Abstract
A software reload is executed. The hardware associated with the network device continues to forward network traffic during the software reload. Also, a kernel of the network device operates unaffected in a protected address space throughout the software reload. Further, the kernel preserves local checkpointed and shared memory data. Application processes running on the network node are shut down gracefully. The reloaded software is brought up and the network device is resynchronized.
