The present invention discloses an apparatus and method for content caching processing. A controller acquires content caching request information sent by a content server and identifier information of a service node having a content caching function, and constructs traffic forwarding policy information and traffic classification policy information according to the identifier information of the service node having a content caching function; and the controller sends the traffic classification policy information to a traffic classifier, and sends the traffic forwarding policy information to a switch, so as to perform a content caching operation. Therefore, diversified content can be cached to a service node, an Internet content response delay can be reduced, and user experience can be improved.
