6TiSCH centralized scheduling: When SDN meet IoT

Abstract

The Deterministic Networking paradigm, which is prevalent in Operational Technology (OT), is now getting traction at the IETF and the IEEE, to enable the convergence of OT with Information Technology (IT), and the Industrial Internet vision, whereby the automation world can leverage IT technology to optimize OT processes. New Working Groups (WGs) are now emerging at the IETF to develop new routing and resource allocation schemes for IPv6/MPLS-based deterministic Layer-3 networks. In this work, we present the challenges that the DetNet and the 6TiSCH efforts will be facing to enable that convergence, particularly how DetNet can apply Software Defined Networking (SDN) centralized methods to provide global optimizations, and how 6TiSCH can reuse and extend the DetNet work for LowPower Wireless Sensor Networks (WSNs).
