  • Patent number: 10194442
    Abstract: Methods, systems, and devices for wireless communication are described. Uplink resources may be allocated for transmissions of beam recovery messages. For example, a user equipment (UE) communicating in a system that supports beamformed transmissions may receive a configuration for resources from a base station, where the resources may be used for beam recovery signaling. 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: 9600245
    Abstract: A computer-implemented method for generating control unit program code. The control unit program code or an intermediate representation in the generation of the control unit program code is generated from at least one first data object with at least one first software tool. The first software tool outputs at least one message about the generation process during the generation of the control unit program code or the intermediate representation, and a computer-implemented message management environment acquires the message output by the software tool. The evaluation of the messages output by the software tools during the generation process is achieved in a more effective manner in that a qualification for the acquired message at least as open or approved is acquired by the message management environment and in that a qualification precondition for a message qualified as approved is also acquired by the message management environment.

  • Patent number: 9432385
    Abstract: A method to mitigate attack by an upstream service provider using cloud mitigation services. An edge detection device, which located at the subscriber's network edge, is able to communicate information via status messages about attacks to an upstream service provider. The service provider is then able to mitigate attacks based on the status messages. There is a feedback loop whereby the amount of dropped traffic by the service provider is added to the network traffic to keep the mitigation request open and prevent flapping. Likewise, the detection device includes time-to-engage and time-to-disengage timers to further prevent flapping.

  • Patent number: 9356871
    Abstract: A network node may contain a virtual software-defined networking (SDN) switch and a local a management engine (e.g., a software application) for generating performance metrics based on received management plane traffic. Specifically, the virtual SDN switch may identify and forward received management plane traffic to the local management engine. In turn, the management engine evaluates the management plane traffic to generate performance metrics without forwarding the management plane packets to the remote SDN controller. The management engine may compare the metrics to one or more thresholds to determine the current state or health of the data paths in a network. If a threshold is exceeded, the management engine may transmit an alert to the virtual SDN switch to perform a corrective action—e.g., using a backup data path after the primary data path fails.
