Problems solved by technology

Most of the existing solutions do not consider the correlation between the user's requests for the same content blocks after the content is divided into blocks, so as to pre-cache the subsequent request blocks of the same content. In addition, when the cache algorithm is designed, each requested content block The popularity is pre-set and cannot reflect the real request of the content block

Embodiment Construction

[0032] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the present invention. Obviously, the described embodiments are the Some embodiments of the invention are not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0033]In the present invention, by analyzing the connection characteristics between the content blocks requested by users in the ICN network, and using the correlation between the content blocks requested by users, a pre-cache strategy for cooperation between nodes is designed. In view of the fact that the existing caching strategy does not fully consider the characte...

Abstract

The present invention provides an ICN network pre-caching method based on the relevance of request content. In the present invention, by analyzing the connection characteristics between user request content blocks in the ICN network, and utilizing the correlation between user request content blocks, a method is designed. A pre-caching strategy that cooperates between nodes. In view of the fact that the existing caching strategy does not fully consider the characteristics of the relationship between the user's multiple requests, this strategy introduces a pre-cache method, which reduces the user's request delay to a certain extent. At the same time, according to the popularity of the requested content, Gradually place popular content on the edge of the network.

Description

technical field [0001] The invention relates to the technical field of information center network, in particular to an ICN network pre-caching method based on request content relevance. Background technique [0002] With the widespread popularization and application of Internet technology, the current network system has many deficiencies, which seriously affect the further development of the Internet. At present, the main body of network applications has changed from hardware sharing to content services of text information, images and videos. It is no longer where the content is stored, but the content itself, as well as the content retrieval and transmission speed, quality and security. Therefore, the host-based communication model is no longer suitable for the needs of current network development. [0003] In recent years, the improved method of separating the content from the host has attracted widespread attention in the academic community. The content-centric network ha...
