METHOD AND APPARATUS FOR SCALING TRAFFIC ENGINEERING ROUTING IN A NETWORK
First Claim
1. A method for scaling Traffic Engineering, TE, routing in a network, comprising a plurality of network elements (nodes) connected in a given layer to each other via links,wherein contiguous TE domain segments, TE-SEGs, of a TE domain of said network are collapsed into virtual TE nodes, VN, each having an allocated TE domain unique identifier, VNID, and a detailed connectivity matrix, DCM, to provide a hierarchically virtualized network topology of said network.

Abstract
A method for scaling traffic engineering, TE, routing in a network, having a plurality of network elements (nodes) connected in a given layer to each other via links TE domain segments of a TE domain of said network are collapsed into a virtual TE nodes (VNs). Each VN having an allocated DE domain unique identifier and a detailed connectivity matrix, DCM, to provide a hierarchically virtualized network topology of the network.

- 9. An apparatus for scaling Traffic Engineering, TE, routing in a network comprising a plurality of network elements (nodes) connected in a given network layer to each other via links, is adapted to collapse selected by the operator arbitrary contiguous TE domain segments, TE-SEGs, of a TE domain of said network into virtual TE nodes, VNs, each having an allocated TE domain unique identifier, VNID, and a detailed connectivity matrix, DCM, to provide a hierarchically virtualized network topology of said network.
