Hit-Less Dynamic Reallocation for Time-Varying Traffic in Translucent SDM Optical Networks
Paper in proceeding, 2025

In this paper, we address the challenge of resource allocation for time-varying traffic using hit-less reallocation in translucent space-division multiplexing (SDM) elastic optical networks (EON). This algorithm periodically performs hit-less lightpath reallocation aiming to minimize bandwidth blocking probability while assuring uninterrupted traffic provisioning. Lightpaths are reallocated according to specific criteria, such as traffic load in next reallocation period and the number of pairs of nodes to be reconfigured. Simulations on representative network topology with semi-synthetic time-varying traffic validate the effectiveness of our method across different network service types.
