Problems solved by technology

Through the existing scheduling method, it is very possible to schedule many access requests for data with low access frequency to IDC nodes with small storage capacity, so that the data stored in such IDC nodes can easily reach the limit of its storage capacity. The upper limit causes the stored data to be updated frequently, increasing the overhead of back-to-source traffic, and the process of back-to-source increases the delay in responding to user requests, affecting user experience

Embodiment Construction

[0036] First, the application environment of a method for scheduling access requests in a CDN network provided by an embodiment of the present invention is described.

[0037]In a CDN network, all IDC nodes can be pre-divided into at least two storage levels according to the storage capacity of each IDC node. For example, if the storage capacity of an IDC node is higher than a certain preset threshold, it will be determined as the first Storage level, if the storage capacity of the IDC node is lower than a certain preset threshold, it will be determined as the second storage level. Of course, the division of the storage level of the IDC node can be carried out by the operator, or by the system according to the IDC The storage capacity is automatically judged.

[0038] IDC nodes of different storage levels are used to respond to access requests for data of different heat levels, and, for any two storage levels A and B, if the storage capacity of the IDC node with storage level ...

Abstract

The embodiment of the invention discloses a method and a device for scheduling an access request in CDN (Content Delivery Network). The method is that all IDC nodes in the CDN are pre-divided into at least two storage levels according to the storage capacity; the IDC nodes at different storage levels are respectively used for responding to the access request of data at different hot levels. The method comprises the steps of receiving the access request of a user to target data; determining the hot level of the target data according to the pre-counted data information at each hot level; further determining a set of the IDC nodes at the storage level corresponding to the hot level; selecting one IDC node to respond to the access request from the determined set. According to the technical scheme, the method has the advantages that the data in the IDC nodes are avoided frequent updating, and the use experience of a user can be increased.

Description

technical field [0001] The invention relates to the technical field of the Internet, in particular to a method and device for scheduling access requests in a CDN network. Background technique [0002] With the rapid development of Internet technology, many large websites tend to use CDN technology to distribute website content. CDN, the full name is Content Distribution Network, that is, content distribution network. The CDN network includes a plurality of IDC (Internet Data Center, Internet Data Center) nodes and scheduling servers, and each IDC node includes a plurality of data cache servers, and the data distributed by the website is stored in the data cache servers. When a user needs to access website data, after scheduling by the scheduling server, he can directly communicate with the IDC node with a lower communication cost to obtain the required data, relieve network congestion, increase the user's website access speed, and improve user experience. [0003] An exis...
