. This figure describes the communication between software, firmware, and hardware, where DPDK applications use the rte_flow API to offload packet processing to hardware. The VTL Driver converts API parameters into hardware configuration data, which is transmitted via the Axi-Stream bus. The Rule Parse block analyzes flow rules and directs them to the appropriate handler (Wildcard or Exact Match). The hardware configuration is then sent to the NIC card through the PCIe interface, with the VFIO-PCI Driver bypassing the Linux kernel space. For wildcard flows in min-max form, I developed an algorithm to break down min-max flows into individual flows and configure them into the table. Next slide, I will present this algorithm.
