  • Publication number: 20190149456
    Abstract: Local switching may be provided over a flexible cross-connect VLAN-aware based service. First, a failure of a first segment link of a first segment may be detected by a first network device. The first segment may have a first segment identifier and the first segment link may be connected to the first network device. Next, a route withdraw indicating the first segment identifier may be sent by the first network device in response to detecting the failure of the first segment link of the first segment. A second network device may then receive the route withdraw. Then, the second network device may forward, in response to receiving the route withdraw, traffic received from the first network device to a second segment link of the first segment connected to the second network device. The traffic may be received from the first network device over a backup connection over an Ethernet Virtual Private Network (EVPN) core.

  • Patent number: 10291494
    Abstract: A method provided in a network including edge devices to collect data from data producers connected to the edge devices and to communicate with cloud-based prosumers connected with the edge devices. Data analytics tasks are identified. The data analytics tasks are used to process data collected from a data producer among the data producers to produce a result for consumption by one or more of the cloud-based prosumers. For each data analytics task it is determined whether a computational complexity of the data analytics task is less than or equal to a predetermined computational complexity. Each data analytics task determined to have a computational complexity less than or equal to the predetermined computational complexity is assigned to an edge device among the edge devices. Each data analytics task determined to have a computational complexity that exceeds the predetermined computational complexity is assigned to a prosumer among the prosumers.

  • Patent number: 10291762
    Abstract: A method for joining a mobile device to a meeting event begins with docking a mobile device in a docking station. The mobile device can be associated with a user profile, and is operable to receive a monitoring input. The mobile device detects a change in the monitoring input, and determines whether or not the change in the monitoring input corresponds with a docked state of the mobile device. Upon determining that the change in monitoring input did correspond with a docked state, a meeting application of the mobile device configures a docking mode of the mobile device. The meeting application connects to a meeting calendar that is associated with the user profile, and retrieves a desired meeting event from the meeting calendar. The meeting application then joins the desired meeting event.

  • Patent number: 10291512
    Abstract: In one embodiment, path routing in a node fabric of an information-centric network (ICN) includes transmitting a request from a source application to an upstream node via node faces of nodes in the node fabric along a path encoded in a Path Steering Value (PSV); and receiving at the source application from the upstream node a reply that travels along a return path encoded in the PSV. The PSV is generated by pairwise encoding pairs of node faces successively traversed by the reply and is represented by a deterministically decodable pairing function. Node face identifiers can be deterministically, i.e., uniquely, decoded from the PSV. The deterministically decodable pairing function is selected from a Cantor function, a Hopcroft and Ullman variant of the Cantor function, Hilbert curve algorithm, Morton code, and a bitwise pairing function.
