DPDK API (Application Programming Interface) is a set of functions and data structures provided by the DPDK framework for developers to write high-performance networking applications. These APIs offer efficient and low-level access to hardware resources, enabling developers to directly control and optimize network traffic processing.
DPDK API includes several libraries that provide various functionalities such as packet processing, memory management, I/O operations, and communication with other processes. Some of the key libraries in DPDK API are:
The EAL (Environment Abstraction Layer) library provides a platform-independent interface for accessing the underlying system resources such as memory and threads.
The Packet Library provides APIs for packet processing, including packet classification, filtering, and modification.
The Memzone Library offers an API for allocating memory zones, which can be used to share memory between different threads and processes.
The Eventdev Library provides an API for handling events, such as interrupts and timers, that can be used to trigger packet processing tasks.
The Cryptography Library provides an API for cryptographic operations, such as encryption and decryption, which can be used to secure network traffic.
DPDK API also includes tools for debugging and profiling, such as the RTE (Run-Time Environment) Stats Library and L2Fwd sample application, which help developers analyze the performance of their applications and identify bottlenecks.
Overall, DPDK API provides a powerful and flexible framework for developing high-performance networking applications, while maintaining a relatively simple and easy-to-use interface.
