What is the correct location where the DPDK libraries run?

DPDK (Data Plane Development Kit) is a set of libraries and drivers for fast packet processing. It is designed to run on Intel x86 processors with support for virtualization and non-uniform memory access (NUMA). The correct location where the DPDK libraries run is user space.
User space is the portion of the memory space where user applications and libraries run. In contrast, kernel space is the portion of the memory space where the operating system kernel runs. Network space is not a term used in the context of DPDK.
DPDK provides a set of libraries and drivers that are optimized for user space packet processing. The DPDK libraries bypass the kernel and interact directly with the network interface card (NIC) to achieve high performance packet processing. By running in user space, DPDK avoids the overhead of context switches between kernel space and user space, which can significantly slow down packet processing.
In summary, the correct location where the DPDK libraries run is user space.
