RE: Load Profiling Based Routing

["Dmitri Krioukov" <dima@krioukov.net>]

Hi Ibrahim,

I think those are quite interesting papers.

While leaving the question of their
usefulness to MPLS TE open, I think that
the answer to the question about their
usefulness to GMPLS/ASON would be
probably negative since LPR doesn't show
much more benefit when compared with MLR --
especially taking into consideration
that the relevant information about the
optical network state may be made precisely
known via the proprietary or standard extensions
to OSPF/ISIS. Best-fit seems to be the best fit :)

However, it would be interesting to see a review
of the most recent (heuristic) results in this
area as well as to hear other opinions...
