For its outstanding ability on constraint-based routing and multi-protocol encapsulation, more and more ISPs accept MPLS as fundamental technology for future networks.
This paper puts emphasis on the discussion of constraint-based routing, its mathematical programming model is given and several common optimization algorithms are illustrated.
