Hi Jonathan, I agree with you there - these nodes would *not* be participating in real IP or mesh forwarding.
However the ND process needs to function with these nodes. If we rely on 4861, these nodes which are going to miss packets must have a way to defend their address! -Colin -----Original Message----- From: Jonathan Hui [mailto:[email protected]] Sent: October 13, 2009 11:04 PM To: Colin O'Flynn Cc: 'Adam Dunkels'; '6lowpan' Subject: Re: [6lowpan] Fundamental concerns about 6lowpan ND Hi Colin, On Oct 13, 2009, at 2:56 PM, Colin O'Flynn wrote: > My concern for this sleeping method is very low power nodes.

They most likely won't be able to participate in forwarding/routing functions. Any bi- directional communication tends not to be end-to-end since they want to minimize round-trip time. -- Jonathan Hui _______________________________________________ 6lowpan mailing list [email protected] https://www.ietf.org/mailman/listinfo/6lowpan
