Packet Delivery Deadline time in 6LoWPAN Routing Header
draft-lijo-6lo-expiration-time-04

There seems to be some healthy level of interest and even an implementation in OpenWSN.

Expressions of support:
• Tianran Zhou
• Zhangmingui (Martin)
• Pascal Thubert (pthubert)
• Shalu
As an implementer of the draft in OpenWSN platform, I support the adoption.

The packet expiration will help in meeting delay constraints in a deterministic network. For real time applications,
the expiration time information will help not only in making delay sensitive scheduling decisions, but also discard
those packets which have crossed the deadline thereby saving bandwidth and energy in a LLN.

• +1. I have been following the draft as part of usecases for draft-ippm-ioam-data and seen the reference implementation. I think it is relevant and the solution specified here is a good start for deadline driven routing in IOT.
• Anitha Varghese
The deadline-6LoRH can be very useful in IoT and factory automation applications over wireless. This will enable deadline based routing and scheduling, real time wireless networks etc. I support the adoption of this work.

This document has been discussed at face to face meetings as well as on the list. There is some reasonable interest and an implementation in OpenWSN. Per the last meeting, after a revision we would issue a call for adoption, and are pursuing now.
