The invention relates to a differentiated storage method and device based on a content-centric network. The method comprises the following steps: a current node receives a data packet; a score of the current node for a content corresponding to a content name is obtained by calculation according to the degree number of the current node, the hop number between each node and a user and the type of the content; a caching probability is obtained by calculation according to the sum of the score of the current node for the content and a score of any content of the current node; when the caching probability is greater than a pre-stored probability, the data packet is stored; the data packet is sent to a next node in a path according to path information; and furthermore, when all nodes in the path receive the data packet, the data packet is sent to the user. Differentiated caching strategies can be implemented for different content types; delay sensitiveness requirements of different users are satisfied; and thus, the network storage efficiency is increased.
