[Roll] Scalability of P2P-RPL

[Ulrich Herberg <[e-mail]>]

Hi,

as I mentioned today on the microphone, I would be interested to see
results of the different deployments in terms of performance, overhead,
delay, required state etc.

Section 2 ("The Use Cases") says that:

   Another use case, common in a commercial building environment,
   involves a large LLN deployment where P2P communication along a
   particular DAG among hundreds (or thousands) of routers creates
   severe traffic congestion near that DAG's root, and thus routes
   across this DAG are desirable.

I don't see anywhere in this section that the draft is only limited to 4-5
hops, as mentioned today. If the protocol can run in larger networks but
only for routers in maximum hop distance of 4-5, that should be spelled out
(together with a warning that TTL of the control messages has to be set to
4-5 to avoid network wide flooding).

Regards
Ulrich
