RT Conference Proceedings T1 Experimental Demonstration of a Packet-based Protection for Seamlessly Recovering a Multi-layer Metro Network Fronthaul Failure A1 Kondepu, K. A1 Ramanathan, S. A1 Tacca, M. A1 Razo, M. A1 Mirkhanzadeh, B. A1 Giannone, F. A1 Valcarenghi, L. A1 Fumagalli, A. AB Packet loss in the fronthaul adversely affects radio services, especially the low-layer functional split options between Distributed Unit (DU) and Central Unit (CU). A 1+1 protection scheme is implemented in a Software Defined Networking (SDN) packet-over-optical transport test-bed, achieving seamless recov-ery of the 7-1 split option from an optical link failure in the fronthaul.
