Abstract

The invention discloses a content caching method and a content caching device for a content center network. The method comprises the following steps: determining a shortest path between a content request node and a corresponding content providing node, and determining all the content nodes on the shortest path; determining the node betweenness of the content nodes in turn, and taking the content node with the maximum node betweenness as a center node; and when the storage space of the center node is full, determining the caching probability of effective content nodes in turn, and caching target content according to the caching probability, wherein the effective content nodes are content nodes between the content request node and the center node, and the target content is content requested by the content request node. Through the method, the situation in which target content is cached to all nodes is avoided, and caching redundancy is avoided effectively. Moreover, cache placing nodes are arranged according to the caching probability, the content access speed of the content request node is increased, and the overall performance of the network is improved.

Description

technical field [0001] The present invention relates to the technical field of content-centric networks, in particular to a content caching method and device for content-centric networks. Background technique [0002] Compared with the existing network, the content-centric network is a new type of network architecture. The existing Internet is a host-centered network structure through the TCP / IP protocol. When a network user needs to obtain a certain content, the user needs to access the host server of the content to obtain the content. In a content-centric network, the content name is the center of the entire network. When a user needs to obtain a certain content, the content requester only needs to request the name of the content, and the network obtains it at the nearest node through the content name. content, and then deliver the content to the requester of the content. [0003] In the content-centric network, in-network caching is one of its main technologies. There ...
