  • Patent number: 11134023
    Abstract: A method for directing network traffic includes, at a network device, receiving network traffic provided by one or more client computing devices. The network device directs the network traffic to a service entity over a first network path. A path quality indicator is received that indicates whether the network traffic directed over the first network path satisfies one or more experience criteria. Based at least on the path quality indicator indicating that the network traffic directed over the first network path does not satisfy the one or more experience criteria, the network device redirects some or all of the network traffic to the service entity over a second network path.

  • Patent number: 10992729
    Abstract: Techniques for endpoint configuration for a communication session are described. According to various implementations, a cloud-based connectivity service maintains network path information that identifies routing paths for routing communication sessions across different networks. The connectivity service is also able to determine configuration information for configuring endpoint devices to participate in a communication session. According to various implementations, configuration information is determined based on a packet quality of a routing path. Thus, an endpoint device can apply the configuration information to attempt to increase packet quality across a routing path, and thus increase media quality for a communication session at the endpoint device.

  • Patent number: 10972510
    Abstract: A media session is established between a first device (e.g., endpoint) and a second device (e.g., endpoint) via a communication network based on connectivity checks performed by the devices. A set of candidate pairs, including network addresses available to the first device and the second device, is generated. Among the candidate pairs of the candidate pair set, a respective priority is initially assigned for connectivity checks. If a connectivity check modification condition is determined to be met for candidate pairs used for connectivity checks, the priority ordering of the candidate pairs is modified to produce a second priority ordering. This second priority ordering assigns a higher priority for a candidate pair which meets the connectivity check modification condition than a candidate pair that does not meet the condition. Based on the modified ordering, connectivity checks are performed, and the media session is configured and established using a candidate pair determined to be valid.

  • Patent number: 10893076
    Abstract: A communication event is established between an initiating device and a responding device under the control of a remote communications controller. In a pre-session establishment phase: a compression dictionary or a dictionary link that identifies an addressable memory location, at which a compression dictionary is held, is received at the initiating device. The received compression dictionary or the received dictionary link is stored in electronic storage of the initiating device. In response to a communication event establishment instruction received at the initiating device after the dictionary or the dictionary link has been received and stored at the initiating device, a session is established between the initiating device and the communications controller by the initiating device transmitting an initial session establishment message—compressed using the dictionary—to the communications controller to establish the communication event.

  • Patent number: 10601879
    Abstract: A media session is configured between a first endpoint and a second endpoint on a communication network based on connectivity checks performed by the endpoints. When a reduced connectivity check condition is met, based on characteristics of the communication network operable between the first endpoint and the second endpoint, a reduced candidate pairing procedure is initiated. The reduced candidate pairing procedure includes connectivity checks performed from the first endpoint with a reduced set of candidate pairs that is smaller than an available set of candidate pairs. The reduced set of candidate pairs is identified based on the characteristics of the communication network at the respective pairs, and a particular candidate pair in the reduced set is determined to be valid based on a result of connectivity checks using the candidate pair.

  • Patent number: 10432591
    Abstract: A communication event is established between an initiating device and a responding device under the control of a remote communications controller. In a pre-communication event establishment phase, a secure connection is established between the initiating device and the communications controller, and session key negotiation messages are exchanged between the initiating device and the communications controller via the secure connection to obtain session key data in an electronic storage location accessible to the initiating device. The secure connection terminates once the session key data has been obtained. In a subsequent communication event establishment phase—after the session key data has been obtained and the secure connection has terminated in the pre-establishment phase—a communication event request is transmitted from the initiating device to the communications controller comprising a payload encrypted with the session key data.

  • Patent number: 10362069
    Abstract: A session is established between an initiating device and a remote device. A session request is transmitted from the initiating device to the remote device according to a preferred networking protocol. If no provisional response to the request is received at the initiating device within an initial duration, the initiating device transmits another session request to the other device according to a non-preferred protocol. If a provisional response to the request is received within the initial duration, the initiating device continues to monitor the elapsed time for an so extended duration. If no final response to the request is received within the extended duration, the initiating device transmits another session request to the other device according to a non-preferred protocol. If a final response is received within the extended duration, a session between the initiating device and the other device is established according to the preferred networking protocol.

  • Patent number: 10237236
    Abstract: A media session is established between a first endpoint and a second endpoint, by transmitting the following messages from the first endpoint in parallel: to the second endpoint, a message indicating a first server network address of a media relay server available to the first endpoint and comprising a unique session identifier; to the media relay server, an activation request comprising the unique session identifier. This activates the session identifier by causing it to be associated at the media relay server with a source address conveyed by the activation request. Once the session identifier has been activated, a media packet received from the second endpoint at the first server network address that comprises the unique session identifier is relayed from the media relay server to the source address for receiving by the first endpoint.

  • Patent number: 10230771
    Abstract: A media session between a first device and a second device is established. The following candidate pairs are determined at the first device, by exchanging network addresses between the devices: (i) a relayed-relayed candidate pair comprising a first media relay server network address and a second media relay server, and (ii) at least one alternative candidate pair. Connectivity checks are performed for at least the alternative candidate pair to determine whether or not the alternative candidate pair is valid. However, the media session is established initially using the relayed-relayed candidate pair without any connectivity checks having been performed by the devices for the relayed-relayed candidate pair and before the connectivity checks for the alternative candidate pair have been completed. If the alternative candidate pair is determined to be valid in the connectivity checks, the established media session is switched to the alternative candidate pair in response.
