Next-generation 6G mobile communication systems will deliver high data rates and ultra-low latency services through sub-terahertz or terahertz bands. This makes developing wireless access protocols for 6G mobile communication systems a very challenging task. In this paper, we adopt Intel DPDK as a wireless access protocol development platform to implement a wireless access protocol with a processing speed of up to 50Gbps and present its test results. This work demonstrates the feasibility of implementing Tbps-class L2 protocols required for 6G networks using Intel Xeon CPUs and DPDK.
