RWA parameters and algorithms taking into account QoT
Under this topic, two different collaborative research actions have been performed with European and Japanese R&D institutions. In both actions, the common goal was to introduce impairment-awareness in wavelength-routed networks with non-ideal optical layers. All-optical transport networks were chosen as the paradigm for this work, because these networks do not have opto-electronic conversions in the core nodes of the network, and therefore physical optical links are not isolated. That is, on the one hand the optical signal is not regenerated at every node, and on the other errors and impairments propagate in the network.
Impairment-awareness has been tackled primarily in the lightpath setup process, more precisely in the form of impairment-aware Routing and Wavelength Assignment (RWA) algorithms performed by a control plane, e.g., the Generalized Multi-Protocol Label Switching (GMPLS), and in the definition and measurement of quality-of-transmission (QoT) parameters and physical-layer models to estimate and validate QoT for impairment-aware RWA.

Cooperation Agreements
National Institute of Information and Communications Technology (NICT)
- On May 21st 2008, The CTTC has signed a cooperation agreement with the NICT of Japan to develop scientific research projects in the optical networking field. By means of this agreement the previously established relations among the two institutions are consolidated. The first point of contact took place in 2006, with the postdoctoral stay of the researcher Dr. Carolina Pinart at NICT. Successively, in January 2008, the 2-year International Complementary Action GAUDI Design and study of GMPLS algorithms and monitoring techniques for intelligent wavelength-routed Networks started, led by Dr. Raül Muñoz. In the framework of this action, during April 2008, Dr. Hiroaki Harai, responsible for the Optical Grid Infrastructure Project, carried out a stay at CTTC and Dr. Ramon Casellas, researcher of the CTTC, is currently visiting NICT. The Optical Grid Infrastructure project is part of the Network Architecture Group of NICT, formerly led by Dr. Masaki Hirabaru and currently led by Dr. Hiroaki Harai (since September 2008)..
