Provided are a method and system for upgrading patching software for a communication device in which software on a forwarding plane is separated from software on a control plane and management plane. The method comprises: a version management process triggers an end of at least one old version process to be upgraded, and keeps data and data states of an upstream process and of a downstream process of the old version process unchanged; when the at least one old version process to be upgraded is successfully ended, the version management process triggers a start of a new version process; and, the upstream process and the downstream process assist the new version process to restore data and data states. The system comprises: a version management component and a data restoration component. The embodiments of the present invention allows for process-level upgrade of software on the control plane and management plane in the communication device, thus preventing unnecessary service interruptions due to software upgrade, increasing service reliability and availability, preventing major economic losses due to service interruption, and enhancing user service experience. |
