Dear Sudip
There are several different groups and companies working on algorithms for
optimizing primary, secondary and fast-reroute paths in MPLS-TE. Some
already have products to market.
Typical objectives include improving the predictability and performance of
delay-sensitive traffic, and improving network resilience, utilization and
maintainability. 

At Parc Technologies and our research centre in Imperial College, London, we
have found that constraint propagation and hybrid algorithm techniques are
effective at solving these problems. An algorithm combining this technology
with fast reroute provisioning has been incorporated into Cisco's MPLS
Tunnel Builder Pro to provide bandwidth protection as well as connectivity
protection in the event of link or node failures.
We can address further questions offline.
