摘要：
The emergence of flexible frequency grids and distance adaptive modulation transmission methodologies in Elastic Optical Networks (EONs) necessitates novel and efficient Routing and Spectrum Assignment (RSA) and signaling mechanisms to support them. In this paper, we propose an adaptive flag based signaling mechanism for distributed spectrum allocation to maximize lightpath connection establishment by lowering Blocking Probability (BP). Our numerical results indicate significant improvement in the rate of success in establishing dynamically arriving connections. We also proposed an enhanced adaptive approach based on hop count with data driven learning to further reduce the BP in connections.
