In the recent years, telecom and computer networks have witnessed newconcepts and technologies through Network Function Virtualization (NFV) andSoftware-Defined Networking (SDN). SDN, which allows applications to have acontrol over the network, and NFV, which allows deploying network functions invirtualized environments, are two paradigms that are increasingly used for theInternet of Things (IoT). This Internet (IoT) brings the promise tointerconnect billions of devices in the next few years rises several scientificchallenges in particular those of the satisfaction of the quality of service(QoS) required by the IoT applications. In order to address this problem, wehave identified two bottlenecks with respect to the QoS: the traversed networksand the intermediate entities that allows the application to interact with theIoT devices. In this paper, we first present an innovative vision of a "networkfunction" with respect to their deployment and runtime environment. Then, wedescribe our general approach of a solution that consists in the dynamic,autonomous, and seamless deployment of QoS management mechanisms. We alsodescribe the requirements for the implementation of such approach. Finally, wepresent a redirection mechanism, implemented as a network function, allowingthe seamless control of the data path of a given middleware traffic. Thismechanism is assessed through a use case related to vehicular transportation.
