Abstract
Disclosed is a computer-implemented method of rebalancing persistent client connections to a cluster of servers. The method comprises identifying an increase in a total client connection capacity of the cluster of servers with a network connection balancing component; and for each server in a selection of servers in the cluster of servers calculating a current client connection capacity utilization of the server from the number of persistent connections to the server and the current capacity of the server; comparing the current client connection capacity utilization with the target client connection capacity utilization; and terminating a selection of its persistent client connections by a server based on its current client connection capacity utilization exceeding the target client connection capacity utilization. Also disclosed are a computer program product and a computer system for utilizing the computer-implemented method.

10. A computer program product comprising a computer readable storage medium having computer readable program instructions embodied therewith for, when executed on a computer system implementing a cluster of servers and comprising a processor arrangement adapted to execute the computer readable program instructions, cause the processor arrangement to:
-
identify an increase in a total client connection capacity of the cluster of servers; determine a target client connection capacity utilization from the increased total client connection capacity of the cluster of servers and the number of persistent connections to the cluster of servers; and for each server in a selection of servers in the cluster of servers; determine a current client connection capacity utilization of the server from the number of persistent connections to the server and a current capacity of the server; compare the current client connection capacity utilization with the target client connection capacity utilization; and terminate a selection of its persistent client connections based on its current client connection capacity utilization exceeding the target client connection capacity utilization. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17)

18. A computer system comprising a cluster of servers listening to a shared IP endpoint and a network balancing component for balancing client connections to a server in the cluster of servers,
the network balancing component being adapted to: -
identify an increase in a total client connection capacity of the cluster of servers; and determine a target client connection capacity utilization from the increased total client connection capacity of the cluster of servers and the number of persistent connections to the cluster of servers; the computer system further being adapted to, for each server in a selection of servers in the cluster of servers; determine its current client connection capacity utilization from its number of persistent connections and its current capacity; and compare its current client connection capacity utilization with the target client connection capacity utilization; and each server being adapted to terminate a selection of its persistent client connections based on its current client connection capacity utilization exceeding the target client connection capacity utilization. - View Dependent Claims (19, 20)
compare its current client connection capacity utilization with the target client connection capacity utilization; and communicate a persistent connection termination message to each server in the cluster of servers having the current client connection capacity utilization exceeding the target client connection capacity utilization; each server receiving the persistent connection termination message being adapted to terminate the selection of its persistent client connections in accordance with the received persistent connection termination message.

20. A computer system according to claim 18, the network balancing component being further adapted to:
-
communicate the determined target client connection capacity utilization based on the increased total client connection capacity to the selection of servers in the cluster of servers; and each server being further adapted to determine its current client connection capacity utilization from its number of persistent connections and its current capacity and compare the communicated determined current client connection capacity utilization with the target client connection capacity utilization.
