—We design and implement a multicost impairment-aware routing and wavelength assignment algorithm for online traffic. In transparent optical networks the quality of a transmission degrades due to physical layer impairments. To serve a connection, the proposed algorithm finds a path and a free wavelength (a lightpath) that has acceptable signal quality(More)
We consider the offline version of the routing and wavelength assignment (RWA) problem in transparent all-optical networks. In such networks and in the absence of regenerators, the signal quality of transmission degrades due to physical layer impairments. Because of certain physical effects, routing choices made for one lightpath affect and are affected by(More)
—We propose and evaluate an impairment-aware multi-parametric routing and wavelength assignment algorithm for online traffic in transparent optical networks. In such networks the signal quality of transmission degrades due to physical layer impairments. In the multi-parametric approach, a vector of cost parameters is assigned to each link, from which the(More)
—In transparent and translucent wavelength routed optical networks the signal quality degrades due to physical layer impairments while the interference among lightpaths implies that routing decisions for one lightpath affect and are affected by the decisions made for other lightpaths. To establish a lightpath for a new connection two main approaches can be(More)
