  • Patent number: 10084697
    Abstract: Methods and apparatus for Internet-scale routing using small-scale border routers and IP tunneling are described. Each border router is directly connected to a transit provider. Routing protocol peerings may be passed via the border routers through tunnels to a routing service; the routing service and the transit provider router(s) appear to be directly adjacent routing peers. The routing service receives routing data from the transit provider(s), maintains the routing data in a routing table, and processes the routing data in the routing table to select best paths. A mapping service may be informed, by the routing service, of a best exit point (or points) for each Internet prefix of each packet to be routed on the Internet. Outbound packets from devices on the network to the Internet, and inbound packets from the Internet to the network devices, may be encapsulated and passed through tunnels as directed by the mapping service.

  • Patent number: 10075217
    Abstract: UEs capable of RF relay are enabled and disabled under certain conditions. The access node can control the on and off duration of the UE functioning as an RF relay. The access node may only enable RF relay when there is a need by another UE for the RF relay. The UEs selected to relay (or to not relay) may be selected based on their location (e.g., close to a UE that is experiencing poor signal strength). In an embodiment, the RF relay function of UEs are successively turned on by the access node. This causes these UEs to relay the access node's beacon signal. If, after a period of time, the wireless network performance is not improved, these UEs are commanded to disable their RF relays. If the wireless network performance is improved, the UE may be allowed to continue as an RF relay.

  • Patent number: 9998371
    Abstract: A method of communicating packets in a physical host that includes a managed forwarding element (MFE) configured to communicate packets to a set of containers in a data compute node (DCN) hosted by the physical host. The method receives a packet from a particular container in the container DCN. The packet includes a tag that includes an identification of the particular container. The method uses the identification of the particular container included in the tag to identify a port of the MFE that correspond to the particular container. The method removes the tag from the packet. The method forwards the un-tagged packet to the port of the MFE that corresponds to the particular container.

  • Patent number: 9991982
    Abstract: A technique for cancelling inter-cell or intra-cell interference in a cellular communication network is described. A method implementation of that technique performed in an interfered terminal comprises receiving a signal, wherein the received signal comprises an interfering signal destined to at least one further terminal different from the interfered terminal. In a next step, control information pertaining to the at least one further terminal is determined and the interfering signal is decoded based on the control information so as to generate decoded information. Then, the interfering signal is re-generated from the decoded information and the control information. Based on the re-generated signal the interfering signal is cancelled from the received signal.
