RE: [RAM] Ivip (was ViP ...) placement

["Joel M. Halpern" <jmh at joelhalpern.com>]

The note on the list comparing lvip with Mobile IP suggested a 
question in my mind.

In LISP. the TR (the device provides I and E functionality) is 
providing service directly to a specific set of customers.  Its 
capacity is tied to those customers, and it is operated either by 
those customers or by the ISP associated with those customers.  If we 
assume that there is value in having this, one can envision how the 
capability gets paid for.

If there is a rendezvous point somewhere off in the net, advertising 
a short prefix, and then disagregating that prefix into tunnels, that 
device is operated by someone.  But that someone is not the customer 
whose blocks are being advertised, nor is it the ISP serving those 
customers.  This leads to both authentication questions (how do you 
know this rendezvous box is allowed to issue that advertisement) and 
business model questions (how does it get paid for?

While conceptually decomposing the devices and separating the 
deployment is attractive, I fear that there are issues raised by such 
a separation that require attention.

Yours,
Joel
