The invention provides a traffic protocol identification method and device, electronic equipment and a storage medium, and relates to the technical field of computers, and the method comprises the steps: carrying out the feature matching of non-SP features of load data in to-be-identified traffic; obtaining a first feature ID of each matched non-SP feature; when the first feature ID exists in the rule state machine, determining the first feature ID as a second feature ID corresponding to a child node of the rule state machine; performing node matching based on the second feature ID and an association relationship between a father node and a child node recorded in a rule state machine, and determining whether a target father node exists or not; when a target father node exists in the rule state machine and a target SP feature is mounted under a child node corresponding to the second feature ID, performing SP feature matching on the load data based on feature information of the target SP feature to obtain an SP
