            Packet expiration time in 6LoWPAN Routing Header
                   draft-lijo-6lo-expiration-time-00

Abstract

   This document specifies a new type to the 6LoWPAN Dispatch Page 1
   [I-D.ietf-roll-routing-dispatch] for carrying the expiration time of
   data packets within the 6LoWPAN routing header.  The expiration time
   is useful in making forwarding and scheduling decisions for time
   critical IoT M2M applications that need deterministic delay
   guarantees over constrained networks and operate within time-
   synchronized networks.

1.  Introduction

   Low Power and Lossy Networks (LLNs) could be employed for
   implementing real time industrial applications that require end-to-
   end delay guarantees [I-D.grossman-detnet-use-cases].  The
   Deterministic Network requires that data packets generated by the
   senders have to reach the receivers within strict time bounds.
   Including an expiration time information in the packets enables
   intermediate nodes to make appropriate packet forwarding and
   scheduling decisions to meet this requirement.

   The draft [I-D.ietf-roll-routing-dispatch] specifies the 6LoWPAN
   Routing Header (6LoRH), compression schemes for RPL routing (source
   routing) operation [RFC6554], header compression of RPI field
   [RFC6553], and IP-in-IP encapsulation.  This document specifies a new
   Timestamp-6LoRH type to the 6LoWPAN Dispatch Page 1 for including the
   expiration time of data packets within the 6LoWPAN routing header.
   In addition, this specification specifies handling of the expiration
