[0042] Such as figure 1 As shown, the system is mainly composed of two parts, one is the network data processing system itself, and four 10M / 100M / 1000M adaptive interfaces. Among them, eth0 and eth1 are used to forward bidirectional network data; eth2 is used to interact with the background server for system configuration and session flow statistics data; eth3 is a data mirror port, and the system can export specific protocols from the mirror port according to the configuration Or the original data packet of a specific quintuple is sent to the background server for further analysis.
[0043] Such as figure 2As shown, a network data processing system based on a high-performance kernel of improved zero-copy technology, the system can be divided into kernel space and user space on the memory, and the data processing module and the network device driver module are in the kernel space, The data processing module includes a dedicated memory pool (Skbpool) for network data packets...
