Abstract: Techniques and architecture are described for a pull model for obtaining and implementing config changes on network devices are described herein. A user submits intent configuration to the network controller that needs to be delivered to several network sites. The network controller generates a config file. The network controller sends a pull notification message to all network devices that need to retrieve the config file. This pull notification message only contains a corresponding transaction ID for each network device and a location for the network device to use to pull the config file. The network devices may utilize a HTTP REST API exposed by the network controller to obtain the config file from the network controller. The network devices may utilize a REST API exposed by the network controller to reply with statuses of the configuration transaction. The techniques and architecture may be applied to multi-tenant network devices.
