schemes.
– Openness to functional extensions
The gateway is required to provide standard interfaces to support functional extensions of
the gateway, e.g., for deployment in diversified application environments.
– Quality of service
The gateway usually plays a key role in the IoT application scenarios where quality of
service (QoS) support is essential.
The QoS related requirements of the gateway are as follows:
1) The gateway is required to support traffic control policy and QoS differentiation
according to the categories of traffic.
2) The gateway is required to provide mechanisms for performance measurement and
management.
– Communication aspects
The gateway is deployed between devices and communication networks and can use
different communication technologies (e.g., 3G, 4G, xPON, ZigBee, Wi-Fi and Ethernet) to
transfer data.
The communication related requirements of the gateway are as follows:
1) The gateway is required to support communication bridging between devices and
communication networks.
2) The gateway is required to support communications with at least one application.

3) The gateway is recommended to support multiple communication technologies to
interact with communication networks and devices and be able to enhance the
capabilities of the communication interfaces in case that the support of additional
communication technologies is required. In such case, the gateway is required to be
able to select the communication technologies according to the specific service
requirements.

8.2 Adaptation related requirements and recommendations

– Protocol diversity support
The gateway needs to communicate with devices and applications that may support
different protocols. The gateway should be able to load new protocols according to the
communication requirements.
The protocol related requirements of the gateway are as follows:

1) The gateway is required to support protocol translation between different protocols as
necessary when communicating with devices and applications.

2) The gateway is recommended to support dynamic protocol loading.
– Uniformity of interactions
The gateway is recommended to support uniform interaction with different devices and
applications in order to cope with their heterogeneity.
The requirements of the gateway related to uniformity of interactions are as follows:
1) The gateway is recommended to support uniform operations through standardized
protocols on devices which use different communication technologies.
