Abstract :
Site selection method determines the best server for a given client among multiple replicated servers deployed at geographically distributed locations. It is an important function of a global load balancing (GLB) system in application delivery controller (ADC) which is usually deployed at the entry of data centers. This paper presents a site selection method based on DNS Reply Race and Reflection (DR3), which achieves higher selection accuracy and incurs less system cost compared with conventional methods as Geo-mapping, Ping and DNS reply race.
