I do not think that's a fair representation. the main objection to 4rd-u is that it is 'just another translation' solution. how many do we need? it doesn't appear to offer any benefits compared to the already specified solution. as it stands it will just result in 3 ways of doing the same thing, instead of 2. the topic discussed in softwires, wasn't the main objection. as far as I can see, "checksum neutrality" does not offer any advantages over incrementally updating the L4 checksum. every node doing this will have to look into the L4 header anyway. cheers, Ole _______________________________________________ Softwires mailing list [email protected] https://www.ietf.org/mailman/listinfo/softwires
