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.

Abstract: Among other things, embodiments of the present disclosure discussed herein may be used to facilitate the authorization of services between service providers and other users (e.g. customers of the service provider) with accounts on a social network. Unlike conventional authorization systems, embodiments of the present disclosure allow authorizations to occur dynamically at any time, regardless of the physical locations of the service provider and the customer. Embodiments of the present disclosure can also provide service providers and customers information on authorization requests on demand.
