... breaks the end-to-end model of IP (as Imode and WAP do as they are
implemented today).
WAP does, but apparently i-Mode does not. The i-Mode vendors claim
that you can plug your laptop into your i-Mode phone in Japan (and get
speeds far faster than 9600 bps on newer phones), and someone on this
IETF list suggested that configuration provides internet access like
PPP in response to my questions here some weeks ago.
Would an actual i-Mode DoCoMo customer who has used such a
configuration please describe what it provides? TCP? UDP? ICMP?
How are connections maintained when radio contact is lost?
What kind of bandwith is typically observed, and under what conditions?
How are addresses assigned? Does it involve NAT?
