Apparatus, system, and method for efficiently deploying backup virtual network devices

Abstract:

The disclosed method may include (1) identifying, within a virtual network, a primary virtual network device and a backup virtual network device that is to handle traffic directed to the primary virtual network device following a failure of the primary virtual network device, (2) installing, on the primary virtual network device, a first virtual controller that manages the primary virtual network device, (3) installing, on the backup virtual network device, a second virtual controller that manages the backup virtual network device, (4) directing, by the first virtual controller, the second virtual controller to replicate a state of the primary virtual network device, (5) detecting the failure of the primary virtual network device, and then in response to detecting the failure of the primary virtual network device, (6) directing, by the first virtual controller, the second virtual controller to facilitate handling the traffic directed to the primary virtual network device.
