Abstract
Techniques are described for making the best connection between a client and a server. The best connection is determined based upon the proximity of the client to the server, and the load and availability of the server. Proximity is determined by connection racing in which response times to requests made to various sets of servers are compared. The load is determined by back-end monitoring logic for each set of servers and is indicated in the response sent by the server. The availability of the server is monitored by a virtual IP server located with each set of servers. The virtual IP server selects available servers to respond to the request from the client. When the client receives responses, the client selects a server based on (a) the response times and (b) load information in the responses in order to make the best connection.
