We present a novel optical orthogonal frequency division multiplexing (O-OFDM) scheme, suitable for intensity-modulated direct-detection systems, where the modulation/demodulation processing takes advantage of the fast Hartley transform algorithm. Du

In the evolution from opaque networks, using 3R regenerators and OEO conversions for every wavelength channel, towards transparent networks, relying on end-to-end all-optical connections, translucent networks is considered as an intermediate step. A

Experimental demonstration of ASON-GMPLS signaling interworking in the NOBEL2 multi-domain multi-layer control plane emulator

Autor: C. Cavazzoni, Ramon Casellas, R. Muoz, Hans-Martin Foisel, C. Garcia, H. Dentler, Roberto Morro, S. Pizzaja, Monika Jaeger, Ricardo Martinez, J. Jiminez

Publikováno v: 2008 International Conference on Optical Network Design and Modeling.

Both the OIF and IETF inter-domain interfaces for control plane enabled networks are based on GMPLS protocols. OIF interfaces include ITU-T/ASON specic extensions, resulting in interoperability issues. Moreover, the connection services considered by

Experimental shared path protection algorithms in distributed all-optical GMPLS-based networks

Autor: R. Muoz, R. Casellas, Ricardo Martinez, Jaume Comellas, Gabriel Junyent

Publikováno v: 2007 6th International Workshop on Design and Reliable Communication Networks.

This article focuses on the problem of dynamic and distributed shared path protection (SPP) in all-optical GMPLS networks without wavelength conversion capability. In this scenario, both working and backup lightpaths use a single wavelength for all l
