The proposed hybrid recovery utilizes flexible optical network with reinforcement learning to recover IP fault for edge network. The testbed experiments indicate, the recovery time is 20% of rerouting-based strategy for a heavy-loaded network.

It demonstrates a flexible optical network enabled “Network Restructuring as Traffic Changes” for 5G/B5G backhaul network, which realizes proactive cross-layer network generation and mitigation-based network recovery, powered by cognitive enhancement and decision deduction.
