This invention discloses a method for reconfigurable modular data plane pipeline assembly and deterministic execution based on XDP. The method includes: generating a Profile configuration file based on the target application scenario, wherein the Profile configuration file describes the module information of the modules to be assembled; obtaining the target information of all modules to be assembled through a loader based on the pre-configured self-describing metadata of the modules, and generating an assembly input list; loading and parsing the Profile configuration file to generate a mapping relationship from stages to module entry points, and writing the mapping relationship into a stage scheduling table; reading the stage scheduling table through the XDP entry scheduler, jumping to the execution entry point of the corresponding module according to the stage scheduling table, and scheduling the execution of the ingress stage chain and the egress stage chain of modules in sequence. This invention abstracts structural changes such as inserting new functional segments, deleting modules, rearranging execution order, and separating ingress and egress processing chains into an assembly problem, thus making it more suitable for building service chains and traffic weaving in physical networks.
