Abstract
The invention provides a system and method for updating software in the CPU of a network device without interrupting the operation of the network device. The invention determines whether operating state information is recoverable. If it is not recoverable, then it will be stored in a metadata module or reload buffer. When the CPU is rebooted, after a software update or crash, it operates in a special reload mode and is able to recover any system state information not available in the network device from the metadata module.
