Abstract: Embodiments of the present invention disclose a packet processing method and apparatus. A data format of a packet does not need to be understood before the packet is processed, which features high flexibility and commonality and facilitates rapid deployment of a new service. The method includes: acquiring, by a central processing unit CPU, a location parameter of a key and an identifier of a flow table, where the location parameter of the key is used to indicate a location of the key in a packet; acquiring, by the CPU, the key from the packet according to the location parameter of the key; searching, by the CPU according to the key and the identifier of the flow table, the flow table for a flow table entry that matches the key; and processing, by the CPU, the packet according to the flow table entry.
