Elastic Bandwidth Allocation in Flexible OFDM-Based Optical Networks
TL;DR: This work introduces the Routing, Modulation Level and Spectrum Allocation (RMLSA) problem, as opposed to the typical Routing and Wavelength Assignment (RWA) problem of traditional WDM networks, proves that it is also NP-complete and presents various algorithms to solve it.
Journal ArticleDOI
A Survey on Optical Interconnects for Data Centers
TL;DR: A thorough survey on optical interconnects for next generation data center networks is presented and a qualitative categorization and comparison of the proposed schemes based on their main features such as connectivity and scalability are provided.

Siamak Azodolmolky,Miroslaw Klinkowski,Eva Marin,Davide Careglio,Josep Solé Pareta,Ioannis Tomkos +5 more
TL;DR: This work compiles a comprehensive survey of the proposed algorithms that address the physical layer impairments in the routing and wavelength assignment (RWA) problem in transparent optical networks.
Proceedings ArticleDOI
Routing and Spectrum Allocation in OFDM-Based Optical Networks with Elastic Bandwidth Allocation
TL;DR: This work considers the planning problem of an OFDM-based optical network where connections are given a traffic matrix that includes the requested transmission rates of the connections to be served, and proposes a heuristic algorithm that serves connections one-by-one and uses it to solve the Planning problem by sequentially serving all traffic matrix connections.
