[ih] state of the internet probes? (was Re: AOL in perspective)

[Jack Haverty]

Right, SNMP came later, as a "Simplified" version of NMP - Network 
Management Protocol, which may have only existed in email discussions.

IIRC, the earliest work on Internet management was done by David 
Floodpage as part of the "make Internet 24x7" work, and documented in 
some IENs, e.g., https://www.rfc-editor.org/ien/ien132.txt

All that led eventually to SNMP, which is what is most likely to be 
recognized today.
