AI Technical Summary

Problems solved by technology

When the load of the parent cluster is high at the same time, additional bandwidth billing of the parent cluster may be added, that is, the cost of returning the edge cluster to the parent is higher; because the file distribution system cannot send The corresponding customer charges can only be used as the operating cost of the file distribution system
In this way, the operating cost of the file distribution system becomes higher

Embodiment Construction

[0019] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0020] This application provides a file access scheduling method, which can be applied to such as figure 2 In the central server of the system shown. The execution of the method is participated by the central server, the edge cluster and the parent cluster. Among them, the edge cluster is composed of cache servers, which are used to directly respond to the user's file access request and cache the files required by the user. The parent cluster is also composed of cache servers, which are used to obtain files from the source server and cache files required by users. The central server is associated with the edge cluster and the parent cluster, and the edge cluster and the parent cluster report file pool information, performance indica...

Abstract

The invention discloses a file access scheduling method and a central server. The method comprises the steps: receiving a file access scheduling request sent by an edge cluster, and searching for a first target cluster set of target files requested by the file access scheduling request, wherein the first target cluster set is a set of the edge cluster and a parent cluster in which the target filesare cached; if the first target cluster set is not empty, determining a second target cluster set meeting quality requirements in the first target cluster set; searching a cluster meeting a cost requirement in a second target cluster set, and determining a search result as a target cluster, so the edge cluster acquires the target file from the target cluster. According to the technical scheme, the target cluster meeting the quality requirement is determined according to the lowest cost principle, and the cost for the edge cluster to access the target cluster to obtain the target file is reduced.

Description

technical field [0001] The invention relates to the technical field of the Internet, in particular to a file access scheduling method and a central server. Background technique [0002] With the rapid development of the mobile Internet, Content Delivery Network (CDN) has been widely used in live streaming, website acceleration, Various usage scenarios such as game video acceleration. [0003] figure 1 A schematic diagram of an existing CDN-based file distribution system architecture is shown, including edge clusters and parent clusters. The cluster refers to the collection of multiple servers for the same type of service, which is equivalent to one server for users. [0004] In the past, when users needed to obtain files, they first sent a file acquisition request to the edge cluster of the file distribution system; The edge cluster directly obtains the corresponding files from the planned parent cluster and sends them to the user without considering the cost of returnin...
