We propose a novel monitor placement algorithm that reduces significantly the number of monitors required to accurately assess the QoT of all lightpaths established in an optical network, compared to other monitor placement methods.
This paper evaluates a centralised impairment-aware path restoration approach for GMPLS-controlled transparent optical networks. Experimental results on a 14-node network test-bed show successful QoT compliant path restoration of around 3.6 seconds.
Transparent optical networks are the enabling infrastructure for converged multi-granular networks in the future Internet. The cross-layer planning of these networks considers physical impairments in the network layer design. This is complicated by the diversity of modulation formats, transmission rates, amplification and compensation equipments, or deployed fiber links. Thereby, the concept of quality...
