Were I the attorney, especially if the plaintiff had mentioned telephone number portability, I would ask the plaintiff to explain what additional work had to be done to the POTS network to implement portability. Should the plaintiff start mumbling, I'd impugn his credibility, and then ask a bunch of hard questions about SS7 (including the TCAP mechanism for portable number translation), how IP routing works, how IP routing has no authoritative mechanism for global translation, etc. I'd interrogate the customer about DNS and why they weren't able to solve their portability requirement with it. I'd look for detailed familiarity with RFC 2071 and 2072.Apples and Oranges. There is something called DNS which handles how hosts are "known" by. The whole reason behind DNS is so a user owns a name but doesn't matter what "number" they have. In the telco world you do not have this option since many businesses advertise their telephone number. (ie: yellow page ads, business cards, advertisements, etc.) When it comes to "the net" IP addresses are irrelevant as people are known by name, names which are transparently resolved to IP addresses. The technology exists so that people don't have to bring IP space with them. The routing tables are big enough as it is and the last thing we need is a bunch of judges comparing number portability to IP space portability. -- Robert Blayzor, BOFH INOC, LLC [email protected] PGP: http://www.inoc.net/~dev/ Key fingerprint = 1E02 DABE F989 BC03 3DF5 0E93 8D02 9D0B CB1A A7B0 Host System Not Responding, Probably Down.
