Elastic Spectrum Allocation for Time-Varying Traffic in FlexGrid Optical Networks
IEEE Journal on Selected Areas in Communications, 2013Elastic flexgrid optical networks (FG-ON) are considered a very promising solution for next-generation optical networks. In this article we focus on lightpath adaptation under variable traffic demands in FG-ON. Specifically, we explore the elastic spectrum allocation (SA) capability of FG-ON and, in this context, we study the effectiveness of three ...

Robust spectrum allocation in elastic flexgrid optical networks: Complexity and formulations
Networks, 2017 Flexgrid optical networking technology allows for a more flexible consumption of bandwidth. The spectrum allocation problem consists of the conflict‐free assignment of consecutive spectrum space of different sizes to lightpaths. In this article, we study the computational complexity of spectrum allocation with and without demand uncertainty.

Spectrum allocation scheme considering spectrum slicing in elastic optical networks
Journal of Optical Communications and Networking, 2021Recent advances in physical layer optics have made slicing of optical bands into multiple subbands with different bandwidths possible. Due to this development, spectrum allocation has become easier in elastic optical networks (EONs). More specifically, owing to the slicing technology, the defragmentation problem in EONs can be addressed easily, i.e ...

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 in OFDM-Based Optical Networks with Elastic Bandwidth Allocation
2010 IEEE Global Telecommunications Conference GLOBECOM 2010, 2010Orthogonal Frequency Division Multiplexing (OFDM) has been recently proposed as a modulation technique for optical networks, due to its good spectral efficiency and impairment tolerance. Optical OFDM is much more flexible compared to traditional WDM systems, enabling elastic bandwidth transmissions.
