Zusammenfassung:Provided are a content service implementation method and apparatus and a content delivery network node. The method includes: sending, to an upper entity, a first download request for requesting to download a first-part fragment of media content; receiving the first-part fragment of the media content sent by the upper entity; receiving, from a lower entity, a second download request for requesting to download the first-part fragment of the media content; and sending the first-part fragment of the media content to the lower entity. In the embodiments of the present invention, before the download request for requesting to download the first-part fragment of the media content is received from the lower entity, the first-part fragment of the media content has been acquired from the upper entity and can be directly returned to the lower entity, so that the response delay of the media content service is reduced. In a video traffic application scenario, the response delay from a user terminal requesting a service to a first video picture is relatively small.
