The UE may identify a beam failure on one or more active beams used to communicate with the base station, and the UE may transmit a beam recovery message to the base station. In such cases, the beam recovery message may be transmitted according to the configuration received from the base station such that the beam recovery message is transmitted using the beam recovery resources. In some cases, the configuration may be received at the UE via radio resource control (RRC) signaling or via a system information broadcast from the base station.

  • Patent number: 10063474
    Abstract: Systems and methods are disclosed for parallel match processing of network packets to identify data for masking or other actions. In part, the disclosed embodiments receive packets and identify packet data, such as sensitive data, by rapid parallel matching of packet data being communicated in multi-byte wide data paths to match parameters in order to generate match vectors. The match vectors are then used to generate control vectors that are subsequently used by packet processing circuitry to perform desired actions for this packet data (e.g., mask data) and/or for related packets (e.g., drop packets). For example, data identified through the match processing can be masked, and control vectors can be mask control vectors applied to parallel multiplexers. In certain embodiments, the parallel data multiplexers are controlled by the mask control vectors to selectively output either original packet data or mask data that obscures original packet data.

  • Patent number: 10033453
    Abstract: A repeater is implemented as switches, each having ring-connection ports. In an address table in each of the switches, a list of hop numbers is stored as additional information in addition to the addresses, listing hop numbers to each of destination devices for the ring-connection ports in association with an address. When a communication controller in each of the switches finds the same destination address stored in the address table for the ring-connection ports, the communication controller selects, from the address table, one of the two destination addresses for the ring-connection ports having a smaller hop number as a transfer destination of the frame, thereby enabling the frame to take a shortest possible communication route to the destination devices.

  • Patent number: 9929897
    Abstract: The problem of being unable to run microBFD using an IPv6 address over any member links of a layer 2 LAG when the LAG is DOWN (and its IPv6 address becomes or is TENTATIVE), is solved by running DAD for the address configured for the microBFD once the individual link is in DISTRIBUTING or STANDBY state and triggering (or starting) microBFD once the DAD for that address completes successfully. Further, member links of the LAG may be permitted to continue running microBFD even if the LAG interface is DOWN and even if some other member links (but not all member links) of the LAG are DOWN.

  • Patent number: 9921991
    Abstract: Systems and methods described herein facilitate configuration changes to an NIC teaming device while enabling multiple I/O threads continue to run through the NIC teaming device concurrently without interruption. At a given time, multiple configurations of the NIC teaming device, e.g., one for a current configuration of the NIC teaming device and one for a new configuration of the NIC teaming device, can co-exist. For the duration of one iteration, the current configuration of the NIC teaming device used by a specific I/O thread does not change and the new configuration of the NIC teaming device is not adopted by the I/O thread until the start of the next iteration. Once all of the I/O threads finish their current iteration, the configuration of the NIC teaming device is flipped from the current configuration to the new configuration and the current configuration is deleted.
