Problems solved by technology

[0004] It can be seen from the above that in the prior art, when a terminal device needs to obtain data information, it must request data from each cache node and data server step by step, resulting in low efficiency of feeding back data information to the terminal device

Embodiment Construction

[0090] figure 1 The network architecture diagram of cache data control provided by this application. See figure 1 , including a terminal device 101, a plurality of edge cache nodes 102-1 to 102-3, a plurality of central cache nodes 103-1 to 103-2, a data server 104, a cache controller 105 and a link quality collection server 106. The data server 104 stores various data information required by the terminal device 101, and the edge cache node and the central cache node cache part of the data information in the data server 104.

[0091] See figure 1 , multiple edge cache nodes form an edge cache node set, and every two edge cache nodes in the same edge cache node set can communicate directly, for example, a virtual private network (VPN) can be used between every two edge cache nodes Virtual Private Network (VPN for short) mode of communication, usually multiple edge cache nodes located in an adjacent area can form an edge cache node set. Multiple central cache nodes form a ce...

Abstract

The embodiment of the invention provides a caching data control method and device, which are applied to a first edge caching node. The method comprises the following steps: receiving a data acquisition request sent by a terminal device, wherein the data acquisition request includes an identifier of data to be requested; when the data to be requested is not included in the first edge cache node, determining a target cache node including the data to be requested in a set of edge cache nodes corresponding to the first edge cache node and a center cache node corresponding to the first edge cache node; at that target cache node, acquiring data to be request. The caching data control method and device are used for improving the efficiency of feeding back data information to the terminal device.

Description

technical field [0001] Embodiments of the present invention relate to the field of communication technologies, and in particular, to a cache data control method and device. Background technique [0002] A cache node is usually deployed between the data server and the terminal device. The cache node can cache part of the data in the data server. When the terminal device needs to obtain data information from the data server, the terminal device can obtain the required information from the cache node. Data information. [0003] At present, two levels of cache nodes are usually deployed between the data server and the terminal device, which are respectively recorded as the first level cache node and the second level cache node. The terminal device can directly communicate with the first cache node, and the first level cache node can communicate with the second level cache node. Level-1 cache nodes communicate directly, and level-2 cache nodes can communicate directly with data ...
