Problems solved by technology

This method is based on whether the neighbor node has cached the data, but if the ICN topology is dynamic and changeable, the fact that the neighbor node has cached the target data at a certain moment does not mean that the neighbor node can still provide the cached co...

Embodiment Construction

[0053] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0054] Embodiments of the present invention provide a method and device for data caching. In this solution, a caching node first judges whether its total space can accommodate the target data to be cached, and then judges whether the remaining space if the item to be replaced can accommodate the target to be cached Finally, judge whether the popularity ranking of the target data to be cached is higher than the ranking of the centrality of the cache node. If the abov...

Abstract

The embodiment of the invention discloses a data caching method and device, applied to a cache node in an information centre network. The method comprises the following steps of: obtaining target to-be-cached data; judging whether the total space can contain the target to-be-cached data or not, if not, forwarding to the next cache node, and if so, determining a to-be-replaced item according to a cache replacement algorithm; judging whether the residual space, after the to-be-replaced item is deleted, can contain the target to-be-cached data or not, and if so, determining the rank of popularities of the target to-be-cached data and the rank of centralities of the cache nodes; and judging whether the rank of the popularities of the target to-be-cached data is higher than the rank of the centralities of the cache nodes or not, if so, deleting the to-be-replaced item, and caching the target to-be-cached data. By means of the embodiment of the invention, the data distribution efficiency can be increased; and more reasonable resource distribution is realized.

Description

technical field [0001] The invention relates to the technical field of network caching, in particular to a data caching method and device. Background technique [0002] At present, research on the background of Information-Centric Network (ICN) is widely carried out. In the information center network, using the network built-in cache to improve data acquisition and transmission efficiency is the most important feature of the network architecture. [0003] In ICN's default caching method, when data is returned to the requester, all caching nodes along the way cache the data, and there is no cooperative caching mechanism. The default caching method forces caching nodes to cache all passing data, not only in the case of limited cache space in the ICN system, but also in the case of limited space, if the caching node caches all passing data, the diversity of data is limited. In addition, it will cause a large amount of data replacement along the way, which reduces the overall ...
