Problems solved by technology

[0009] Back-to-origin requests are assigned to each origin server in turn in sequence, and it treats each origin server equally. However, when the origin servers have different capacities, the origin servers with weaker capacities may have high load due to the large number of requests, thus Affects the response to requests assigned to this origin server
On the other hand, the source server with a relatively strong capacity will have idle processing capacity, resulting in a waste of resources, and it cannot be well realized to allocate the corresponding proportion of back-to-source requests according to the capacity of the source server.

Embodiment Construction

[0033] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0034] figure 2 The flowchart of a preferred embodiment of the content distribution network-based method of the present invention is shown. See figure 2 , the implementation steps of the method of this embodiment are described in detail as follows.

[0035] Step S20: Receive the file request from the user that needs to go back to the source, and the edge node of the content distribution network makes the back-to-source request.

[0036] File requests that need to be returned to the source usually include cache expired or not cached or newly released files. When a user requests these cache expired or not cached or newly released files, the CDN edge node makes a back-to-source request.

[0037] Step S21: According to all the source servers and their corresponding proportions, it is determined to allocate to a certain source server.

[0038] It is n...

Abstract

The invention discloses a multi-source load balance method and system for proportional polling based on a content distribution network, which can guarantee normal services of source servers, and realize multi-source load balance on the basis of the normal services of the source servers. According to the technical scheme, the method comprises the following steps of: receiving a file request for source back of a user, wherein an edge node of the content distribution network requires the source back; and configuring the corresponding source servers to implement the source back request according to proportion values of the source servers.

Description

technical field [0001] The invention relates to load balancing technology, in particular to a multi-source load balancing method and system for content distribution network (CDN network) polling. Background technique [0002] The basic idea of ​​the multi-source load balancing technology based on content distribution network polling is: when a client accessing the CDN network has multiple source servers, the edge nodes of the CDN network should distribute the back-to-source requests to each source server in turn, and try to avoid individual The source server can't bear too many requests and affects the service, so as to achieve load balancing among multiple source servers and ensure the normal service of each source server. [0003] The implementation scheme of the current polling multi-source load balancing technology is as follows: figure 1 Shown: [0004] Step S10: When the user requests cache expired or non-cached or newly released files, the CDN edge node returns the ...
