Has anyone done any modelling of the likely effect of the new NSF sites
and of NSFnet on ARPAnet traffic/performance? Offhand, I would expect
that the changes (supercomputers with scientists all over the country
using telnet or tn3270 to get to them by ARPAnet, many more
NSF-supported hosts, and a new alternative backbone) are likely to have
massive effects on ARPAnet traffic patterns. It would be nice to know
that someone had given some thought before the fact to the potential
effects!

Similarly, has anyone modelled the effect of widearea and wideband
regional nets such as the planned NY-wide 1Mbit network (NYSERNET)?
