Abstract: In response to movement of a wireless device, an active tunnel between switches is dynamically included as a member of a virtual network over which the wireless device communicates, where data communicated in the virtual network is carried over the active tunnel, and where the virtual network is overlaid on an underlay physical network that includes the switches and the wireless access points.

Abstract: Examples disclosed herein relate to restoring a flow path in response to a link failure in a software defined network (SDN). In an example, a backup flow path for a flow may be configured in a network device, on a primary flow path of the flow. In response to determination of a link failure in the primary flow path, the network device configured with the backup flow path may be identified. In an example, the network device may be identified by sending, from a detecting network device that detects the link failure on the primary flow path, a message packet successively to each network device preceding the detecting network device on the primary flow path until the network device configured with the backup flow path is identified. The backup flow path may be used to route packets of the flow.

Abstract: Programmed border gateway devices and a corresponding method are provided for stitching together heterogeneous multicast domains within a network. The method includes programming static multicast routes associated with a given multicast flow into border gateway devices. Based on the static multicast routes, the border gateway devices may send join requests to one or more network devices in their domains and receive a multicast stream in response. The border gateway devices may forward the received multicast stream to other border gateway devices, which may deliver the multicast stream to one or more receiving devices in their respective network domains.

Abstract: The present invention relates a system and a method for avoiding congestion in a computer network. Information related to a flow of query data packets in the computer network and a capacity of the computer network is collected for processing. A pattern in the flow of query data packets is determined based on the collected information and a trained data model. The trained data model is used to determine occurrence of an impending connection data burst, in the computer network, which is capable of causing congestion in the computer network. The connection data burst comprises information related to links within routing devices present in the computer network. Upon determining occurrence of the impending connection data burst, parameters configured in the routing devices are modified to avoid the congestion of the computer network by the impending connection data burst.

Abstract: Implementations of the disclosure are directed to using a distributed ledger network to synchronize configuration changes across a network of servers that provide authentication, authorization, and accounting (AAA). In some implementations, a method includes: receiving, at a first server that provides AAA of users that access a network, a user request to update a configuration of a database of the first server, the database including authentication credentials for users that access the network, in response to receiving the user request, transmitting a transaction to the distributed ledger network for validation, the transaction comprising a request by the first server for each server of the distributed ledger network to update their respective database configuration in accordance with the user request; and after the transaction is validated by the distributed ledger network, the first server updating its database configuration in response to receiving the update comprising the validation of the transaction.
