As shown in fig. 1A, in this embodiment, a method for scheduling a CDN is provided, where the method includes:

step 11, acquiring predetermined dimension parameters of different alternative CDNs, wherein the predetermined dimension parameters are at least used for indicating: the performance of the alternative CDN and/or the service price of the alternative CDN are/is selected;

step 12, determining scheduling priorities of different alternative CDNs according to the predetermined dimension parameters;

and step 13, determining a target CDN for the client to dispatch from the different alternative CDNs according to the dispatching priority and the area position of the client.

Here, the scheduling method of the CDN may be performed by a CDN platform.

Here, the client may acquire data from the CDN and provide a content service (e.g., a service in which the content service may be a short video service) to a user. The client may be an application running on a hardware platform. The client may be an application running on the terminal, for example. Here, the terminal may be, but is not limited to, a computer device, a mobile phone, a wearable device, a vehicle-mounted terminal, a Road Side Unit (RSU), a smart home terminal, an industrial sensing device, and/or a medical device, etc.

Here, the CDN is a layer of intelligent virtual network based on the existing internet, which is formed by placing node servers around the network. The CDN can redirect the user's request to the service node nearest to the user in real time according to the network flow, the connection of each node, the load condition, the distance to the user, the response time and other comprehensive information, and the purpose is to select the node relatively nearer to the user to send the content required by the user to the user, thereby relieving the network congestion condition and improving the response speed of the website.

In this way, the target CDN may be determined periodically, so that the CDN scheduled by the client is a preferred CDN.

Here, the predetermined period may be determined according to a quality requirement parameter of a service provided by the client. Illustratively, if the quality requirement parameter of the service provided by the client is greater than the parameter threshold, the predetermined period is greater than the period threshold; or if the quality requirement parameter of the service provided by the client is smaller than the parameter threshold, the preset period is smaller than the period threshold. In this way, the predetermined period can be adapted to the quality requirement of the service provided by the client, and the client can be provided with a preferred CDN in time.

In one embodiment, when the moving speed of the platform where the client is located is greater than or equal to a preset speed, preset dimension parameters of different alternative CDNs are obtained; determining scheduling priorities of different alternative CDNs according to the predetermined dimension parameters; and determining a target CDN for the client to dispatch from the different alternative CDNs according to the dispatching priority and the area position of the client. Therefore, when the mobility of the platform where the client is located is enhanced, the area position where the client is located can be updated in time. Therefore, the target CDN for the client to dispatch can be timely determined from the different alternative CDNs.

Here, the predetermined speed may be determined according to a deployment density of the CDN.

In one embodiment, the ratio of the cost performance is greater than a predetermined value, and the scheduling priority of the alternative CDN is greater than a predetermined priority; or the ratio of the cost performance is smaller than a preset value, and the scheduling priority of the alternative CDN is smaller than the preset priority. Illustratively, the ratio of the cost performance of the first alternative CDN is greater than the first value, and the scheduling priority of the alternative CDN is a first predetermined priority; the ratio of the cost performance of the second alternative CDN is smaller than the first value, and the scheduling priority of the alternative CDN is a second preset priority; wherein the first predetermined priority is higher than the second predetermined priority. As such, the higher the cost performance of the alternative CDN, the higher the priority level of the alternative CDN.

The sensor assembly 614 may include a proximity sensor configured to detect the presence of nearby objects in the absence of any physical contact. The sensor assembly 614 may also include a light sensor, such as a CMOS or CCD image sensor, for use in imaging applications. In some embodiments, the sensor assembly 614 may also include an acceleration sensor, a gyroscopic sensor, a magnetic sensor, a pressure sensor, or a temperature sensor.

The communication component 616 is configured to facilitate communication between the electronic device 600 and other devices, either wired or wireless. The electronic device 600 may access a wireless network based on a communication standard, such as WiFi,2G, or 3G, or a combination thereof. In one exemplary embodiment, the communication component 616 receives broadcast signals or broadcast-related information from an external broadcast management system via a broadcast channel. In one exemplary embodiment, the communication component 616 further includes a Near Field Communication (NFC) module to facilitate short range communications. For example, the NFC module may be implemented based on Radio Frequency Identification (RFID) technology, infrared data association (IrDA) technology, ultra Wideband (UWB) technology, bluetooth (BT) technology, and other technologies.

In an exemplary embodiment, the electronic device 600 may be implemented by one or more Application Specific Integrated Circuits (ASICs), digital Signal Processors (DSPs), digital Signal Processing Devices (DSPDs), programmable Logic Devices (PLDs), field Programmable Gate Arrays (FPGAs), controllers, microcontrollers, microprocessors, or other electronic elements for executing the methods described above.

In an exemplary embodiment, a non-transitory computer-readable storage medium is also provided, such as memory 604, including instructions executable by processor 820 of electronic device 600 to perform the above-described method. For example, the non-transitory computer readable storage medium may be ROM, random Access Memory (RAM), CD-ROM, magnetic tape, floppy disk, optical data storage device, etc.
