In Linux systems, the network protocol stack is implemented in the kernel of the operating system, but is just an application, not a system category, and the data processing and the logic control are not separated, so that the management is confusing. All applications related to network processing require the participation of the network protocol stack of the kernel, and consume a great deal of CPU computing resources.
The well-known DPDK is to directly pull the data packet to the user mode for processing, and although the method bypasses the kernel of the operating system, because the network card has limited functions, no logic calculation unit is provided, only IO operation for receiving and transmitting the data packet and a very small amount of data packet cache are required, and most of protocol flows are required to be completed by a host CPU. Even though the technical implementation of DPDK bypasses the operating system kernel, the use of CPU computations is still necessary, so the use scenario of DPDK is generally to allocate one or several CPU cores specifically to process the data packet.
