I have a few questions: Section 4., paragraph 15: > * Classes of Service: > For mixing applications of different criticality on one > LoWPAN, support of multiple classes of service may be required > in resource-constrained LoWPANs and may require a certain > degree of routing protocol overhead. I'm not sure I see why. QoS support typically involves end-to-end transport functions and more complex *queueing*, but not routing *protocol* overheads. Could you explain? Section 4., paragraph 17: > b. Node Parameters: Isn't queuing strategy and queue buffer size also a parameter? Section 4., paragraph 21: > * Traffic Pattern: > This parameter affects routing since highly loaded nodes > (either because they are the source of packets to be > transmitted or due to forwarding) may contribute to higher > delivery delays and may consume more energy than lightly > loaded nodes. This applies to both data packets and routing > control messages. Again, I'm not sure I understand. Why does the volume of application data sent or received by some nodes affect the routing *protocol*?

I remain unhappy about the objective of this document within the IETF since it seems to be capturing requirements for routing in a 6lowpan that form a subset of the requirements already documented and addressed by the ROLL working group. Nevertheless, since my gripes are mainly about process, I am taking them out of my Discuss so that the document can proceed. I would still be happy to have it clarified to me how this document fits in with the ROLL effort.

Is there an example of a power affluent node that is *not* mains-powered? And does this have any impact on the routing requirements?
