None of the below events are related to network operations. Nordnog is.
If these are the dates that Nanog goes for, I assume that Nordnog will
have to reschedule. Nanog is large enough to attract people from all
over the world and the scheduling of Nanog influences a lot of peoples
agendas.
It should also be noted that the CAIDA study only examined the core
giant cluster of the Internet. In other words they only looked at the
most interconnected part of the Internet not the whole Internet. While
you could argue only the core matters, the methodological approach gives

Concerning latency
Well the bingo latency number used a lot in voice is

more important to have "consistent"

A much more real world example is in Heart medicine. I worked on a system
that used ds1's between hospitals. Say you have hospital A which is a
major institution and h ou have hospital B which is more remote and has
fewer skilled Doctors etc. Using a standard such as Dicom a Dr in
Hospital B.
