Flexible IoT Datapath Programming using P4
share
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.
