Performance Evaluation of Multi-Core Fiber-based Dynamic Spectrally and Spatially Flexible Optical Network with Limited Transceiver Resources

We investigate the blocking performance of a dynamic, spectrally and spatially flexible optical network (SS-FON) in which spectral super-channels(SChs) utilizing multiple modulation formats (MFs) are carried over weakly-coupled multi-core fibers (MCFs) and the amount of transceivers (TRX) in network nodes is limited. In the SS-FON scenario considered, lightpath requests may be blocked not only because of the lack of spectrum resources or due to low transmission quality (QoT), as frequently considered in previous works, but also because of insufficient TRX resources. The main goal of this study is to evaluate the joint impact of these three blocking factors on overall network performance.
