Today’s networks have limitations that increase operational cost, slow new wavelength activation times, limit reach, and prevent the network from operating at its highest possible capacity. These limitations include planning tools that lack real-time data from the optical network and therefore must stack margin to accommodate worst case scenarios, coherent receivers that are not able to measure OSNR or residual margin, and NMS, SDN, and ASON/ GMPLS implementations that lack the sophisticated optical performance models of offline planning tools. As the network becomes more dynamic with the adoption of SDN and the evolution of flexi-rate interfaces with a wider range of modulation schemes and baud rates, these limitations will impose an increasing cost. This white paper explains how Coriant technology can evolve the awareness of optical networks to address today’s limitations and enable more dynamic networks that are able to fully leverage next-generation coherent technology.
WHAT IS AWARENESS?
The Cambridge English dictionary defines awareness as “knowledge that something exists, or understanding of a situation or subject at the present time based on information or experience.” As far as optical networks are concerned, awareness can have two meanings. In line with the first part of this definition, a planning tool that is able to model nonlinear effects could be said to be aware of them. Alternatively, in line with the second part of this definition, awareness could mean that the network is able to measure the actual, real-time impact of these nonlinear effects.
