Multi-vendor OpenROADM Testbed Supporting the Live-Migration of a 5G gNB-CU-UP Container
This paper presents a proactive live migration of the gNodeB Central Unit User Plane (gNB-CU-UP) container in a 5G virtualized Radio Access Network (vRAN) testbed across a multi-vendor OpenROADM optical transport network (OTN). An automated mechanism monitors the CPU usage and dynamically reconfigures midhaul and backhaul wavelength services to maintain low-latency transport. Leveraging Pacemaker and Corosync for seamless Virtual IP (VIP) handover, the proposed mechanism achieves a UE Service Recovery Time of 1.04 sec ensuring minimal disruption.
