Abstract
A method includes profiling user-network interface (UNI) ports including Optical channel Data Unit flex (ODUflex) in a network; and adapting, using a max-flow routing criterion, network-network interface (NNI) ports comprising ODUflex based on the profiling. A network includes a plurality of network elements; a plurality of links interconnecting the plurality of network elements, wherein the plurality of links includes Layer 0 Dense Wave Division Multiplexing (DWDM) bandwidth and Layer 1 Optical Transport Network (OTN) bandwidth; and a control plane operating between the plurality of network elements; wherein the Layer 0 DWDM bandwidth and the Layer 1 OTN bandwidth is statistically multiplexed using the control plane and manager based on monitoring bandwidth usage thereon over time.
