[Detnet-dp-dt] Quick notes from 4/11/17 call

[Jouni Korhonen <[e-mail]>]

Present: Jouni, Janos, Balazs, David, Loa, Norm, Yuanlong

Agenda:
* recap of the IETF98 corridor discussions & descisions
* list of things to do

Discussion & decision:
* Jouni sent out RFC6621 pointer for Simplified Multicast Forwarding that does duplicate detection and elimination
* Solutions draft:
 - update the PW encapsulation i.e., no Flow-ID and incoming PW labels have to be the same to trigger the duplicate detection. 
 - IPv6 use flow label for detnet flow identification, new extension header for seqnum.
 - on IPv6 path stitching policy routing, multicast with with proper distribution tree and segment routing were discussed as possible alternatives instead of tunneling. Needs more discussion.
 - no good solution for IPv4. Just left it out. One can use PWs to transport IPv4 as a packet PW.
 - CoS/QoS update to be done. CoS is “easier” to start with.. first describe how the TC or DSCP bits need to be brought all the down to the most outer level.
* Alternatives draft (now expired):
 - update the conclusions to state PW + IPv6 (native IP mode) are way to go. No good solution for IPv4.
* Problem Statement:
 - Norm will ship an update.
* Webex time will change. It will be Tuesday 6AM Pacific starting from next call.
* solutions and alternative draft updates hopefully out this week.

Next call:
 no call next week 4/18/17.
