Function Selection Algorithm for Service Function Chaining in NDN

As the number of IoT devices increases with the popularity of IoT, the data traffic to and from IoT devices put a heavy load on the network and the cloud. In this work, to solve this problem, we consider deploying "functions" which process IoT data for IoT services on the calculation resources in the network, and by adapting Service Function Chaining (SFC) to these functions, we realize in-network processing of IoT data. Furthermore, in this research, SFC for IoT data will be realized using Named Data Networking (NDN), which is a content oriented communication protocol. In this scenario, we propose a novel function selection method in SFC that decides which functions will be assigned to the IoT service. In our proposed method, we aim to minimize the execution time of SFC while balancing the load of functions, and realize efficient SFC.
