Abstract
Methods and apparatus are provided for selecting a server that can provider content to a client in an optimal manner. A server selection system is coupled to a network node that can identify servers that can provide client reqeusted content. Performance metrics of the servers and their associated priorities are obtained. Servers with metrics that are worse than all the metrics of any other server are optionally eliminated from consideration for best server. Priorities for the metrics are obtained. The metric with the highest priority is applied to analyze the group of servers. The server with the best value for the metric and all servers with metric values falling within a significance window are retained. All others are eliminated from consideration. The other metrics are applied until no metrics remain or only one server remains. If no metrics remain, a best server is identified from the remaining group.
