Abstract
The present invention provides a computer system having a control process and a device driver process that is in communication with the control process, and a local back-up process, independent of both the control process and the device driver process. The local back-up process facilitates recovery of the device driver process. In one aspect of the invention, the computer system is a network device that includes a control plane and a data plan. The control plane includes a control process, and the data plane includes a device driver process. A local back-up process, independent of both the control process and the device driver process, facilitates recovery of the device driver process if the device driver process is terminated.
