So because Radia Perlman wrote what she wrote 2 years ago before most of
these new hardware improvements were utilized by vendors, you could say that
what she really did in her book was to correctly predict the future - that
MPLS would have little speed advantage, and therefore would be used for
traffic-engineering and VPNs (which I think is just another form of
traffic-engineering).
Then again, if anybody in the world has networking ESP (psychic friend's
networking?) , Radia Perlman would be the one.
