Apparatus and method for performing an online software upgrade of resource servers
First Claim
1. A switch capable of handling call connections between calling devices and called devices, said switch comprising:
- at least one system management node associated with a configuration management controller, said configuration management controller capable of performing an online upgrade of software in said switch by loading upgraded software in a new partition while original software is executed in a reference partition; and
a plurality of computing nodes capable of executing primary-backup resource server applications, each of said primary-backup resource server applications comprising a primary resource server application and a secondary resource server application residing on a different node than said primary resource server application, wherein a plurality of said primary-backup resource server applications form a resource group and wherein an address of said resource group is known in said reference partition and in said new partition.

Abstract
A switch for handling call connections between calling devices and called devices. The switch comprises: 1) at least one system management node associated with a configuration management controller, the configuration management controller for performing an online upgrade of software in the switch by loading upgraded software in a new partition while original software is executed in a reference partition; and 2) a plurality of computing nodes for executing primary-backup resource server applications. Each of the primary-backup resource server applications comprises a primary resource server application and a secondary resource server application residing on a different node than the primary resource server application. A plurality of the primary-backup resource server applications form a resource group and an address of the resource group is known in the reference partition and in the new partition.

8. A method for use in a switch comprising a plurality of computing nodes that execute primary-backup resource server applications, each of the primary-backup resource server applications comprising a primary resource server application and a secondary resource server application residing on a different node than the primary resource server application, wherein a plurality of the primary-backup resource server applications form a resource group and wherein an address of the resource group is known in the reference partition and in the new partition, the method comprising the steps of:
-
loading upgraded software of a first primary-backup resource server application resides in a new partition while original software associated with other primary-backup resource server applications is executed in a reference partition;
partitioning an address space of a service request broker, wherein a first address of a first service request broker associated with the new partition is different than a second address of a second service request broker associated with the reference partition; and
starting the upgraded software of the first primary-backup resource server application in the new partition with the first address of the first service request broker. - View Dependent Claims (9)
