Technical Summary
RFC 8138 specifies the 6LoWPAN Routing Header (6LoRH),
compression schemes for RPL routing (source routing)
operation [RFC6554], header compression of RPL Packet
Information [RFC6553], and IP-in-IP encapsulation. This document
specifies a new Deadline-6LoRHE type for the 6LoWPAN Dispatch Page 1,
so that the deadline time of data packets can be included within the
6LoWPAN routing header. This document also specifies handling of the
deadline time when packets traverse through time-synchronized
networks operating in different timezones or distinct reference clocks.
Time synchronization is not mandated in this document, rather it points to
different available time synchronization solutions for low power and lossy networks.
Working Group Summary
Working group has provided many input towards development of the document during the initial phase before it is becoming a WG document.
Once these comments were incorporated into the document, the draft went for successful adoption call. After that two reviewers provided thorough comments including the shepherd.
Working group has a rough consensus to move this draft towards IESG submission.
