摘要：A method and apparatus for the automatic migration of data via a distributedcomputer network allows a customer to select content files that are to be transferred to
a group of edge servers. Origin sites store all of a customer's available content files. Anedge server maintains a dynamic number of popular files in its memory for the customer.The files are ranked from most popular to least popular and when a file has beenrequested from an edge server a sufficient number of times to become more popularthan the lowest popular stored file, the file is obtained from an origin site. The edgeservers are grouped into two service levels: regional and global. The customer is chargeda higher fee to store its popular files on the global edge servers compared to a regionalset of edge servers because of greater coverage.
