I believe this is referred to as "velocity factor".

I asked about this article to someone who works on optical properties
of materials. Here's what he says (I don't pretend to understand
everything though):
" This is called superluminal propagation, and many groups have shown
it in different media; this one is in fiber. However, this does not

No, they were actually over the speed of light for a "portion of the
signal":
"They were also able to create extreme conditions in which the light
signal travelled faster than 300 million meters a second. And even though
this seems to violate all sorts of cherished physical assumptions,

Okay, guess I should have read the article first, given the title is "Light
that travels faster than the speed of light"

Well, I would imagine that the faster you can ship the bits,
the faster anything can happen -- including BGP convergence and
botnet attacks (too!). :-)
Yeah, I realize that the possibility to actually "speed up"
light via the optical transmission systems may be a long

To make this operational, will this speed up BGP convergence?
(note that there is a difference between group velocity
and phase velocity. The posters of "300,000 Kilometers Per
Second. It's Not Just a Good Idea, It's the Law!" are still
valid).
