Steve,
Perhaps the growth rates you are interested in can be determined from the
series of RFCs summarizing Host Traffic Statistics (RFC 612 et al).
Cheers,
Alex

Thanks for the pointer to RFC 597.
As I looked at it, an aspect I hadn't considered before came to mind.
Installation of an IMP required provisioning 50 kb/s lines to two or three
other points. In the early days, we installed roughly a new IMP once a
month. (The lead time for ordering 50 kb/s lines from AT&T was NINE
months.)
Once an IMP was installed, new hosts could be added to the IMP as quickly
as the site could build or obtain the host-IMP interface and write or
obtain the software for their operating system.
If anyone has the dates for each of the hosts, it would be interesting to
compare the growth of IMPs vs growth of hosts.
