  • Patent number: 11019545
    Abstract: A connection between two UEs is identified by a single connection identifier. Different streams are transmitted over different wireless links with potential redundancy between streams. Initially a first WiFi link is used to communicate with the second UE. After the first UE decides it will handoff to a second WiFi AP it establishes a connection with a cellular AP and then communicates a second stream corresponding to the same connection. The first and second streams initially communicate the same content. The first WiFi link is terminated, but the second stream continues to communicate content. The first UE then establishes a second WiFi connection with a second WiFi AP and communicates a third content stream of the first connection to second UE via second WiFi link. The third stream initially communicates information also communicated over second stream. The cellular link is terminated. The second WiFi link is used to communicate content.

  • Patent number: 10574334
    Abstract: A wireless relay manages Radio Frequency (RF) interference. A wireless access point in the relay wireless exchanges user data with wireless user devices using an amount of Carrier Aggregation Secondary Component Carriers (CA SCCs) in an RF band. A wireless network transceiver in the relay wireless exchanges the user data with a wireless communication network using a number of RF channels in the RF band. In response to excessive RF interference, the wireless access point wireless exchanges subsequent user data with the wireless user devices using a lower amount of the CA SCCs in the RF band. In response to the excessive RF interference, the wireless network transceiver wireless exchanges the subsequent user data with the wireless communication network using a lower number of RF channels in the RF band.

  • Patent number: 10511529
    Abstract: A packet processing method for a virtual switch is carried out in a virtual switch under the SDN architecture. The method presets a signature pre-computation table including plural destination addresses and signatures corresponding to the destination addresses. With the installation of the signature pre-computation table, the destination addresses fall into packets of the signature pre-computation table without requiring computing the signature of the packet. The method simply obtains the corresponding signature according to the destination address of the packet destination address, and thus saves the time required for processing a packet and improves the throughput of the virtual switch.

  • Patent number: 10164868
    Abstract: A physical host executes a virtual machine monitor (VMM) that instantiates a source virtual machine (VM). In response to the VMM receiving from the source VM a packet specifying a first destination address of a destination VM and a second destination address of a default gateway, the VMM determines whether the packet can be communicated to the destination VM without the packet being routed by the default gateway. In response to the VMM determining that the packet can be communicated to the destination VM without the packet being routed by the default gateway, the VMM forwards the packet to the destination VM such that the packet bypasses routing by the default gateway.
