Traditional wavelength division multiplexing networks use fixed grids to meet the needs of today's rapidly evolving networks. The elastic optical network with OFDM as the core can divide the spectrum resources into finer granularity, thereby improving the utilization of network resources and reducing the bandwidth blocking rate in the network. this paper considers risk avoidance to improve the elastic optical network routing and wavelength assignment algorithm based on spectrum coloring theory:doi:10.33969/eecs.v3.013 fatcat:xxwy55ydsbcr5jbmonai4yqzzq
