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 ...

Routing and Scheduled Spectrum Allocation for transfer-based datacenter connections
2015 17th International Conference on Transparent Optical Networks (ICTON), 2015Creating datacenter (DC) federations allows DC operators to reduce costs and increase their revenues from using under-utilized resources as well as to expand their geographical coverage aiming to improve users' Quality of Experience. Since huge capacity is needed to interconnect the DCs in a federation, elastic optical networks can be used.

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.

Protection, Routing, Spectrum and Core Allocation in EONs-SDM for Efficient Spectrum Utilization
ICC 2019 - 2019 IEEE International Conference on Communications (ICC), 2019The use of protection in elastic optical networks (EONs) with spatial division multiplexing (SDM) can lead to under-utilization of the spectrum, since a high number of resources is reserved for protection. In this paper, we propose an algorithm that employs minimum interference routing, FIPP p-cycle, optical traffic grooming, and spectrum overlap to ...
