Abstract: A method and an apparatus for compressing a content name are provided. In the method, a controller constructs a content name tree according to content names in a content database, where a first node of the content name tree stores a first-level prefix of a content name in the content database, and an Nth-level node of the content name tree stores prefixes of first N levels of the content name; and then the controller compresses a content name stored in the Mth-level node into a first content name stored in a father node of the Mth-level node when determining that the content name stored in each Mth-level node in the content name tree is corresponding to a first network node in a network. Thus, compression of a content name in a content name database is achieved, and space occupied by the content name is saved.

Abstract: Embodiments of the present invention provide a method for routing and forwarding. The method includes: receiving, by a network controller, a routing request message sent by a requesting routing node, where the routing request message carries a content name of requested content; determining, by the network controller according to a network topology diagram and registration information of the requested content, a proper forwarding path; and delivering, by the network controller, routing information to each routing node on the forwarding path. In the embodiments of the present invention, a network controller is introduced, and registration information and a network topology diagram are stored in the network controller, so that the network controller may be used to determine a forwarding path of a content request packet, which reduces blindness of routing and forwarding of the content request packet in an ICN network and improves efficiency of routing and forwarding.
