  • Patent number: 10652135
    Abstract: In one embodiment, a multicast listener device floods a path lookup request to search for a multicast tree, and may then receive path lookup responses from candidate nodes on the multicast tree, where each of the path lookup responses indicates a unicast routing cost from a respective candidate node to the multicast listener device, and where each of the candidate nodes is configured to suppress a path lookup response if a total path latency from a source of the multicast tree to the multicast listener device via that respective candidate node is greater than a maximum allowable path latency. The multicast listener device may then select a particular candidate node as a join point for the multicast tree based on the particular node having a lowest associated unicast routing cost to the multicast listener device from among the candidate nodes, and joins the multicast tree at the selected join point.

  • Patent number: 10623306
    Abstract: Systems and methods are provided for dynamically routing packets using multi-flow and multi-path multiplexing connections. A first computing device and second computing device communicate via a plurality of data flows, which may be routed across various network paths. Each flow is defined by a set of network addresses, a set of ports, and a protocol specification, such as UDP. The second device sends information to the first device regarding the various data flows. The first device may send probing packets to facilitate collecting data flow information. Information may include latency, packet loss, and other values. Based on the information received, the first device may select or prioritize data flows to mitigate congestion, and address performance criteria. The first device may also transmit information regarding selected data flows to other devices, allowing the other devices to utilize a selected data flow even if they lack multiplexing capability.

  • Patent number: 10484857
    Abstract: An access point (AP) accepts a communications device to join a wireless communications network. The AP registers a service provided by the communications device. The service is available in accordance with a schedule and a set of service parameters. The AP receives a request from a peer communications device seeking the service. The AP announces availability of the service on behalf of the communications device while the communications device is unavailable. The service is later provided by the communications device to the peer communications device when both devices are available to communicate. By utilizing an always-on AP to announce service availability and to exchange service parameters, fast service discovery can be achieved with low power consumption for both service advertisers and service seekers.
