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.
