The network layer of the IoT architecture includes all the network functionalities such as routing, transfer and path management (path selection and recovery) via a multipath infrastructure. This layer acts as a network infrastructure interconnecting the object network with the Cloud infrastructure.

The integration of QoS in this layer will enable the processing of the large volume of requests and information passing from the device layer to the support layer of the IoT architecture. This processing must be differentiated; in other words, it must prioritize the requests according to their importance. As a result, the QoS requirements for the network layer of the IoT architecture correspond to the QoS requirements of a network infrastructure while also adapting these requirements to the characteristics of the IoT environment. Various mechanisms, such as the prioritizing of requests and the choice of paths based on a QoS context, may be useful in meeting the requirements of the IoT.
