Hi Anders and Mukul:

 

For RPL, we probably need more than one bit. RPL needs a TID, and an instance 
ID will help quite a bit in some cases if the app is aware of it.

Other routing protocols might benefit from other information to improve their 
operation.

Once we figure what the abstract information is, then we'll probably have to 
define a way to carry that information from the host to the router.

Might be ND, but other people have already started a packetBB / RPL interwork, 
so at this point I do not know.

 

Cheers,

 

Pascal

(maybe not so surprising, )

I would like to support Mukul.

 

RPL is one routing protocol, but 6LoWPAN may run under any routing protocol - 
or none at all.


In all cases, a sleeping node can benefit from asking a neighbor router to 
provide connectivity to that node.
To me this definitely sounds like a feature that belongs to the 6LoWPAN ND 
toolbox.

 

Thanks,

  Anders

I agree absolutely.

I agree. That's why I think 6lowpan ND should provide a mechanism to clearly 
identify a registered neighbor as a 6lowpan host or a 6lowpan router.

Thanks
Mukul

Hosts don't take part in routing protocols, so I don't understand this sequence.
The only source of information about reachability and network configuration a 
host has is ND (and DHCP for some of the latter, if present).

Gruesse, Carsten
