An Iterative Optimization Method for Site Selection in Global Load Balance

摘要

Systems, devices, and methods, including executable instructions and/or logic thereon, are provided for server site selection. A system includes a load balancing master configured to have a domain name server (DNS) capability with extensions to support iterative control and a manager capability to select among server sites to probe. The system includes a load balancing slave, communicatively coupled to the master, configured to have a DNS reflection capability to measure a round trip time (RTT) between the load balancing slave and a client local DNS server and an actor capability to respond to commands from the manager and to report a measured RTT to the load balancing master.
