Abstract

An embodiment of the present invention provides a content distribution method, a content publishing device, a content requesting device, and a routing node, wherein the routing distribution method includes: when receiving a resource acquisition request, adding the name of the resource recorded in the resource acquisition request to Match in the pending interest table maintained by itself; if the name fails to match in the pending interest table, match in the resource cache according to the hash value recorded in the resource acquisition request; if the hash value matches successfully in the resource cache , then return the corresponding resource to the content requesting device; if the hash value fails to match in the resource cache, add a new entry in the pending interest table, and continue to forward the resource acquisition request. The embodiments of the present invention can effectively improve distribution efficiency, shorten network response delay, and increase resource utilization efficiency.

Description

technical field [0001] The present invention relates to the technical field of the Internet, and more specifically, to a content distribution method, a content publishing device, a content requesting device and a routing node. Background technique [0002] With the development of information technology and the characteristics of "interconnection and sharing", the Internet has rapidly expanded its scale, the number of users has grown rapidly, and the amount of content and information has exploded. In view of this, as one of the results of the future network architecture research program, the concept of Named Data Networking (NDN) was proposed. Named Data Networking as a data-centric network architecture. Its distinguishing feature is that it names the content rather than the location of the content, and the communication process is driven by the content consumer rather than the content producer. [0003] During the communication process in the named data network, the conten...
