4. Label-controlled optical packet routing technologies and applications

Author

Koonen, A.M.J., Yan, N., Vegas Olmos, Juan José, Tafur Monroy, Idelfonso, Peucheret, Christophe, van Breusegem, E., Zouganeli, E., Koonen, A.M.J., Yan, N., Vegas Olmos, Juan José, Tafur Monroy, Idelfonso, Peucheret, Christophe, van Breusegem, E., and Zouganeli, E.

Abstract

An overview is given of various optical packet labeling techniques. The architecture and technologies are discussed for optical packet routing nodes using orthogonal labeling with optoelectronic label processing, and for nodes using time-serial labeling with all-optical time-serial label processing. An example of a nearterm application is given, and a comparison of routing technologies is made regarding their cost and reliability aspects.

17. An optical IM/FSK coding technique for the implementation of a label-controlled arrayed waveguide packet router.

Abstract

In this paper, we present a new concept of optical packet/burst switching suitable for generalized multiprotocol label switched (GMPLS)-based optical networks. In such networks, optical labeled switched paths are being established in a similar way as label-switched paths in MPLS. We use a wavelength label as well as an orthogonally modulated label, with respect to the payload modulation format, and which is encoded using either frequency-shift keying (FSK) or differential phase-shift keying (DPSK). Wavelength is used for switching in the node, whereas the orthogonal label defines the label-switched path. We present both simulation and experimental results to assess transmission performance of the proposed combined modulation scheme. In addition, we propose a suitable optical node architecture that can take advantage of this stacked label concept. Toward this, we use widely tunable wavelength converters to efficiently route IM/FSK (or IM/DPSK) optically labeled packets in an arrayed-waveguide grating (AWG)-based node structure. We present performance simulation results in terms of packet loss ratio and internal block probability. Internal blocking is an inherent problem of AWG optical routers, and a specific wavelength assignment algorithm has been developed to minimize it. Finally, the feasibility of IM/FSK transmission is experimentally demonstrated over an 88-km single-mode fiber span, and novel aspects of FSK generation and detection techniques are presented.
