The design process for MPLS networks has much in common with design of any IP networks, but dimension the MPLS labelspace is one of the specific to MPLS networks.
PLS inherits the merits of both topology driven and flow driven label distribution scheme. It can greatly improve the performance of router when labelspace is constrained.
