<p>Embodiments of the present invention disclose a cache collaboration method, apparatus, and system. The method includes: obtaining, by an upper-layer cache node, bandwidth utilization rates of a backbone port and an edge port of the upper-layer cache node respectively, related information which is about each content obtained by a user in a preset time through the backbone port of the upper-layer cache node, and an access count of the user to each content; comparing, by the upper-layer cache node, the bandwidth utilization rate of the backbone port and the bandwidth utilization rate of the edge port; and when a difference between the bandwidth utilization rate of the backbone port and the bandwidth utilization rate of the edge port is greater than a preset value, sending, by the upper-layer cache node, a collaboration request message to a lower-layer cache node to make the lower-layer cache node adjust a collaboration proportion according to the collaboration request message as well as cache space and cached content of the lower-lay cache node. The present invention is applicable to cache collaboration among multiple cache nodes.</p> |
