APPARATUS AND METHOD FOR CONTENT CACHING
First Claim
1. An apparatus for content caching, comprising:
- an acquiring module, configured to acquire content caching request information sent by a content server, and acquire identifier information of a service node having a content caching function according to the content caching request information;
a processing module, configured to construct traffic forwarding policy information and traffic classification policy information according to the identifier information of the service node having a content caching function; and
a sending module, configured to send the traffic classification policy information to a traffic classifier, so that the traffic classifier sends a content packet to a switch according to the traffic classification policy information; and
send the traffic forwarding policy information to the switch, so that after receiving the content packet, the switch sends, according to the traffic forwarding policy information, the content packet to the service node having a content caching function to perform content caching.

Abstract
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.
