A Fast and Low Capacity Virtual RAN Recovery based on PDCP Split and Optical Fronthaul Traffic Filtering
This paper proposes a Packet Data Convergence Protocol (PDCP) traffic filtering with virtual distributed unit (vDU) and central unit (vCU) hot-backup to reduce the fronthaul connection recovery time during the virtualized function failure. This architecture permits to maintain the communication between the Evolved Packet Core (EPC) and the User Equipment (UE). Experimental results show that a service recovery time is able to achieve in three seconds.
