Timing is very critical in ORAN/VRAN implementations. This reminds me my stint when I used to work on Synchronous TDM (SDH and SONET), Digital loop carrier systems dealing with E1/STM/ where synchronization was THE MOST CRITICAL in transport backbone networks. As Things started moving towards packet domain and the synchronization factor became lenient. MPLS based IP transport has lost its relevancy since its not satisfies PTP requirement. 5G rollout into…

My migration failed and as I started log analysis to figure out the issue I found the following error. “ keystoneauth1.exceptions.http.Unauthorized: The password is expired and needs to be changed for user:” On digging further this issue we found that nodes were out…
