  • Patent number: 10103980
    Abstract: In some embodiments, a network segment within a switch fabric system includes a layer-2 flood route database and a layer-3 switch interface operatively coupled to the flood route database. The flood route database is configured to store layer-2 flood route information associated with the network segment and contains information such as a set of port identifiers and a set of status indicators. Each port identifier identifies a particular port within the network segment and each status indicator is uniquely associated with a particular port identifier. The layer-3 switch interface associated with the network segment is automatically activated when the flood route database contains at least one valid port identifier and the status indicator associated with at least one port identifier is active. This can allow data traffic to flow between separate network segments within the switch fabric system.

  • Patent number: 10045237
    Abstract: Systems and methods which provide white space channel identification and/or selection using high probability area determinations for a device and availability probability calculations for channels based on a probability model are described. A white space device (WSD) may utilize spectrum scanner sensing results to determine one or more course high probability area (HPA) for the WSD. The sensing results may further be analyzed to derive probability information regarding the WSD being located at the HPAs, to thereby refine the HPAs. Thereafter, the information regarding probabilities of the WSD being located at the HPAs may be utilized with information from a white space location database to determine an availability probability of one or more white space channels. One or more such white space channels may be identified and/or selected for use by the WSD.

  • Patent number: 10007630
    Abstract: A method for transmitting data packets from a first device through a switch to a second device is described. The method is performed at an intercepting device intermediate the first device and the switch device. The method comprises receiving a first data packet from the first device, determining that the first data packet is to be transmitted to the second device and determining whether the first data packet is of a first type that can not be transmitted from the intercepting device to the second device through the switch. If the first data packet is of the first type, the first data packet is encapsulated within a second data packet and transmitting the second data packet through the switch to the second device. If the first data packet is not of the first type, the method comprises transmitting the first data packet through the switch to the second device.
