Abstract

A system and method are shown for load balancing across global network resources using an existing network protocol, such as Mobile IP, having a redirect feature. According to one method, each of a plurality of servers at a data center uses Mobile IP to obtain an IP address that is also provided to a content server site. Further, a content server site includes a plurality of IP addresses assigned to the plurality of servers and creates a load database including load data for each server. When a client request is received at the content server site from a client device, the content server site determines a network address of a server to process the client request based on the load data, and provides the network address of the server to the client device. When the client device receives the network address of the server, the client device sends an application request to the selected server, and the selected server sends an application response to the client device.
