sure, but still how does the application and user know that their 'thing they are doing' is broken, why it's broken and how to fix it? Keep in mind that today this all works and users don't have to understand 'checksum' or 'udp' or 'ip version'... tomorrow something (hopefully) seemless will happen and their 'thing they are doing' will just keep on working. Spurious failures as would be happen in this proposal will be problematic, and will (again) cause hesitance in deployments. > off by default are dead by now. linux nfs doesn't do (nor does netapp apparently) checksums on udp nfs today (current 2.6 linux kernel, ubuntu 8.x) -------------------------------------------------------------------- IETF IPv6 working group mailing list [email protected] Administrative Requests: https://www.ietf.org/mailman/listinfo/ipv6 --------------------------------------------------------------------
