摘要:
Systems (360), methods (240), and machine-readable and executable instructions (368) are provided for selecting a server. Server selection can include receiving a first query (114 and 242) at a management server (106) from a local server (104). Server selection can also include triggering a reply race (116, 244) by sending a number of query notifications from the management server (106) to a number of actor servers (108-1, 108-2, and 108-3), wherein each of the number of actor servers (108-1, 108-2, and 108-3), in response to receiving the query notifications (116), sends a response (118) to the local server (104) and wherein a first actor server (108-1) from the number of actor servers (108-1, 108-2, and 108-3) is selected (120) by the local server (104). Server selection can further include resolving, at the management server (116), future queries (246) from the local server by referencing a first report that was received (126) from the first actor server.
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.
