Abstract
Provided are methods and systems for load balancing client requests between sites associated with a domain name. A method comprises determining a first active response delay time between a local Domain Name System (DNS) server and a first site. The method further comprises determining a first application response delay time between the first site and one or more first servers associated with the first site. According to the method, the first active response delay time and the first application response delay time are compounded to produce a first compounded response delay time. The method further comprises determining a second active response delay time and a second application response delay for a second site to produce a second compounded response delay time. The first compounded response delay time and the second compounded response delay time are compared to perform load balancing between the first site and the second site.
