Protocol analysis method and system of programmable network and readable storage medium

Abstract

The invention discloses a protocol analysis method and system of a programmable network and a readable storage medium. The protocol analysis method mainly comprises two parts: a front end side converts a user-defined protocol written by a user based on a P4 language into information in a json format; and the back end side extracts the information required for converting the information into the UDFSAI from the information in the json format and the flow table information configured by the user, operates the ASIC switch through the UDFSAI, and finally realizes the analysis of the user-defined network protocol on the ASIC switch. According to the invention, the traditional ASIC switch supporting UDFSAI can also analyze the custom protocol through the P4 language, so that the development time of the custom protocol is saved, and the application range of the traditional ASIC switch is widened.

Description

technical field [0001] The invention belongs to the technical field of protocol parsing and processing, and in particular relates to a protocol parsing method, system and readable storage medium of a programmable network. Background technique [0002] As the scale of the Internet continues to expand, the update speed of network protocols continues to accelerate, which requires network devices to quickly adapt to new network protocols, while current network devices generally use traditional Application Specific Integrated Circuits (ASICs). ) implementation, but ASIC usually only supports inherent protocols, and cannot support flexible custom parsing of network protocols, so when new protocols are encountered, the usual practice is to gradually arrange the chip manufacturers according to the actual situation after the relevant protocol specifications are proposed. The new chip version is supported, but due to the inherent R&D cycle and R&D costs of the chip, it will take about...

Problems solved by technology

[0002] As the scale of the Internet continues to expand, the update speed of network protocols continues to accelerate, which requires network devices to quickly adapt to new network protocols. Current network devices generally use traditional Application Specific Integrated Circuits (ASIC) ) implementation, but ASIC usually only supports inherent protocols, and cannot support flexible custom analysis of network protocols. Therefore, when encountering new protocols, the usual practice is to gradually arrange them according to the actual situation after the relevant protocol specifications are proposed. Launch support for new chip versions, but due to the inherent R&D cycle and R&D costs of chips, it takes about 3 to 5 years for ASIC to support new network protocols, which cannot meet the time requirements of users for new network protocols , and because traditional network equipment usually implements support for new network protocols by replacing new chips, which requires extremely high equipment investment costs
