I respectfully disagree with you on that. The solution that reduce the need of multicast in IPv6 already exists and it has been discussed in the working group many times in the past. Please refer to: draft-chakrabarti-6lowpan-ipv6-nd-04.txt There is a need for reducing multicast and broadcast in the reduced-power and low-processing ability devices that require to save power and do not want to wake up on multicast/broadcast messages - it is pretty clear in 802.15.4 network. The charter talks about the context of IPv6 where multicast is primarily used for solicitation and advertisement and that will have to be reduced since 802.15.4 is a shared network. I'll re-submit a revised draft before this IETF. -Samita _______________________________________________ 6lowpan mailing list [email protected] https://www.ietf.org/mailman/listinfo/6lowpan
