TL;DR: GNPy is validated by feeding it with data from the network controller and comparing the results to experimental measurements on mixed-fiber, Raman-amplified, multivendor scenarios over the full C-band, showing excellent accuracy in predicting both the optical signal-to-noise ratio and the generalized signal- to-no noise ratio (GSNR).

TL;DR: This work presents an exhaustive analysis and an accurate evaluation for spectrum fragmentation issue in flexible optical networks and proposes new metric for fragmentation measurements and some approaches to address such a problem.

TL;DR: It is shown that, over the equipment's lifetime, for IP/MPLS routers it is reasonable to almost double the optimal power rating value under real-life equipment filling conditions, and power measurements on IP routers and Optical Line Amplifiers show that their power consumption marginally depends on traffic load.

TL;DR: A practical implementation of sleep mode strategies for network operators is to define, on the basis of typical traffic trend, few configurations to be activated in specific time instants.

TL;DR: This work looks at the electrical and optical layers of IP-over-WDM networks, and presents a list of evaluation criteria for energy- aware adaptive routing solutions (EA-ARSs) from the perspective of a network operator.
