In this paper we propose two new approaches that jointly perform, on the one hand, routing and wavelength assignment (RWA) and, on the other hand, either tuning the signal power of certain Wavelength Division Multiplexed (WDM) channels or grooming the traffic of some WDM channels in nodes that are grooming capable. We evaluate the proposed optimization methods for both, single and multilayer networks. In the first case we assume that no signal regeneration is allowed along the path, only reamplification, while in the more complex two-layer case we assume grooming in the electronic layer that implicitly performs 3R signal regeneration and wavelength conversion as well.}, keywords = {Optimisation; Grooming; Routing; physical impairment; power level}, year = {2008}, pages = {162-165} } @inproceedings{MTMT:2622807, title = {Restoration of Multi-Cast Trees in Optical-Beared Grooming-Capable Two-Layer Networks}, url = {https://m2.mtmt.hu/api/publication/2622807}, author = {Cinkler, Tibor and Perényi, Marcell Ádám and Soproni, Péter Balázs}, booktitle = {2008 10th Anniversary International Conference on Transparent Optical Networks, ICTON 2008}, doi = {10.1109/ICTON.2008.4598644}, unique-id = {2622807}, abstract = {We consider dynamically changing multicast trees (light-trees) in two-layer optical-beared grooming-capable networks. The continuous changing of the tree ?leaves? causes the degradation of the tree in time. Therefore, a huge amount ofnetwork resources can be spared by reconfigurations performed periodically or upon failures and reparations. In this paper we focus onto restoration of trees if a link (or any other network element) fails. The failures are more critical if they affect the tree closer to its root, while less critical if closer to a leave. We propose and evaluate four simple restoration strategies and investigate their performance for different multicast routing algorithms.}, keywords = {reconfiguration; multicast; optical network; WDM}, year = {2008}, pages = {14-18} } @inproceedings{MTMT:2622805, title = {ILP Formulation of Signal Power Based Routing for Single- and Multi-Layer Optical Networks}, url = {https://m2.mtmt.hu/api/publication/2622805}, author = {Perényi, Marcell Ádám and Zsigmond, Szilárd and Cinkler, Tibor}, booktitle = {BROADNETS 2008 - Fifth International Conference on Broadband Communications, Networks and Systems}, doi = {10.1109/BROADNETS.2008.4769154}, unique-id = {2622805}, year = {2008}, pages = {632-639} }
