摘要: A scalable system and method for locating a closest server in response to client request via an interactive distribution network, such as the Internet, are provided. content is defined having least round trip time responding request. The including plurality of servers; local communication with clients, acting proxy communicating requests from clients redirection server. Client network distance load information periodically collected at each respective servers. aggregates create clusters both current previously aggregated information. Each cluster represents division or partition total IP address space. then mapped (paired) one more servers network. mapping pairing utilized respond DN received any Another aspect invention involves considering capacities selection probability assigned server/domain index pair prevent repeated lowest thereby overloading that server's service capacity. probabilities effect balancing overloading. collecting without incurring overhead cost by passively TCP it transmitted course normal communications.
