Abstract: Embodiments of this disclosure provide a content deployment method and a delivery controller. The content deployment method includes: receiving, by a delivery controller, a content deployment request from an application server controller, where the content deployment request includes identification information of requested content and address information of an application server storing the requested content; and sending, by the delivery controller, a first deployment cache request to a first cache server, where the first deployment cache request includes the identification information of the requested content and the address information of the application server, and the first deployment cache request is used to request the first cache server to obtain the requested content from the application server and cache the requested content. With the content deployment method and the delivery controller in the embodiments of this disclosure, content deployment under control of a content provider can be implemented.

Abstract: This disclosure provides a cache data control method and a device, applied to a first edge cache node. The method includes: receiving a data obtaining request sent from a terminal device, where the data obtaining request includes an identification of to-be-requested data; when the first edge cache node does not include the to-be-requested data, determining a target cache node that includes the to-be-requested data in an edge cache node set corresponding to the first edge cache node and a central cache node corresponding to the first edge cache node; and obtaining the to-be-requested data from the target cache node. This disclosure is intended to improve efficiency of feeding back data information to the terminal device.
