While I agree with the sentiment, it's maybe worthwhile to remember the rationale[/ization] for requiring a checksum: IPv6 does not have a header checksum, and the UDP checksum (which, as does the TCP checksum, covers the IPv6 pseudoheader and thus some of the more important header fields no longer protected by the IPv4 header checksum) is the only checksum that guards against misdelivery of packets. Of course, this architectural concern has to be weighed against other concerns, including implementation issues, as well as the fact that the v4/v6 asymmetry adds one more real-world IPv6 deployment issue. Just one data point here. Gruesse, Carsten _______________________________________________ 6lowpan mailing list [email protected] https://www.ietf.org/mailman/listinfo/6lowpan
