Dear all ;

Per our charter, we have to document an architecture that integrates IETF standards to make adoption of our common work easier for external standard bodies. From the start, we have identified 6LoWPAN ND and RPL as core elements to our architecture.

As we discussed in London and at most of the 6TiSCH calls since, there are a number of issues that we need to solve to facilitate this adoption. Some have to do with either protocol individually, and some have to do with the combined operations.

At the call last Friday, we ended up with the following list:

  1.  Should we support ND-only RPL leaves (missing TID) ?
  2.  Use and frequency of RA's from RPL routers
  3.  Use and frequency of NUD from RPL routers
  4.  Use of Target in efficient NS/NA - 6LoWPAN ND registeres the source not the target
  5.  Should RPL have its own DAD (today RPL needs ND for that)?
  6.  RFC 6282 unclear on compression of UDP after HbH header / RPL option
  7.  Could we use of Flow Label instead of HbH header
  8.  Misc:  Error codes, ZigbeeIP issues

After discussing to many people, it seems we need to refine these problems and then have topical calls about them. What I plan to do now is address the issues one by one, cc'ing the relevant WGs.

Any suggestion, idea before I start?

Cheers;

Pascal
