Content delivery network optimization system

Abstract

A CDN traffic is optimized by a client-side system that maps the servers in the CDN system. Content requests from client devices for domain names are forwarded to servers in the CDN system that may be selected from the map to prevent a cache miss in the a server for a particular request for content.

What is claimed is: 
     
         1 . A method, comprising:
 associating, by a server, one or more edge server network addresses with one or more domain names in a map   performing, by the server, latency measurements by sending measurement probes between the server and edge servers associated with the one or more edge server network addresses;   recording the latency measurements in the map;   calculating a preferred edge server for a particular domain name;   in response to receiving a request associated with the particular domain name from a client device, sending, by the server, a network address of the preferred edge server to an agent component at the client device, wherein the agent component routes all network traffic for a particular application program running on the client device to the server.
