Upgrading Optical Networks with Elastic Transponders

European Conference and Exhibition on Optical Communication, 2012
We show how rate-adaptive transponders help reduce the cost of optical networks compared to single and mixed-line-rate solutions through a better ability to accommodate growth of traffic and uncertainties in traffic matrices during network upgrades.

Partial defragmentation in elastic optical networks

2014 16th International Conference on Transparent Optical Networks (ICTON), 2014
In elastic optical networks, the lightpaths setup and tear down processes may cause the so-called spectrum fragmentation issue, degrading spectrum utilization, increasing lightpath rejection ratio, and this is especially critical under dynamic traffic scenarios.

Taking Advantage of Elastic Optical Networks

2016
This chapter shows how the new paradigm of Elastic Optical Networks (EON) is changing the way we perceive networking. The mode of operation of EON is described and the potential gains are outlined, followed by Use-Cases outlining how flex-grid technology can be advantageous for multi-layer resiliency, for serving metro networks and finally for data ...

Future Perspectives in Elastic Optical Networks

2018
The new generation Elastic Optical Networks (EONs) based on Orthogonal Frequency Division Multiplexing (OFDM) can accommodate exponentially increasing heterogeneous data traffic efficiently and economically. In EONs, the optimum channel spacing between various subcarriers is very crucial for its efficient performance.
