  • Patent number: 10291550
    Abstract: Methods, systems, and computer readable media can be operable to facilitate packet bridging based upon a host device address. An access point may identify a source or destination address associated with a received packet, wherein the address identifies an associated host device. When the destination address of a downstream data packet matches an address associated with the access point, the access point may route the packet to a destination within a local area network (LAN). When the source address of an upstream data packet identifies a host device for which communications are to be bridged, the access point may bridge the data packet to a wide area network (WAN). An access point may identify a multicast or broadcast downstream data packet and the access point may flood the packet to both a route and a bridge routine. The bridging determination may be made by a dual-layer WAN or LAN interface.

  • Patent number: 10284320
    Abstract: Methods are disclosed which can be performed by a network node for sending to a wireless device a first synchronization signal and an associated information message, for synchronization of the wireless device with the network node. The network node and the wireless device operate in a wireless communications network. The network node sends the first synchronization signal in N OFDM symbols within a subframe, at least once in a time and frequency position in every one of the N OFDM symbols. N is equal or larger than 2. For each sending of the first synchronization signal, the network node sends an associated information message at a pre-defined time and frequency position in an OFDM symbol. The pre-defined time and frequency position is relative to the time and frequency position of the first synchronization signal. The associated information message is associated with the first synchronization signal.

  • Patent number: 10270686
    Abstract: A method of updating conversation allocation in link aggregation is disclosed. The method starts with verifying that an implementation of a conversation-sensitive link aggregation control protocol (LACP) is operational at a network device of a network for an aggregation port. Then it is determined that operations through enhanced link aggregation control protocol data units (LACPDUs) are possible. The enhanced LACPDUs can be used for updating conversation allocation information, and the determination is based at least partially on a compatibility check between a first set of operational parameters of the network device and a second set of operational parameters of a partner network device. Then a conversation allocation state of an aggregation port of the link aggregation group is updated based on a determination that the conversation allocation state is incorrect, where the conversation allocation state indicates a list of conversations transmitting through the aggregation port.
