For example, a central node pool and an edge node pool may be maintained, where the service devices included in the central node pool are all central nodes in the CDN network, and the service devices included in the edge node pool are all edge nodes in the CDN network.
In one embodiment, the scheduling device may obtain device information sent by each service device, which may include, but is not limited to, the network node type, operating status, geographic location, load, etc. of the service device.

The central node in the CDN has a distribution function, and can distribute the acquired video stream data to each edge node of the CDN. When the first device is a student client, the student client can access the CDN network. And the student client is used as a media content demander and needs to request to acquire video stream data from the service equipment, and then the student client sends an access request to the scheduling equipment. After receiving an access request sent by a student client, the scheduling device determines a certain service device (edge node) from an edge node pool as a target service device according to first identification information which is carried in the access request and is used for indicating that the student client is a content demander, and sends the access request sent by the student client to the target service device for processing, so that the target service device (edge node) sends video stream data to the student client.
