Making your phone number stay the same no matter whether you're a PacBell or MFS or TCI customer is exactly the same problem as making IP addresses portable... just wait until ISPs are regulated, and they get the same mandate. -matthew kaufman matthew () scruz netNot quite. If I move today from San Francisco to San Jose, I have to renumber because of area codes. This provides first level hierarchy, which the Internet doesn't have (actually second, country codes are the first). The phone companies also have settlements worked out, such that a cutout costs the group getting the cutout, not the group who has the base or the IXC. Phone routing are vastly more restrictive than IP routing. Jerry -- End of excerpt from Jerry Scharf
1. If everyone in area code 213 (for instance) decided to exercise number portability and move their existing number to a new provider, that'd be about 3.7 million "host routes" with NO possibility of aggregation. That's far more routes than are in my border routers (by about 100X) (Presumably CAPs in LATAs with lots of area codes are going to want to hold internal routes for ALL of the local area codes, so they can do complete bypass... in the Los Angeles area that'd at least quadruple this routing table requirement) 2. The costs of portability in the latest proposals I've read are to be shared between the existing and the new providers, with the visible end-user cost of "keeping your number" relatively low 3. It may be technically stupid, but it is what consumers want, and the PUC and FCC are on their side. I still won't be surprised when the "number portability" precedent gets picked up by a regulatory agency and forced on the Internet, at least within the United States. -matthew kaufman matthew () scruz net
