A Web server selection algorithm using QoS measurement

We compared several server algorithms and found that performance of server selection can be improved using QoS statistics (average of past weeks QoS values) and real time QoS probing. Specifically, a set of candidate servers are selected based on QoS statistics for a given time section of the day and day of the week. A target server is, then, selected among the pre-selected candidate servers based on real time QoS measurement using echoping.
