[ NNSquad ] 911 vs Airplanes?
The VoIP liability message is completely wrong!!!! Remember that the mere appearance of a 9-1-1 call attempt is signal and that can get through an IP network with redundant paths more reliable than over a system that requires miles of copper pairs stay intact in an emergency. Of course IP over that copper pair is a problem -- but that's what happens when ask a telephone company to design a reliable system -- they paste QoS stickers everywhere and then say that failures simply don't count. People have died because of VoIP reliability -- or, more to the point, because cellular systems insist on voice or nothing so you can't get out a life-or-death message because you don't get "pin-drop" quality voice. This is a fatal (literally) flaw in the QoS model -- some third party knows without any doubt what a valid message is and isn't. Thus we have a brittle 9-1-1 system only available to those able to dial a phone that they happen to be near in any emergency and it goes to a dispatcher who has one try at getting it right. We've become inured to the fatally flawed systems we use now and declare everything else to be wrong no matter how much better it really is. I don't want an ISP's intelligent design mentality to cost me my life because of the presumption that POTS is, by definition, the only reliable means of communications. You should also read the book, Fatal Words, about airline crashes caused by this same attitude in aviation. If ISPs claim that they must give voice priority to save lives then they must take responsibility for the deaths they cause by preventing other means of communicating. -----Original Message----- From: email@example.com [mailto:firstname.lastname@example.org] On Behalf Of Lauren Weinstein Sent: Wednesday, March 12, 2008 17:09 To: Brett Glass Cc: Lauren Weinstein; email@example.com Subject: [ NNSquad ] Re: Moderation policy (and previous message from Brett Glass) Let's get past the airline bomb analogy. A bomb's sole purpose is to destroy and terrorize, and whatever "damage" is done by P2P is ancillary to P2P's purpose, not P2P's purpose itself. When someone triggers a purposeful DDoS attack, that's damage for damage's sake. But Brett's concern about VoIP liability is a valid one, though I tend approach the question from a different angle. The trend in the VoIP industry seems to be toward disclaiming any responsibility for handling emergency calls reliably -- in some cases I've even seen stickers on VoIP phones warning that they shouldn't be used for emergency purposes. Much of this issue has revolved around E-911 capability problems, but concerns about VoIP availability under heavy load (either due to the emergency itself or other factors, such as overall Internet traffic characteristics at any given point in time) have increasingly been noted. Since most Internet access networks are not engineered to traditional telco POTS availability standards, the risks of emergency calls on most consumer or enterpise VoIP systems can be considerable. For that matter, in serious regional emergencies, even conventional POTS can fail. Having lived in L.A. my entire life, I can testify to the range of riots, fires, landslides, earthquakes, and other biblically-inspired disasters locally where I've seen all my phone and Internet circuits go down. And that's not counting the guy who ran his car off the street and sheered away my local B-box. Which brings us to an interesting question. Is it even reasonable to be considering the use of VoIP for emergency calls in the current Internet environment, given the wide variety of factors that come into play (including but not limited to QoS considerations)? --Lauren-- NNSquad Moderator - - - Brett Glass wrote: > Yes, I know that to some who don't operate networks for a living the > analogy might seem "over the top."
