Patent number: 11855779Abstract: A method for transmitting a message via an access network to a group of terminals is provided. The access network transmits the message to the group of terminals over a broadcast channel. The access network receives a request for retransmission of the message transmitted from a terminal that has not correctly received the message. The access network evaluates a predetermined broadcast retransmission criterion and retransmits the message over a point-to-point link or over a broadcast channel according to the predetermined broadcast retransmission criterion.Type: GrantFiled: April 16, 2020Date of Patent: December 26, 2023Assignee: SIGFOXInventors: Arnaud Mansuy, Juan Carlos Zuniga

Patent number: 11844012Abstract: The present technology is directed to generating a common Border Gateway Protocol (BGP) attribute, for example, BGP-Slice Identifier (ID) for a specific network slice and stitching the network slice across one or more domains to realize end-to-end slicing. The present technology can generate BGP ID for a specific network slice spanning a plurality of domains and map domain-specific attributes associated with sub-slices of the specific network slice in different domains of the plurality of domains to the BGP ID. The present technology can further facilitate distribution of the mapping of the domain-specific attributes to the BGP ID across the plurality of domains for stitching the sub-slices together from the domain-specific attributes based on the BGP ID to stitch the specific network slice across the plurality of domains.Type: GrantFiled: July 2, 2021Date of Patent: December 12, 2023Assignee: Cisco Technology, Inc.Inventors: Rajaneesh Sudhakar Shetty, Ankush Ganpatrai Arora, Atahar Khan

Patent number: 11843600Abstract: An IoT hub comprising one or more servers and databases is configured to automatically assign Internet of Things (IoT) enabled devices to IoT solutions based on a subnet to which the IoT devices are connected. A user interface is configured to enable a user to define subnets within the customer's network environment and assign each subnet to an IoT solution. Upon the user setting up an IoT device's network connection to a network device, such as a router, the IoT device transmits its network information to the IoT hub. The IoT hub can then automatically assign the IoT device to a specific IoT solution without further user input or predict which IoT solution to utilize for that IoT device based on known parameters.Type: GrantFiled: November 5, 2018Date of Patent: December 12, 2023Assignee: Microsoft Technology Licensing, LLCInventors: Nicole Elaine Berdy, Jelani Zukar Brandon, Timothy James Larden, Alexander I.

Patent number: 11824754Abstract: A method is provided that includes receiving, from a first cluster, data intended for a second cluster and routing the data to the second cluster, thereby forming an indirect connection between a first cluster and the second cluster. A network usage of the indirect connection may be monitored and in response to determining that the network usage of the indirect connection exceeds a network usage threshold, a respective remote agent of each of the first and second clusters may be instructed to form a direct connection between the first and second clusters. The network usage of the direct connection may be monitored and in response to determining that the network usage of the direct connection is below the network usage threshold, the respective remote agent of each of the first and second clusters may be instructed to remove the direct connection.Type: GrantFiled: December 3, 2019Date of Patent: November 21, 2023Assignee: Red Hat, Inc.Inventors: Nir Magnezi, Michael Kolesnik

Patent number: 11818142Abstract: An electronic device of a content producer generates a chunk of data, associates a location-independent name with the chunk of data, generates a signature for the chunk of data, attaches the signature to the chunk of data, and transmits the chunk of data, with the signature attached, to one or more user devices in response to respective requests. The signature is generated based on the data in the chunk, using a private key of the electronic device. The electronic device also stores information, including a specification of a public key associated with the private key, in a first ledger entry of a blockchain, to provide the one or more user devices with access to the public key.

Patent number: 11811545Abstract: Some embodiments provide a method for configuring a set of MFEs to implement a distributed multicast logical router and multiple logical switches to process the multicast data messages. The method sends, from a managed forwarding element (MFE) implementing the distributed multicast logical router, a multicast group query to a set of data compute nodes (DCNs) that are logically connected to one of several logical switches and that execute on the same host machine as the managed forwarding element. The method receives multicast group reports from a subset of the set of DCNs and at least one of the multicast group reports specifies a multicast group of interest. The method distributes, to a set of MFEs executing on other host machines, a summarized multicast group report specifying a set of multicast groups of interest to the first MFE (i.e., multicast groups that the first MFE participates in).Type: GrantFiled: December 21, 2020Date of Patent: November 7, 2023Assignee: NICIRA, INC.Inventors: Sami Boutros, Sharath Bhat, Jerome Catrouillet, Subin Cyriac Mathew, Alexander Tessmer
