Embodiment Construction

[0055]The technical solutions in the embodiments of the present application will be described below with reference to the accompanying drawings.

[0056] Figure 1A It is a schematic diagram of an application scenario provided by the embodiment of this application. This application scenario involves scheduling CDN edge nodes. The execution subject includes: a terminal device 101 installed with a video APP, a dispatch proxy server 102 , a target CDN dispatch center 103 and a target CDN edge node 104 . It should be noted that, in this embodiment of the application, there may be multiple CDNs providing video playback services, and each CDN corresponds to a CDN scheduling center, and the CDN scheduling center is responsible for scheduling multiple CDN edge nodes included in the CDN. In this application scenario, it is assumed that each CDN scheduling center supports proxy scheduling, such as cloud-side proxy scheduling. Usually, to schedule a CDN edge node, it is first necessary...

Abstract

Embodiments of the present application provide a method and device for scheduling CDN edge nodes in a content distribution network. The method includes: the scheduling proxy server receives a first request message from the terminal device, the first request message includes a first IP address, and the IP address is the IP address of the terminal device; according to the first IP address and configuration information, determine the The target CDN scheduling center of the IP address; when the target CDN scheduling center supports setting proxy scheduling, send a second request message to it, the second request message includes the first IP address, and is used for the target CDN scheduling center to determine according to the first IP address The second IP address, the IP address is the IP address of the target CDN edge node corresponding to the first IP address; receiving the second IP address sent by the target CDN dispatching center; sending a request response message to the terminal device, and carrying the second IP address in the request response message The second IP address is used for the terminal device to acquire and distribute content from the target CDN edge node according to the second IP address, which can improve the success rate of content acquisition.

Description

technical field [0001] The present application relates to the communication field, and in particular to a method and device for scheduling edge nodes of a content delivery network (content delivery network, CDN). Background technique [0002] Video service operators use CDN to provide users with services such as video-on-demand or live broadcast, and often use the service capabilities of multiple CDN manufacturers. [0003] For the user's video playback request, the global server load balance (GSLB) scheduling system of the CDN uses a scheduling method, generally according to the principle of the nearest scheduling, to schedule the request to the CDN edge node closest to the user, and the CDN edge node Nodes provide services to users. The existing system uses the end-side application program (application, APP) to directly initiate a request to the GSLB dispatching system of the CDN. Scheduling to the CDN edge node serving this region. [0004] The GSLB scheduling system i...
