  • Patent number: 11522796
    Abstract: In some embodiments, a method sets a threshold for utilization of a first table, wherein the utilization is based on layer 3 addresses and layer 2 addresses being stored in the first table. When a utilization of the first table does not meet the threshold, the method stores a layer 3 address in the first table. The first table uses a first type of lookup to determine a next hop address for the layer 3 addresses or the layer 2 addresses, and the first table also stores one or more layer 2 addresses. When the utilization of the first table meets the threshold, the method stores the layer 3 address in a second table where the second table uses a second type of lookup to determine the next hop address for layer 3 addresses.

  • Patent number: 11516778
    Abstract: A user equipment has been allocated uplink resources, e.g. interlaced uplink channel resources, e.g. interlaced physical uplink shared channel (PUSCH) resources, and non-interlaced uplink channel resources. The UE receives cancellation indication (CI) information which rescinds the allocation for a portion of the previous granted resources. CI is communicated using different formats for resources which are in blocks and resources which are interlaced. The CI for the interlaced resources uses a more efficient format with less overhead to communicate frequency information corresponding to the cancellation for the interlaced channel.

  • Patent number: 11470009
    Abstract: Techniques for implementing multi-table OpenFlow using a parallel hardware table lookup architecture are provided. In certain embodiments, these techniques include receiving, at a network device from a software-defined networking (SDN) controller, flow entries for installation into flow tables of the network device, where the flow entries are structured in a manner that assumes the flow tables can be looked-up serially by a packet processor of the network device, but where the flow tables are implemented using hardware lookup tables (e.g., TCAMs) that can only be looked-up in parallel by the packet processor. The techniques further include converting, by the network device, the received flow entries into a format that enables the packet processor to process ingress network traffic correctly using the flow entries, despite the packet processor's parallel lookup architecture, and installing the converted flow entries into the flow tables/hardware lookup tables.

  • Patent number: 11438034
    Abstract: A method for a Physical Random Access Channel (PRACH) retransmission, executed by a UE wirelessly transmitting and receiving to and from a cellular station, operates by performing a first PRACH transmission or retransmission using a first spatial domain transmission filter on first PRACH resources which are associated with a first downlink reference signal. After the first PRACH transmission or retransmission, the method performs a second PRACH retransmission using a second spatial domain transmission filter on second PRACH resources which are associated with a second downlink reference signal. Finally, method operates without incrementing a power ramping counter in response to the UE selecting the second spatial domain transmission filter different from the first spatial domain transmission filter, or incrementing the power ramping counter in response to the UE selecting the second downlink reference signal different from the first downlink reference signal.

  • Patent number: 11431829
    Abstract: A system adaptably directs packet flows to packet processing elements based on OSI layer characteristics and, when necessary, inspection of data payloads. Characteristics of parsed data flows are identified. A comparison ensues. Upon recognition of a match, the entirety of the packet flow is directed to a linked packet processing element. When a match does not occur, the packet flow is directed to a second analysis tier whereby data payloads of the flow are examined. Characteristics from the data payload analysis are compared to entries in a database. Upon a match being recognized the matching packet flow is directed to the packet processing element. Features of packet flow having undergone data payload analysis are captured and used to update the database of prior associations so that any subsequent receipt of similar packet flows will be forwarded to the linked packet processing element without having to conduct a data payload analysis.

  • Patent number: 11425717
    Abstract: Configuration of a communication module based on determination of an idle time metric is described. In one embodiment, signal strength data representative of composite signal strength indicators of a group of frequency channels utilized by the communication module is determined. A composite indicator of the composite signal strength indicators can be employed that comprises multiple signal strength indicators, sampled over time, of a first channel of the group of frequency channels. Respective values for the composite indicator can be assigned in response to comparisons of the multiple signal strength indicators to one or more defined threshold(s). An idle time metric of the first channel can be determined based on a combination of the respective values and a best channel from among the group of frequency channels can be determined based on the idle time metric. The communication module can be updated to communicate via the best channel.
