Experimental Validation/Evaluation of a GMPLS Unified Control Plane in Multi-Layer (MPLS-TP/WSON) Networks
The demand for higher transport capacity driven by new packet-based services (e.g., HDTV) imposes strong bandwidth requirements to network carriers. Current transport networks, where IP is the convergence layer, do not scale due to the high cost of the opto-electronic interfaces and the consumed power. A more cost-efficient solution combines both; the Ethernet technology over Multi-Protocol Label Switching -Transport Profile (MPLS-TP) as the aggregation layer and the optical switching (Wavelength Switched Optical Networks, WSON) to offload the IP layer. A validation of the GMPLS unified control plane deployed within the ADRENALINE test-bed for dynamic provisioning in multi-layer networks is presented. The authors experimentally compare two on-line path computation mechanisms aiming at exploiting the grooming functions.
