Mattia Cantono, Roberto Gaudino and Vittorio Curri have presented at OFC 2016 the Statistical Network Assessment Process (SNAP). SNAP has been used to compare two different implementations of Flex-Rate Transceivers. In addition to this the concept of Nonlinear Penalty at a network level has been introduced. SNAP has also been used to make a comparison of three different Gaussian Noise based models, showing that the Incoherent GN (IGN) model is both sufficiently reliable and computationally efficient to be used in network related studies.
