code push

The act of sending code to a limited number of seed NICs. Pushing the image to a few seed NIC (about 3%) and instructing the non-seeds to acquire the image from their direct neighbors is much more resource-efficient than pushing the image to all NICs. This way, network traffic associated with a firmware upgrade takes place between direct neighbors and not along mission-critical routes between the data center and endpoints. Disruption of normal network traffic, such as metering schedules and events, is reduced as much as possible.
