Abstract
Illustrated is a system for performing Deep Packet Inspection (DPI) that includes a core to prepare a data packet for transmission. Further, the system includes a memory controller to direct the data packet to a DPI core. Additionally, the system includes a Network Interface Card to receive the data packet for transmission after DPI is performed on the data packet by the DPI core. The system includes a Direct Memory Management module to update a descriptor that references a received data packet stored in an Operating System buffer. Moreover, the system includes an Input/Output Memory Management Unit to direct the descriptor to be stored in a DPI memory. Additionally, the system includes an interrupt controller to transmit an interrupt to the DPI core to such that the DPI core retrieves the descriptor from the DPI memory and performs DPI on the data packet stored in the OS buffer.
