OpenNIC and DPDK: Catalysts for Transformation

OpenNIC and DPDK: Catalysts for Transformation

The forefront of network acceleration revolution are OpenNIC and DPDK (Data Plane Development Kit). OpenNIC provides a flexible and programmable environment for deploying custom network functions, while DPDK empowers SmartNIC-Accelerator Card with high-performance packet processing capabilities. Together, they form a dynamic duo, propelling networks into a new era of efficiency and adaptability.
