The external bandwidth is very high, but at the same time, it brings unprecedented challenges to the processor processing capacity of the server. The network processing cannot fully meet the needs of the processor alone, and the network performance problem has even become a bottleneck restricting the further enrichment and improvement of functions.

Embodiment 1
[0027] The present invention provides a method for accelerating network security based on FPGA, such as figure 1 , figure 2 shown, including the following steps:
[0028] S1: The receiving processor writes the quintuple information, corresponding Hash value, and forwarding rules of the first packet by writing into the PCIe BAR register, and converts the quintuple information, corresponding Hash values, and forwarding rules according to the Hash value. The corresponding address is written into the DDR memory, and the forwarding rules include security policies, routing information and processing policies;
[0029] S2: receiving a data packet, buffering the data packet through FIFO and extracting the quintuple information of the data packet;
[0030] S3: Perform a hash operation on the quintuple information of the data packet to obtain the hash value of the quintuple;
[0031] S4: Access the corresponding DDR memory by using the obtained Hash value as the address, read the ha...
Embodiment 2
[0064] An FPGA-based network security accelerator card, such as Figure 5 As shown, including the following parts:

Abstract
The invention belongs to the technical field of data transmission, and particularly relates to an FPGA-based network security acceleration card and an FPGA-based network security acceleration method.The invention provides a novel FPGA-based network security acceleration card and a novel FPGA-based network security acceleration method. According to the FPGA-based network security acceleration cardand the FPGA-based network security acceleration method, a classic quintuple accurate matching flow forwarding mode is adopted to process network messages; and network processingshunting can be carried out on the processor, so that the processor can be liberated from heavy work, and some things which must be done by the processor can be handled, and the data forwarding rate can be further improved.
Description
technical field [0001] The invention belongs to the technical field of data transmission, in particular to an FPGA-based network security acceleration card and an acceleration method. Background technique [0002] With the rapid development of global big data and artificial intelligence technology, the network performance is getting higher and higher, from the original 100M and Gigabitthroughput to the current 10G, 25G, 40G and even 100G, 200G and so on. . The external bandwidth is very high, but at the same time, it brings unprecedented challenges to the processor processing capacity of the server. The network processing cannot fully meet the demand by the processor alone, and the network performance problem has even become a bottleneck restricting the further enrichment and improvement of functions. Contents of the invention [0003] In order to solve the problems in the prior art, the invention provides a new FPGA-based network security acceleration card and an accele...
