  • Patent number: 10536297
    Abstract: A method for transmitting MAC frames between hosts/remote machines and virtual machines across network elements (e.g., switches, routers, and multilayer switches) that conventionally do not hold capacity to address VXLAN encapsulation to any and all possible destination VTEPs within expanding data centers. More specifically, the method permits a network element the functionality of retaining VXLAN encapsulation table entries corresponding to VTEPs on Top of Rack (ToR) switches versus to VTEPs on hosts that reside under those ToR switches. This use of indirect VXLAN bridging may reduce the number of required VTEPs stored on a network element for the purposes of performing VXLAN encapsulation, thereby once again establishing the capability for packets to reach any arbitrary destination VTEP as data centers scale.

  • Patent number: 10382992
    Abstract: Techniques may be used for interference measurement and management in directional mesh networks, including centralized and/or distributed approaches. A centralized node, such as an operations and maintenance (OAM) center, may use feedback from nodes in the mesh network to partition the nodes in the mesh network into clusters based on interference levels. Interference measurement reports may be used by the centralized node to update cluster membership. An initiating node in the mesh network may use topographical information to generate an initial interference cluster, and interference measurement frame (IMF) scheduling information may be used to schedule transmissions within the interference clusters. Techniques for opportunistic measurement campaigns, simultaneous measurement campaigns, link failure detection, and link re-acquisition in directional mesh networks may also be used.

  • Patent number: 10361775
    Abstract: A retro-directive antenna system on a mobile airborne platform for communication with a ground hub located within a coverage area. The system comprises an antenna array, a receive beamforming network, and a diagnostic processor. The antenna array comprises a plurality of antenna elements. The receive beamforming network generates concurrently a plurality of receive beams for the respective antenna elements. The receive beams correspond to respective beam positions within the coverage area. A first beam position points to the ground hub and a corresponding receive beam receives a target signal from the ground hub. The diagnostic processor determines a best position for the first beam position based on a ranking system and controls the receive beamforming network by updating the beam positions based on the best position for the first beam position.

  • Patent number: 10313208
    Abstract: The disclosure relates to a method of resource allocation for supporting communications with a wireless device is provided. The method is performed in a network element of a wireless communication network. The method comprises differentiating (2710) between synchronous network functions and asynchronous network functions. The synchronous and asynchronous network functions are associated with the provision of communication services to the wireless device. The synchronous network functions have requirements on processing timing which are strictly dependent on timing of a radio link used for communicating with the wireless device. The asynchronous network functions have requirements on processing timing not strictly dependent on the timing of the radio link. The method also comprises allocating (2720) resources of the wireless communication network for the instantiation of a first network function based on whether the first network function is synchronous or asynchronous.

  • Patent number: 10305951
    Abstract: Devices, systems and methods are disclosed for allowing a media device to select a preferred configuration and send instructions to a remote device to connect to the media device using the preferred configuration. For example, the media device may choose between a direct configuration (e.g., media device communicates with the remote device directly via a first wireless network associated with the media device) or an indirect configuration (e.g., media device communicates with the remote device via a second wireless network associated with an external access point). The media device may select the preferred configuration based on data rates and/or airtime values determined based on the first wireless network and the second wireless network. Prior to connecting using the preferred configuration, the remote device may determine a frequency channel corresponding to the preferred configuration and may instruct a remote control to connect to the remote device using the frequency channel.

  • Patent number: 10270660
    Abstract: A network architecture includes a gateway that terminates broadband service at a particular location, e.g., at the entry to a house or business. The gateway may execute a MoCA network controller (NC) that manages a network of MoCA nodes connected by cable connections. The gateway distributes content to the MoCA nodes on the network, using a logical star topology over the physical tree topology connections. The NC allocates greater downlink (gateway to MoCA node) bandwidth compared to uplink (node to gateway) bandwidth. Because the gateway terminates the broadband service, the network architecture frees very significant spectrum over the cable connections, permitting, for instance, the transmission of hundreds of Mbps of broadband content streams to the MoCA nodes.

  • Patent number: 10263753
    Abstract: In order to improve the quality of communication between electronic devices, one or more sub-channels used during communication between the electronic devices are dynamically modified based on one or more performance metrics and allowed transmit powers of the sub-channels. In particular, when the one or more performance metrics indicate that a distance between the electronic devices falls within a mid-range of distances, the one or more performance metrics may be used to guide selective changes to the sub-channels used during the communication based on the allowed transmit powers. The changes to the sub-channels used during the communication may increase, decrease or leave the total bandwidth unchanged. Moreover, by changing the sub-channels used during the communication, the allowed transmit power(s) of the sub-channel(s) used may be increased, which may improve the performance during the communication.
