Routing and Spectrum Allocation in Elastic Optical Networks: A Tutorial
IEEE Communications Surveys and Tutorials, 2015Flexgrid technology is now considered to be a promising solution for future high-speed network design. In this context, we need a tutorial that covers the key aspects of elastic optical networks. This tutorial paper starts with a brief introduction of the elastic optical network and its unique characteristics.

On routing and spectrum allocation in spectrum-sliced optical networks
2013 Proceedings IEEE INFOCOM, 2013The orthogonal frequency division multiplexing (OFDM) technology provides an opportunity for efficient resource utilization in optical networks. It allows allocation of multiple sub-carriers to meet traffic demands of varying size. Utilizing OFDM technology, a spectrum efficient and scalable optical transport network called SLICE was proposed recently.

Routing and Spectrum Allocation in Spectrum-Sliced Elastic Optical Path Networks
2011 IEEE International Conference on Communications (ICC), 2011Recently, the OFDM-based Spectrum-sliced Elastic Optical Path (SLICE) network attracts significant interests due to its elastic band-width allocation. The OFDM technology, on one hand, enables both sub-wavelength and super-wavelength traffic accommodation by allocating appropriate number of sub-carriers.

Routing and Spectrum Allocation
2016To properly analyze, design, plan, and operate flex-grid networks, the routing and spectrum allocation (RSA) problem must be considered. The RSA problem involves two basic constraints: the continuity constraint to ensure that the allocated spectral resources are the same along the links in the route, and the contiguity constraint to guarantee that ...
