  • Publication number: 20060112170
    Abstract: Methods and apparatus are provided for geo-locating load balancing. According to one embodiment, a communication network architecture includes multiple servers, multiple load balancers, and multiple geographically dispersed communication devices. The servers provide services to the communication devices within the communication network. The load balancers each service a shared virtual Internet Protocol (IP) address common to all of the load balancers and perform load balancing of service requests on behalf of two or more of the servers that are located geographically proximate to the load balancer. The communication devices are communicatively coupled with the load balancers and are configured to issue service requests intended for any of the servers to the shared virtual IP address, whereby, upon issuing a service request, a communication device is directed to a particular server selected by a load balancing routine that is associated with a load balancer that is closest to the communication device.
