  Research conducted in LTE and 5G wireless communications systems uses common
off-the-shelf hardware components and commercial software defined radio (SDR)
hardware. One of the more popular SDR platforms is the Ettus USRP product line
which uses the UHD driver and transport protocol framework. System performance
can be increased using kernel bypass frameworks along with UHD. This paper
investigates UHD with DPDK in an SDR environment using srslTE as the SDR
application. We present measurement results using the iperf3 network
performance application that show performance improvements when employing a
kernel bypass framework to facilitate data transfer over the network interface
between the SDR application and the radio hardware.
