Yeah, that sounds like the germ of a Good Idea. The ANSI guys are probably right, more effort is required to design the monitoring/diagnostic tools we REALLY need. (But that doesn't mean we need a 17-layered management architecture before we can make any progress!). Here is another example of a testing paradigm we cannot handle now. In the testing Steve Casner and Mark Lambert have been doing across the Wideband Net ("Fatnet"), they have wished they could do "one-way pinging". That is, they wanted to collect the same data that a normal Mike Muuss pinger gets, but with no return trip, assuming they could access the hosts on both ends. Bob Braden
