CDN node allocation method and apparatus, electronic device, medium and program product

An electronic device, comprising:

• at least one processor configured to execute a computer program stored in at least one memory, wherein the computer program, when executed by the at least one processor, implements following content delivery network (CDN) node allocation operations:
• acquiring a first physical scene corresponding to a first network request;
• determining, in accordance with the first physical scene and a pre-established node quality score table, first quality scores of a plurality of types of CDN nodes corresponding to the first physical scene, wherein the pre-established node quality score table comprises a mapping relation between the first physical scene and the first quality scores of the plurality of types of CDN nodes, the plurality of types of CDN nodes comprise CDN nodes of a plurality of different CDN providers, and a quality score of a single type of CDN node corresponding to the first physical scene is determined based on historical network data acquired by the single type of CDN node under the first physical scene;
• evaluating a quality of the plurality of types of CDN nodes in accordance with the first quality scores of the plurality of types of CDN nodes to obtain a quality evaluation result;
• and
• selecting, in accordance with numbers of nodes respectively corresponding to a plurality of types of candidate CDN nodes in a candidate CDN node set and the quality evaluation result, a CDN node of a first type from the candidate CDN node set, wherein the CDN node of the first type has the highest quality,
• wherein the first network request is a video playback request, and the first physical scene corresponding to the first network request comprises video popularity, a video bitrate, and a startup type of a video on a corresponding CDN node.

A non-transitory computer-readable storage medium having stored thereon a computer program which, when executed by at least one processor, implements following content delivery network (CDN) node allocation operations:

• acquiring a first physical scene corresponding to a first network request;
• determining, in accordance with the first physical scene and a pre-established node quality score table, first quality scores of a plurality of types of CDN nodes corresponding to the first physical scene, wherein the pre-established node quality score table comprises a mapping relation between the first physical scene and the first quality scores of the plurality of types of CDN nodes, the plurality of types of CDN nodes comprise CDN nodes of a plurality of different CDN providers, and a quality score of a single type of CDN node corresponding to the first physical scene is determined based on historical network data acquired by the single type of CDN node under the first physical scene;
• evaluating a quality of the plurality of types of CDN nodes in accordance with the first quality scores of the plurality of types of CDN nodes to obtain a quality evaluation result;
• and
• selecting, in accordance with numbers of nodes respectively corresponding to a plurality of types of candidate CDN nodes in a candidate CDN node set and the quality evaluation result, a CDN node of a first type from the candidate CDN node set, wherein the CDN node of the first type has the highest quality,
• wherein the first network request is a video playback request, and the first physical scene corresponding to the first network request comprises video popularity, a video bitrate, and a startup type of a video on a corresponding CDN node.
