[6bone] 6bone routing stability improving?

[Ronald van der Pol]

I have used the MERIT 6bone routing reports to produce plots of some
long term (several years) trends of some parameters. See:

http://www.nlnetlabs.nl/ipv6/measurements/index.en.html

The first plot is the number of unique AS-es seen in the AS paths.
It is increasing exponentially.

The other plots are the number of announcements/withdraws per number
of total routes. Would that be a good measure of routing stability?
They have decreased significantly since about a year (these plots
have logarithmic Y axes).

Any suggestions for other useful plots?
