Automatic migration of data via a distributed computer network
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.
1. A method implemented by a service provider on behalf of a content provider, comprising:
organizing a cluster of LAN-connected edge servers into a global cache for caching and serving popular, high-bandwidth content, the cluster organized within a third party edge network close to end users;
the service provider operating a domain name service (DNS) that directs hostname requests to edge servers within the global cache;
locating a service provider server in association with the cluster of LAN-connected edge servers so that content provider content is exchanged between the service provider server and the LAN-connected edge servers without requiring the content provider content to traverse a wide area network (WAN);
filling the global cache with popular, high-bandwidth content from the service provider server, wherein the high-bandwidth content is video content; and
providing the content provider with a report identifying relative popularity of at least two or more videos.
2. The method as described in claim 1 further including tracking popularity of a given video on at least one edge server.
3. The method as described in claim 1 further including collecting data from the edge servers identifying the relative popularity of at least two or more videos.
4. The method as described in claim 1 further including charging the content provider a fee.
5. The method as described in claim 1 wherein the service provider server is in communication with the global cache over a local, dedicated communications channel.
6. The method as described in claim 1 wherein a content provider's most frequently-requested videos are cached and served from the plurality of edge servers in the global cache while the content provider's less frequently-requested videos are stored on the service provider server.
7. The method as described in claim 6 wherein the service provider server is intermediate the global cache and a server associated with the content provider.
8. A method implemented by a service provider on behalf of one or more content providers, comprising:
organizing a cluster of LAN-connected edge servers into a cache for caching and serving popular, high-bandwidth content;
positioning multiple of such clusters within a plurality of third party edge networks to form a global cache, each cluster organized within a third party edge network close to end users that obtain access to the Internet via that third party edge network;
the service provider operating a domain name service (DNS) that directs hostname requests to edge servers within the global cache;
locating a service provider server in association with at least one cluster of LAN-connected edge servers so that content provider content is exchanged between the service provider server and the LAN-connected edge servers in the at least one cluster without requiring the content provider content to traverse a wide area network (WAN); and
selectively filling at least a portion of the global cache with popular, high-bandwidth content from the service provider server, wherein the high-bandwidth content is video content.
