  • Patent number: 10778567
    Abstract: Apparatus and methods described herein relate to an apparatus including a set of ports and a processor operatively coupled to each port of the set of ports. A port from the set of ports can be associated with a port of a multi-chassis aggregate (MCAE) interface and a virtual local area network (VLAN). The processor can generate an untagged data unit and tagged data units. The processor can send the untagged data unit and the tagged data units via the port from the set of ports, and can receive a tagged data unit included in the tagged data units, and/or the untagged data unit. The processor can also forward the received data unit to a destination network peer when the received tagged data unit is associated with the VLAN, and can disable the port of the MCAE interface in response to the port from the set of ports receiving the data unit, when the received data unit is associated with the VLAN.

  • Patent number: 10771593
    Abstract: Embodiments discussed herein refer to systems, methods, and circuits for managing and establishing contactless communications lanes between two contactlessly coupled systems. A contactless communication lane can be formed for each coupled pair of contactless communication units existing in the two systems. A contactless communications interface can enable software-defined connectivity that manages use of the contactless communication data lanes to enable data communications according to a selected one of a plurality of communications interfaces. The contactless communications interface may serve as a protocol translator and virtualization layer for enabling higher level software such as an operating system of a first system to communicate with a second system without requiring interface protocol specific hardware and software. This advantageously simplifies hardware and software components needed to simultaneously service a multitude of interface protocols.

  • Patent number: 10742545
    Abstract: A multicast system includes a source device and a plurality of receiver devices connected by switches that are also coupled to a switch controller. The switch controller receives source device information for the source device from its connected first switch, and receives receiver device information for each of the receiver devices from their respective connected second switches. The switch controller uses the source device information and receiver device information to construct a multicast tree that includes switches capable of transmitting multicast communications from the source device to each of the receiver devices. The switch controller then programs at least some of the switches so that a multicast data communication from the source device is segment routed to a third switch, and replicated by the third switch to produce replicated multicast data communications that are each segment routed to at least some of the receiver devices through their respective second switches.

  • Patent number: 10708175
    Abstract: Systems, methods, and network topology for network address translation (NAT) are disclosed. In some embodiments, a cluster of NAT devices shares at least one backup NAT device configured to back up all or some of the NAT devices in the cluster. Each NAT device, including the backup NAT device, advertises its status at a regular interval to a router. If the router determines that an active NAT device is no longer advertising its status, the router can send data to the backup NAT. In some embodiments, the router routes traffic to active and backup devices based on networking protocols such as Border Gateway Protocol (BGP) and/or Open Shortest Path First (OSPF). The router can also route data to NAT devices using a round-robin algorithm.

  • Patent number: 10680623
    Abstract: A local oscillator (LO) distribution system is described. The LO system includes a plurality of phase-locked loop (PLL) modules coupled to each other in a one-way, circulant coupling topology. Each PLL module receives a reference clock signal and outputs an output LO signal. Each PLL module provides a local LO signal to an adjacent downstream PLL module, where the local LO signal is a frequency divided version of the output LO signal. Each PLL module receives an adjacent LO signal from the adjacent upstream PLL module. The phase of the output LO signal is made to be coherent with the phase of the reference clock signal and the phase of the adjacent LO signal, using a feedback loop.

  • Patent number: 10681160
    Abstract: Resource processor circuitry parses responses corresponding to a resource of a request from other responses corresponding to other resources embedded in the resource of the request. This parsing reduces the shear amount of data needed to be processed by the resource processor circuitry, thereby improving performance of the resource processor circuitry. The resource processor circuitry parsing uses a pattern matching routine to parse the response corresponding to the resource of the request from the responses corresponding to other resources embedded in the resource of the request. Thereafter, the resource processor circuitry includes the response corresponding to the resource of the request to a catalog.

  • Patent number: 10680778
    Abstract: Controlling and reducing overhead in control channels in 5G or other next generation communication systems is provided herein. In connection with a data transmission between a device and a network node device, an overhead management component (OMC) can analyze one or more factors associated with the device, including speed or Doppler metric(s) of the device, type of service associated with the device, historical HARQ statistics for the device, configured threshold value for CSI estimation, device capability regarding redundancy version support, or another factor(s). Based on analysis results, OMC can determine whether to utilize a single redundancy version state or a multiple redundancy versions state. If the single redundancy version state is selected, OMC can generate control information that does not include redundancy version information, the control information being communicated via a control channel. OMC can communicate RRC signal to the device to indicate the determined redundancy version state.
