Abstract
A system and method are disclosed for providing an online software upgrade in a switch in a telecommunications system. The switch includes: 1) a main processing unit for executing call process client applications associated with call connections; 2) call application nodes for executing call process server applications; and 3) system management nodes. A configuration management controller associated with a system management node executes an online software upgrade for the software in the switch while the switch is executing the software that is being upgraded. At least one load sharing policy is capable of associating at least one of the call process client applications with at least one of the call process server applications and to throttle new associations involving the call process server applications.
