Oh, 'experience' is never a good play; after all, all experience is ultimately anecdotal. But as an argument, it's being used by all sides. We haven't seen missent traffic errors, because we're not looking for them. The question is, what does the end-to-end argument support? And surely the burden of proof falls on those making the change (this draft); first, do no harm. The end-to-end principle and the precautionary principle are strong arguments. Stone's papers, though technologically dated, support the underlying principle and provide analysis - you want a modern setting, I'm quite happy with proof of principle. Weird stuff happens; an end-to-end check can catch it.

Many people on this list, and certainly a few of the ones you've been directly arguing with, have no small amount experience running *extremely* large, geographically distributed networks. I've spent a bit of time running some very large backbones and major content providers myself, and I have to say, I'm finding most of your arguments here to be unconvincing at best. I do find it a bit ironic that you're asking for (difficult to gather, vendor variable and generally poorly documented) data form Stewart, when your own argument has yet to be substantiated via any form of quantitative impact analysis, either empirically or theoretically in a modern setting. I'd be interested in seeing empirical (back)scatter collection data (similar to what Morley or Savage have done) to get some idea of impact here. I strongly suspect that corruption scatter will be trivial, and certainly completely overwhelmed in terms volume by typical, day to day DDoS backscatter. Perhaps this may be an idea for your next research paper? With regard to the congestion-control-of-all-tunnel-protocols argument: I find the argument to be specious. Curtis summed up the end-to-end version of this argument pretty succinctly in an earlier email, to wit: If congestion aware or using a congestion aware transport, the top level applications are still congestion aware. If congestion ignorant, they are still congestion ignorant. If hostile, they are still hostile.

If a NAT gets a corrupted header, won't it open up new state and attempt to translate for that header? Remember, this is UDP, not TCP - it's not on an existing connection that must have already been opened by SYN/ACK, where the NAT is more likely to reject it as unknown. 'NATs, which rewrite and can trash headers, demonstrate and validate the integrity of the Internet' is not a good argument imo. I'd like to see some evidence for '"obscure" IP protocol numbers will get dropped by default at NATs and firewalls.'. IP/GRE is relatively state-free, nothing much to translate at transport there - it's not SCTP. I've spent a couple of years running an ISP, and the 'oh, that protocol won't go through your NAT' has not come up.

Everything encapsulated with "obscure" IP protocol numbers will get dropped by default at NATs and firewalls, whereas UDO traffic happily traverses them. The reach of UDP traffic is much broader. > > Lars So we have established that it's not the load on the NATs and Firewalls we are worried about. Seemingly from the above congestion is off the table as well. Now surely those same NATs and firewalls will be looking for an SA, DA, Type, SP, DP match and that is a lot of things that have to be right for a header corruption misdelivery to get through. - Stewart _______________________________________________ mpls mailing list mpls@ietf.org<mailto:mpls@ietf.org> https://www.ietf.org/mailman/listinfo/mpls
