Abstract

The modern, optical bore metro and particularly core networks consist of multiple layers, where multiple different networking technologies are stacked one over the other. In this paper we assume an IP/MPLS layer over an DWDM layer, both controlled jointly by one vertically integrated GMPLS control plane. To better utilize network resources, smaller, upper-layer traffic streams are multiplexed into higher capacity wavelength paths in distributed way throughout the network. This is referred to as grooming.
