Abstract: Techniques for automatically claiming switches of a tenant computer network by a remote, cloud-based network controller. A first seed switch is manually claimed by a user by implementing the remote, cloud-based network controller. After claiming the seed switch a set of switches immediately connected with the seed switch are identified by Device Connector logic in the seed switch and immediately connected switches. Switches directly connected to those switches are then identified using Device Connector logic of the switches. This process is performed iteratively by identifying immediately connected switches until all of the switches are identified. All or a subset of the identified switches can then be claimed by the remote, cloud-based controller based on a response from the tenant network user.

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: Techniques for providing a standardized interface that is configured to provide application developers with ways for interacting with different wide area network controllers. A standardized interface may include an application programming interface (API) server that can receive a connectivity request associated with an application that is to be hosted on an application orchestration system. The API server may determine, based at least in part on the connectivity request, a vendor network to be used by the application to send traffic to a remote service. Based at least in part on determining the vendor network, the API server may translate the connectivity request into a first format that is understandable by a controller of the vendor network. The API server may also provide the connectivity request in the first format to the controller of the vendor network such that a path through the vendor network can be determined.

Abstract: Cluster formation for networks for Ultra-Wideband (UWB) Time-Difference-of-Arrival (TDoA) networks may be provided. A plurality of anchors may be set to a primary setting. Synchronization messages may then be broadcast by the plurality of anchors. Then the plurality of anchors may send responses to the synchronization messages. A room consensus may be performed to determine probabilities of obstacles between the plurality of anchors. The plurality of anchors may then send proposals of one or more clusters based on the room consensus. One or more clusters may be formed by the plurality of anchors based on the proposals.

Abstract: Techniques for extended network configuration conversion and reconfiguration are described. A network controller proceeds through a set of extended network nodes in an extended network and reconfigures ports in at the various nodes from a first configuration to a second configuration while preventing network traffic looping and maintaining data and management traffic connection to the nodes during the reconfiguration.

Abstract: In one embodiment, a device obtains a first set of measurements of a path metric for a path in a network that are measured using periodic probing of the path. The device obtains a second set of measurements of the path metric for the path that are measured using fine-grained probing of the path at a higher frequency than that of the periodic probing. The device generates a predictive model that predicts values of the path metric, based on the first set of measurements and on the second set of measurements. The device causes, based on a value of the path metric predicted by the predictive model, traffic to be rerouted from the path to another path in the network.

Abstract: In one embodiment, a device obtains an indication of a network event predicted by a routing engine for a network. The device initiates monitoring of one or more network paths associated with the network event, to determine one or more states of the network. The device makes a comparison between the one or more states of the network and a set of one or more constraints. The device provides a prediction cancelation notification to the routing engine, based on the comparison.
