Patent ID: 7944857

Claim:
A method for deriving a path of a traffic engineering tunnel in a network using Multi Protocol Label Switching, MPLS, traffic engineering and a Management Information Base, MIB, describing managed objects of the network, the method comprising: obtaining node connectivity information from the MIB; obtaining network connectivity information from a network node manager; and deriving tunnel path information based on the node connectivity information and the network connectivity information, wherein the tunnel path information is obtained from at least one of a first object describing actual hops traversed by a path between nodes of the network and a second object describing computed hops traversed by a path between nodes of the network, wherein deriving tunnel path connectivity information comprises: determining if the second object is present in the MIB; and if it is determined that the second object is present in the MIB, obtaining information from the second object in preference to obtaining information from the first object.
