Re: Risk of Internet collapse grows

The problem isn't so much the latency - although that is a problem.

Any researcher approaching this problem must understand that their result
are only as good as their data. In this case, assuming that Boardwatch
network maps are correct or, in fact, anything other than a marketing
fantasy, is a big problem.

Use of theses sort of data sources are extremely attractive to researchers
because they are straight-forward and lack the "well, but"'s of the
operational community. Trying to model real-life networks is much more
difficult because of the plethora of designs and exceptions involved -
very messy.

Richer industry/researcher partnerships could help with this. I suspect
the research community will have to become more aggresive in this area to
succeed.
