[6lo] IETF 97 : Comments : draft-lijo-6lo-expiration-time-00.txt

["Lijo Thomas" <[e-mail]>]

Hi Thomas,
 
Thanks for your valuable comments during the draft <draft-lijo-6lo-expiration-time-00> IETF97 presentation
 
Your suggestion of including packet origination time along with the expiration time is very nice, as it conveys  very useful information to the intermediate nodes as well as the receiver to know how much time has already been elapsed. We will update the draft based on your suggestion. 
 
But I foresee an interesting problem when we include the packet origination time. While it is straightforward when the source and destination belong to the same time zone, it is tricky if they belong to different time zones, as the origination time will be invalid once the packet crosses over to network segments with different time zones. For instance, when the packet traverses across  2 LBRs belonging to different 6TiSCH networks due to different ASN time spaces. We plan to discuss our resolution to such scenarios in our draft.
  
Suggestions are most welcome !!!!
 
 
Thanks & Regards,
Lijo Thomas

Hi all,
We have submitted a new draft t <draft-lijo-6lo-expiration-time-00.txt> which proposes a new 6LoWPAN routing header type for conveying packet expiration time information.

has been successfully submitted by Lijo Thomas and posted to the

Revision: 00 
Title: Packet expiration time in 6LoWPAN Routing Header 
Document date: 2016-10-28 
Group: Individual Submission 
Pages: 11

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. 




Please note that it may take a couple of minutes from the time of submission 
until the htmlized version and diff are available at tools.ietf.org.
