Re: [Roll] New Version Notification for draft-pkm-roll-nsa-extension-00.txt

Hello again,

To initiate the discussion over the ML before the IETF100, we would like to further motivate the use of our submitted draft (draft-pkm-roll-nsa-extension-00 "RPL DAG Metric Container (MC) Node State and Attribute (NSA) object type extension").

In an attempt to provide ultra-high reliability and ultra-low jitter performance in RPL-based networks, Packet Replication and Elimination (PRE) is a highly recommended scheme to employ.
Under PRE, each node forwards copies of a single data packet over different and congruent paths via different RPL parents.
In order to constrain the pool of alternative paths, an alternative parent among the list of possible parents need to be chosen. 
To this aim, a potential parent's parent set needs to be known. 
This draft defines how this information can be included and transmitted via DIO control messages.

Best,
Aris, Georgios, Nicolas and Pascal
