Abstract

In one aspect of the invention is a method for selecting a site in a network based on the IP (Internet Protocol) of a requesting system. When a request for data is made from a requesting system, the requesting system'"'"'s IP address is used to determine if an edge server, that is, a streaming server co-located with the requesting system'"'"'s Web host, exists for the requesting system. If an edge server for the requesting system exists, then the requesting system receives the requested data from the edge server. If no edge server exists, then the requesting system receives the requested data from a deployment server.

8. The method of claim 7, further comprising if the address does not exist on the database, causing the requested data to be sent from a deployment server to the requesting system, the deployment server being selected based on a non-address based protocol.

9. The method of claim 7, wherein the causing of the requested data to be sent from the selected edge server comprises redirecting the requesting system to the selected edge server.

10. The method of claim 9, wherein the redirecting of the requesting system to the selected edge server comprises sending location information to the requesting system, the location information comprising the address of the selected edge server and the location of the requested data on the selected edge server.

11. The method of claim 7, wherein the predetermined addresses are in CIDR (Classless Inter-Domain Routing) block notation having CIDR blocks corresponding to the plurality of edge servers.

12. A machine-readable medium having stored thereon data representing sets of instructions which, when executed by a machine, cause the machine to:

receive a request for data from a requesting system, the request having an address associated with the requesting system;

receive an identifier corresponding to the address from an edge server of a plurality of edge servers, the edge server having the requested data;

select the edge server to provide the requested data to the requesting system, wherein the selecting of the edge server includes

forwarding the address to a database having a predetermined list of addresses corresponding to the plurality of edge servers, and

looking up the address corresponding to the edge server in the database, wherein the edge server is a nearest streaming server to the requesting system;

return a metafile to the requesting system, wherein the metafile includes a path to the selected edge server; and

direct the requesting system to the edge server to receive the requested data.

13. The machine-readable medium of claim 12, wherein the address comprises an IP (Internet Protocol) address.

28. The machine-readable medium of claim 12, wherein the request comprises a request for media data.

14. An apparatus comprising:

a storage medium; and

a processor coupled to the storage medium, the processor to

receive a request for data from a requesting system, the request having an address associated with the requesting system, receive an identifier corresponding to the address from an edge server of a plurality of edge servers, the edge server having the requested data,

select the edge server to provide the requested data to the requesting system, wherein the selecting of the edge server further includes forwarding the address to a database having a predetermined list of addresses corresponding to the plurality of edge servers, and to look up the address corresponding to the edge server in the database, wherein the edge server is a nearest streaming server to the requesting system,

return a metafile to the requesting system, wherein the metafile includes a path to the selected edge server, and

direct the requesting system to the edge server to receive the requested data.

15. The apparatus of claim 14, wherein the processor is further to look up the address corresponding to the edge server in the database having a predetermined list of CIDR (Classless Inter-Domain Routing) blocks corresponding to the plurality of edge servers, wherein the edge server is the nearest streaming server to the requesting system.

16. The apparatus of claim 14, wherein the address comprises an IP (Internet Protocol) address.

17. An apparatus comprising:

a database having a list of predetermined addresses corresponding to a plurality of edge servers; and

a redirection server coupled to a database, the redirection server to

receive a request for data from a requesting system, the request having an address associated with the requesting system,

lookup the address on the database, and

if the address exists on the database, receive an identifier corresponding to the address from an edge server having the requested data and is nearest streaming server to the requesting system, return a metafile to the requesting system, wherein the metafile includes a path to the selected edge server, and cause the requested data to be sent from the edge server to the requesting system.

18. The apparatus of claim 17, wherein the predetermined addresses are in CIDR (Classless Inter-Domain Routing) block notation having CIDR blocks corresponding to the plurality of edge servers.
