Embodiments of the present invention are directed to a method and apparatus for the identification or discovery for properties of MPLS networks through a modeling technique. Aspects of the present invention provide for discovering or identifying the Label Switched Paths in MPLS networks. The method comprises the steps of representing a network by a model comprising a plurality of configuration non-specific first object classes that are representations of types of components associated with the network components, and a plurality of configuration non-specific second object classes that are representations of relationships among the representation of types of component, identifying instances of a first one and a second one of the types of components object class, and identifying the label switch path by traversing the instances of the first and second types of components object classes through select ones of the relationship object classes associated with the first and second type of components object classes.
