Reed'" <dpreed () reed com>, Richard Shockey <richard.shockey () neustar biz> Subject: RE: [IP] more on WIRELESS CARRIERS PROPOSE NEW 'NUMBERPORTABILITY' PLAN We already have IP address portability! It's called the DNS. The problem is that people remember the old days when the IP address was really an address and not a routing path or circuit ID. This is also my problem with IP mobility -- it is like trying to provide reliability at the IP layer rather than the TCP layer. The persistent connections should be defined at the layer above IP between end point identifiers. The DNS can serve as source of identifiers, especially since it maps those to IP addresses. There may be a reason for some local mapping of IP addresses among a set of proximate end points but trying to create a new mechanism for IP mobility is akin to creating another DNS focused on the accidental properties of one application when the current DNS address the issue. (I can go into more detail if there is interest). While I welcome cell phone portability it is a special case that diverts attention from a simpler approach already being proposed. Once again the cellular phone industry is trying to create its own mechanisms that presume there is some special about cell phones. Maybe there is since special is a euphemism these days. Using the DNS (ENUM) to translate phone numbers is far simpler. The problem is indeed political since if the ITU doesn't manage to lockdown the complete hierarchy then it becomes too easy to leave the PSTN (not just jump to another carrier) and there would be little reason not to. Imagine having your own NS records in the ENUM space -- you could define your own local phone numbers and to your own follow-me implementation. Free phone calls are a minor threat compared with the ability to redefine telephony to be much more useful and effective. The only thing interesting is that the "names" would be limited to digits on phones as an accommodation to legacy devices with legacy interfaces. ILECs realize that this is extremely threatening since the only reason they exist is the difficulty of interconnecting the PSTN to user-defined VoIP. Unlike the RIAA there is surprisingly little outrage enough the economic consequences are far far worse. I guess it's too hard for most people to recognize that telephony is a trivial app. Given all this I guess I do need to belabor the point that the problems with the DNS are largely due to the secondary and flawed agendas (meaning and authority) rather than the mechanism itself (though it is far form perfect). ------ End of Forwarded Message ------------------------------------- You are subscribed as interesting-people () lists elistx com To manage your subscription, go to http://v2.listbox.com/member/?listname=ip Archives at: http://www.interesting-people.org/archives/interesting-people/
