Data Plane Development Kit (DPDK) is an open-source software platform that allows developers to build high-performance network applications. It is designed to bypass the operating system and directly access the hardware, which typically leads to significant performance improvements, especially in low-latency and high-throughput scenarios. DPDK is widely used in various industries, from telecommunications to cloud computing, as it offers increased packet processing capabilities and reduced latency.

What is DPDK?

DPDK stands for Data Plane Development Kit and provides a set of libraries and tools that enable developers to write user-space applications that can directly access and manipulate network hardware, such as network interface cards (NICs). It is a framework that optimizes the data path in network applications, allowing for high-performance packet processing.

By bypassing the operating system kernel, DPDK applications can gain direct control over the hardware resources and optimize packet handling. This direct access eliminates the overhead associated with system calls, context switches, and memory copies, resulting in increased performance and reduced latency.
