The IESG has received a request from the IPv6 over Networks of Resource-constrained Nodes WG (6lo) to consider the following document: - 'Packet Delivery Deadline time in 6LoWPAN Routing Header' <draft-ietf-6lo-deadline-time-03.txt> as Proposed Standard The IESG plans to make a decision in the next few weeks, and solicits final comments on this action. Please send substantive comments to the ietf@ietf.org mailing lists by 2018-12-24. Exceptionally, comments may be sent to iesg@ietf.org instead. In either case, please retain the beginning of the Subject line to allow automated sorting. Abstract This document specifies a new type for the 6LoWPAN routing header containing the delivery deadline time for data packets. The deadline time enables forwarding and scheduling decisions for time critical IoT M2M applications that need deterministic delay guarantees over constrained networks and operate within time-synchronized networks. The file can be obtained via https://datatracker.ietf.org/doc/draft-ietf-6lo-deadline-time/ IESG discussion can be tracked via https://datatracker.ietf.org/doc/draft-ietf-6lo-deadline-time/ballot/ No IPR declarations have been submitted directly on this I-D. The document contains these normative downward references. See RFC 3967 for additional information: draft-ietf-6tisch-terminology: Terms Used in IPv6 over the TSCH mode of IEEE 802.15.4e (None - IETF stream)
