Abstract
The present invention relates to a method for transmitting content in a content-based network and, more particularly, to a content transmission method by which requested content is identified on the basis of a hash value of the requested content so as to be stored only in mapped routers, thereby preventing the same content from being duplicately stored in routers in a regional group such that various types of content can be distributed and stored, and a content request message is directly transmitted only to routers mapped to a hash value of requested content, on the basis of the hash value of the requested content, such that a traffic load, occurring due to the transmission of a content request message by a flooding scheme, can be reduced.
