Hello Mario:
In practice, with the relatively simple way, the controlled flooding could just solve the problem of how to multicasting. We find it still a high-costing method to broadcast periodic Multicast IP packet(like Router Advertisement, RFC2461). So, more details about the up-layer protocol(especially about NDP) need be considered. For example, using an dynamic advertising algorithm to reduce the broadcast times.
Please refer to http://www.ietf.org/internet-drafts/draft-chakrabarti-6lowpan-ipv6-nd-01.txt For the IPv6 neighbor discovery multicast and signaling optimization in 802.15.4 networks. Thus we don't need multicast to work to run IPv6 on 802.15.4. This is simple to implement and does not require much additional code. This fits well with 802.15.4 network topologies. We have several presentations of this draft in last IETFs; the wg thinks this work is important enough to move forward. Please provide your comments. Will be also interested to find out if anyone is willing to implement this draft? Thanks, -Samita _______________________________________________ 6lowpan mailing list [email protected] https://www1.ietf.org/mailman/listinfo/6lowpan
