Multi-modal network back-end compiling method and system

The invention discloses a multi-modal network back-end compiling method and a multi-modal network back-end compiling system. The method comprises the following steps: firstly, obtaining an intermediate representation of a multi-modal network program; then, traversing different nodes in the intermediate representation, and extracting key information such as protocol types, protocol fields, tables, actions and the like; then, the extracted information is translated according to a data message processing assembly line of a chip, and a flexible analysis rule and a flexible editing rule of a user-defined field are generated; according to the method and the device, the table entries of the flexible analysis rules of the user-defined fields are merged, and the matching rules of different network modalities are merged into one lookup table, so that the matching entries of multiple modalities are extracted at one time, and the utilization rate of chip resources is improved. 本发明公开了一种多模态网络后端编译方法和系统。本方法包括：首先，获取多模态网络程序的中间
