Abstract
The present disclosure provides a verifying method and device for consistency of forwarding behaviors of router data based on action codes. The verifying method includes following steps of: determining related functions for a number of functional modules of a router; configuring action codes for the function modules of the router, each functional module sending configured action code to control layer after executing the related function; configuring condition codes for the functional modules of the router; combining parts or all of the functional modules according to a preset combination way; constructing a Trie tree, nodes of the Trie tree storing the action codes of the functional modules; detecting whether there is abnormal forwarding behavior in forwarding process of received data packet according to the Trie tree and the received data packet.
