DPDK (Data Plane Development Kit) is an open-source software development kit that provides a set of libraries and drivers for fast packet processing in network devices. It was originally developed by Intel and is now maintained by the Linux Foundation.
DPDK allows network applications to bypass the operating system kernel and communicate directly with the network hardware, resulting in much faster packet processing times. This is achieved through a number of features, including optimized memory management, polling-based input/output operations, and user-level thread management.
DPDK supports a wide range of network interface controllers (NICs), including Intel Ethernet controllers, Mellanox Infiniband adapters, and Cisco NICs, among others. It also provides a number of sample applications and tools for testing and benchmarking network performance.
Overall, DPDK is designed to enable high-performance packet processing, making it well-suited for use in applications such as telecommunications, cloud computing, and content delivery networks.
