Packet Delivery Deadline time in 6LoWPAN Routing Header
draft-ietf-6lo-deadline-time-05
Abstract
This document specifies a new type for the 6LoWPAN routing header
containing the deadline time for data packets, designed for use over
constrained networks. The deadline time enables forwarding and
scheduling decisions for time critical IoT machine to machine (M2M)
applications that operate within time-synchronized networks that
agree on the meaning of the time representations used for the
deadline time values.

1. Introduction
Low Power and Lossy Networks (LLNs) are likely to be deployed for
real time industrial applications requiring end-to-end delay
guarantees [I-D.ietf-detnet-use-cases]. A Deterministic Network
