ABSTRACT:
A method and apparatus for the automatic migration of data via a distributed computer 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. An edge 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 been requested from an edge server a sufficient number of times to become more popular than the lowest popular stored file, the file is obtained from an origin site. The edge servers are grouped into two service levels: regional and global. The customer is charged a higher fee to store its popular files on the global edge servers compared to a regional set of edge servers because of greater coverage.
