Problems solved by technology

This processing method not only has very low processing efficiency, but also brings a huge operating burden to the CPU. The long-term high-load operation of the CPU will also lead to system instability, and it is also easy to be attacked; once the CPU fails, it will It will directly cause the system to crash and the data will be damaged, so there are problems of unreliability, safety and irrecoverability

Abstract

The invention provides an Ethernet application layer protocol control system based on hardware acceleration. An FPGA performs protocol analysis on application layer network protocol packets, matches the analysis result by utilizing a plurality of parallel protocol identification algorithms, executes a corresponding control operation according to the matching result, discards or forwards the application layer network protocol packets which do not need to be subjected to deep processing, and transmitting the application layer network protocol packets which need to be subjected to deep processingto a CPU for processing; and the FPGA receives and forwards a processing result returned by the CPU to realize protocol control of the application layer. According to the system, a software and hardware combination mode is adopted, the communication connection between the FPGA and the CPU is added, a process of analyzing and processing application layer network protocol packets in a CPU in the prior art is transferred to an FPGA to be realized, the application layer network protocol packets are processed in parallel through the FPGA, and the application layer network protocol packets needingto be processed by the CPU are captured and intercepted and are transmitted back to the CPU for processing, so that the burden of the CPU is greatly reduced, the Ethernet application layer protocol control efficiency is improved, and CPU acceleration is realized.

Description

technical field [0001] The invention belongs to the technical field of computers, and in particular relates to an Ethernet application layer protocol control system and method based on hardware acceleration. Background technique [0002] The data processing performed by the traditional CPU on the received application layer network protocol packets includes protocol packet analysis, control operations, etc. Among them, the analysis of the protocol packet, the control operation and other processing are all operated by the CPU, and the CPU can only process the protocol packet one by one in the way of serial identification and serial control. This processing method not only has very low processing efficiency, but also brings a huge operating burden to the CPU. The long-term high-load operation of the CPU will also lead to system instability, and it is also easy to be attacked; once the CPU fails, it will It directly leads to system crash and data damage, so there are problems o...
