Implemented a prototype of gNB-CU-UP a network element of 5G Radio Network. Using DPDK, a set of data-plane processing libraries and NIC drivers for high speed packet processing applications. Includes a Platform Software (which can be reused across gNB-CU-UP, gNB-DU and UPF) and GTP-U, PDCP and SDAP protocol stack which implemented as per 3GPP specifications.

PFM

PFM is a prototype of gNB-CU-UP a network element in teh 5G Radio Access Network. It make use of DPDK for User-Plane Packet Processing and Includes a Platform software that can be used as a framework to build other network elements on, the platform software handles important features like ARP, Routing tables and multi-thread support.

PFM Features

• ARP support for DPDK interfaces.
• KNI Integration.
• Routing tables using Longest Prefix match.
• Multi thread support using rte_distributor.
• Communication between threads using rte_ring structures.
• GPRS Tunneling Protocol implementation.
• CLI interface to access ARP and Routing tables.
