Vint Cerf's latest columnmentions this too:


In a recent (April) report, one of the largest of the Japanese
international telecommunications carriers, KDD, reported that the
trans-Pacific circuit capacity allocated to Internet grew from 80
megabits/second to 536 megabits/second in the twelve month period
ending March 31, 1997. In the same period, telephone capacity expanded
to approximately 430 megabits/second up from 366 megabits/second.

At a recent Information Infrastructure workshop, Kenichi Kawaguchi
pointed out that the transmission capacity between Japan and the US for
Internet services (650 Mb/s) now significantly exceeds that for
telephony (400 Mb/s). See

I'd be interested in similar statistics from other places.
