  • Patent number: 11096190
    Abstract: Methods and systems for wireless packet switching include determining a schedule for transceivers in an enclosure. The schedule specifies which of the transceivers will act as a transmitter and which will act as a receiver. A beamforming direction for transmitting data from each transmitter to each corresponding receiver is determined. It is determined that an angle of the beamforming direction for at least one transmitter is lower than a minimum angle. Data is transmitted from a transmitter to the corresponding receiver by a wired connection, responsive to the determination that the angle of the beamforming direction is lower than a minimum angle.

  • Patent number: 11070471
    Abstract: A switch fabric has a plurality of leaf switches, each leaf switch having a local tenant identifier (LTID) table, a local forwarding information base (LFIB) table, and a forwarding engine coupled to the LTID table and LFIB table. Each leaf switch has downlink ports operative on VLAN packets such as those generated by Container/Virtual machines (CVM), each leaf switch also having a reconfigurable uplink port for transmission and reception of VxLAN packets formed from VLAN packets which have a destination address which is not local to a particular leaf switch. The uplink ports are coupled to the leaf ports of one or more spine switches, each spine switch having a Global Forward Information Base (GFIB) table slice coupled to a VxLAN forwarder which receives VxLAN packets, de-encapsulates them and uses the GFIB table slice to form new VxLAN packets transmitted to a different leaf port.

  • Patent number: 11012209
    Abstract: Provided is a wireless communication user equipment that wirelessly communicates. The wireless communication user equipment includes a communication module; and a processor configured to control the communication module. The processor is configured to receive a demodulation reference signal (DM-RS) of data channel and receive the data channel based on the DM-RS of the data channel, wherein a time-frequency resource mapped to the DM-RS is predetermined. When the time-frequency resource mapped to the transmission of the DM-RS of the data channel overlaps with the time-frequency resource mapped to a different purpose from the transmission of the DM-RS, the processor is configured not to receive the DM-RS in a resource element (RE) overlapping with the time-frequency resource mapped to the different purpose in the time-frequency resource mapped to the transmission of the DM-RS. The DM-RS is a reference signal specific to the wireless communication device.

  • Patent number: 10924303
    Abstract: A secure training sequence (STS) is included in wireless packets communicated between electronic devices to assist with channel estimation and wireless ranging. The STS includes multiple STS segments generated based on outputs from a cryptographically secure pseudo-random number generator (CSPRNG), the STS segments being separated by guard intervals and formatted in accordance with an 802.15.4 data symbol format that uses burst position modulation (BPM) and binary phase shift keying (BPSK) to map bits from the CSPRNG to burst positions and pulse polarities for the STS symbols. Both a first electronic device, which generates the STS, and a second electronic device, which estimates a communication channel using the STS, have prior private knowledge of cryptographic keys required to generate a non-repetitive single-use pseudo-random (PR) sequence by the CSPRNG. The STS includes two burst position intervals per STS symbol and two possible burst positions within each burst position interval.

  • Patent number: 10917338
    Abstract: A system and method for building a data structure for determining if multiple routing or forwarding tables yield the same or different forwarding behaviors. VeriTable uses a single tree/trie traversal to quickly check if multiple forwarding tables are forwarding equivalent, yield routing loops, or black holes. VeriTable also uses the Longest Prefix Matching rule for lookups, e.g., checking if route updates in control plane are consistent with the ones in forwarding plane. VeriTable can be applied to network-wide abnormality diagnosis of network problems, such as scalable and efficient forwarding loop detection and avoidance in the data plane of a network. In addition, VeriTable can be extended to handle incremental updates applied to the forwarding tables in a network.

  • Patent number: 10892978
    Abstract: Disclosed herein are systems and methods for multi-level classification of data traffic flows based on information in a first data packet for a data traffic flow. In exemplary embodiments of the present disclosure, a key can be generated to track data traffic flows by application names and data packet information or properties. Based on these keys, patterns can be discerned to infer data traffic information based on only the information in a first data packet. The determined patterns can be used to predict classifications of future traffic flows with similar key information. In this way, data traffic flows can be classified and steered in a network based on limited information available in a first data packet.
