Elastic Optical Networks (EON) emerge as a viable solution to supply the current growing demand for bandwidth. With application of multi-core fibers (MCF) in EON links, it is possible increase availability spectral resources. An network with MCF enables Space-Division Multiplexing (SDM), allowing use more resources and increasing capacity attending circuit requests. However, SDM brings some problems interference between circuits fiber, greater emphasis on crosstalk interference. In this...
This paper evaluates Spatial Division Multiplexing in Elastic Optical Network (SDM-EON) defragmentation scenarios and applies a combined push-pull fast-switching technique that does not disrupt network circuits. A performance analysis is made by means of simulation. The results show the proposed mechanism allows to perform spectrum without circuit interruption, maintaining low blocking rate compromising use resources.

In Elastic Optical Networks (EON), the literature usually measures QoT (Quality of Transmission) by Signal-to-Noise Ratio (OSNR) or estimated maximum transparent reach modulation technique adopted circuit. This paper evaluates Quality Transmission (QoT) margins in traditional Routing, Modulation Level, and Spectrum Assignment (RMLSA) algorithms that quantity through techniques. A RMLSA algorithm is proposed categorizes minimum must be for establishment new circuits, based on their expected...
The energy efficiency in telecommunication networks is gaining more relevance with the actual increasing traffic demand. In this paper, we compare performance terms of and blocking rate elastic optical network (EON) for NSFNET USA topologies, by adopting three modulations formats: Binary Phase-Shift Keying (BPSK), Quadrature (QPSK) Amplitude Modulation (16QAM). An adaptation was made Routing algorithm Level Spectrum Allocation (RMLSA) analysis efficiency. RMLSA adapted chooses route a...
The Sliceable Bandwidth-Variable Transponder (SBVT) enables greater flexibility in elastic optical networks (EON), providing energy efficiency and reducing the resource wastage. Another feature offered by SBVTs is ability to perform grooming. Along with electric grooming a multilevel adaptive modulation, it provides many possibilities dynamic traffic engineering. A key problem how coordinate all these features while promoting good network performance. In this paper, an unprecedented integer...
