There are a number of parameters that determine the performance of a
connection.  1-way-delay and loss are two of them.  Bandwidth, delay
variations are others, and I can come up with a few more.  Depending on
your application, you have to decide which one is the most important.  For
example, bandwidth and losses are the most important parameters for FTP,
delay for interactive work, delay variations for "streaming" applications
(voice over IP), and so on.  

Besides that, lots of networks specify the delays between points and are
sold on that basis.  The Test-Traffic project provides a way to actually
measure them.

We're certainly looking at "Summary pages", "Internet weather maps",
"Executive summaries"  or whatever you want to call them.  However, these
are one of those things that everybody seems to be talking about but
nobody seems to be able to define what should be in those plots. I'd love
to get some feedback on what people want to see on a summary page.

But what if a customer calls and complains that "the net is so slow".  At
that point you want to give him the URL to show where the problem is.

The Committee (...) was unable to reach a consensus that substantial merit was
lacking. Thus, the appeal was deemed meritorious.          (Orlando NABC #19).
