Dear Rollers,

In preparation for the modification of the DIS (DODAG Information
Solicitation), we are collecting the use cases.
We want to make sure we understand all the requirements before crafting a
solution.
Georgios has kindly prepared a document on the ROLL GitHub repo.
See a text rendition at
https://github.com/roll-wg/roll-dis-modifications-use-cases/blob/master/dra
ft-papadopoulos-roll-dis-modifications-use-cases.txt
Currently, the document has two use cases:
- a new node joins an established RPL network. The use case calls for a
fairly quick confirmation that the node has joined with a good quality
path. However, we don't want to reset the Trickle timers of all nearby
routers and trigger broadcast, since the use case is that just one new
node was added/replaced/rebooted.
- another use case is that several nodes join at about the same time (e.g.
electricity meters all reboot following power outage). We want the DIOs to
be sent with broadcast so that all joining nodes benefit from them.
The draft draft-thubert-roll-eliding-dio-information-03 has another
request for modifying the DIS. We'll soon incorporate it into the use
cases document.
If you have yet another need for modifications in the DIS, please tell us
what the use case is.
The intent is to publish the draft in time for presentation/discussion at
Vancouver.
Thanks

Dominique
