ABSTRACT:
A method for performing an in-service software upgrade to a data router follows steps of (a) providing a source node hosting an upgrade software package; (b) causing an upgrade command to be executed; (c) establishing, as a result of the upgrade command, a network session between the data router and the source node; (d) receiving the upgrade software at the router; (e) copying and distributing, within the router, the upgrade software to designated components slated for upgrade; (f) designating one or more components in the router as backups for each component to be upgraded; (g) backing up services and software running on each target element to be upgraded to designated backup element or elements while upgrade proceeds for the target element; (h) causing a switchover at the target element to the new software; and (i) repeating steps (g) and (h) until all the components slated for upgrade are upgraded.
