Impact of transparent network constraints on capacity gain of elastic channel spacing
network constraints channel spacing capacity gain
2015/5/15
We compare fixed-grid network architectures with variable-spacing OFDM based solutions. We show that capacity gains can reach up to 50% but are strongly affected by physical and topological constraint...
Introduction of Confidence Levels for Transparent Network Planning
Introduction Confidence Levels Transparent Network Planning
2015/7/14
Confidence level on connection feasibilities is used to obtain Q-estimate margins when parameter uncertainties are considered. Adding such margins to the Q-estimate instead of fixed margins gives 22% ...
The relevant impact of the physical parameters uncertainties when dimensioning an optical core transparent network
physical parameters dimensioning optical core transparent network
2015/8/3
We illustrate the importance to consider physical uncertainties in the Quality of Transmission estimators used for Impairment Constrained Based Routing. Power uncertainties of 1dB yield 80% of further...
