A method of service content prefetching based on node portrait
Focusing on the service access requirements of edge nodes, aiming at the problems of narrow network bandwidth, poor network quality and low transmission rate of the edge nodes, a node service dynamic demand prediction model based on a forgetting curve is established by mapping the node service demand degree through a node service flow image, and a large-flow service content prefetching strategy is proposed based on the characteristics of the node service flow image, so as to shorten the node user access time to the maximum extent and improve the user access efficiency.
