Abstract

Abstract:

In order to set up an algorithm suitable for data distribution network of extensible messaging and presence protocol (XMPP) server cluster system with a relatively large number of sessions and the number of sessions, the weighted least connections algorithm was improved. This algorithm dynamically acquires the server's occupancy resources, and calculates the current load capacity and load level in real time. The servers' loading status is divided into three stages by the threshold values, and the servers are scheduled with two different algorithms. The algorithm can effectively improve the load performance of the server cluster.

Key words: extensible messaging and presence protocol (XMPP) server, load cluster, least-connections algorithm
