Embodiment Construction

[0042] The technical solution in this application will be described below with reference to the accompanying drawings.

[0043] First, a brief introduction is made to the relevant concepts involved in the application embodiments.

[0044] Content distribution network is an important part of content distribution. The content distribution network mainly includes data servers and caching servers geographically dispersed in various places. All data is stored on the data server. The cache server provides cache services for the data stored in the data server.

[0045] Wherein, the cache server directly connected to the terminal device is also called an edge server. When a user requests data, it will first initiate a data access request to the edge server. After receiving the data access request, the edge server will check whether it has cached the requested data. If the data requested by the user is cached, it is returned directly to the user. If not cached, the edge server wi...

Abstract

The present application provides a method and device for accessing data, which can reduce the waste of storage resources. The method includes: the first cache server sends a first access request to the second cache server, the first access request is used to request the first data, and the first access request comes from the first edge server; the first cache server receives the response returned by the second cache server The copy of the first data and the first access frequency, the first access frequency is the access frequency of the first edge server to the first data recorded by the second cache server; the first cache server determines whether there is a second access frequency lower than the first access frequency Two access frequency, the second access frequency is the access frequency of the first edge server to the second data recorded by the first cache server, wherein the second data is cached locally on the first cache server; if there is a second access frequency, the first The cache server caches a copy of the first data.

Description

technical field [0001] The present application relates to the field of data caching, and more specifically, to a method and device for accessing data. Background technique [0002] The CDN consists of data servers and geographically dispersed cache servers. Data servers and these cache servers are organized in a hierarchical structure. Wherein, the data server is located at the uppermost layer, and the cache servers are distributed on various layers below the data server. Data is stored on the data server, and the cache server provides a cache service for the data stored in the data server. When a user requests data, an access request is first initiated to a geographically adjacent cache server (called an edge cache server). The edge cache server checks whether the data requested by the user is cached locally. If there is data requested by the user in the cache, it will be returned to the user directly. If not cached, redirect to the upper layer cache server. Until the...
