Flexible IoT Datapath Programming using P4 (2006.15782v1)

Abstract: The progress of the network and device technologies enables any device to be connected to the Internet thereby forming an Internet of Things (IoT) architecture. Internet-related activities based on the IoT services can inevitably generate a lot of real-time data which leads a big data phenomenon. To efficiently handle such big IoT data, software-defined networking (SDN) techniques could come into play. Among SDN techniques, P4 is a highlevel language for programming protocol-independent packet processors. This paper presents our preliminary work on how we can use P4 to achieve flexible datapath programming for large scale IoT streaming data streaming. As a case study, we describe the implementation of dynamic MST-based datapath programing for IoT data collection in an arbitrary network topology.
