  • Patent number: 11457487
    Abstract: Systems and methods are described for connecting to a wireless network. In an aspect, when a wireless device is brought to an area in which two wireless networks are accessible, for example a public network and a private network, the device can reject a connection to the public network and connect to the private network based on an association between the device and the user.

  • Publication number: 20220166774
    Abstract: Methods and systems are described for managing communication in a network. A computing device may send a request to a network device for network address. The request may comprise a temporary device identifier associated with the computing device. The network device may send data indicating an option to trust the network device. If the computing device indicates acceptance of the option to trust the network device, additional information may be sent to the network device to allow identification of the computing device from one session to another.

  • Publication number: 20210359913
    Abstract: The disclosure relates to provisioning end devices, such as wireless end devices. In one aspect, a wireless end device may be provisioned with a backend system without requiring a user to enter information to connect the wireless end device to a local wireless network. Moreover, the wireless end device may be provisioned with a single user action. In one example, the single action may be a single click on an activation portal. The single action may trigger the backend system to detect the wireless end device with the help of one or more gateways at one or more premises, and to associate the wireless end device with a user account. The backend system may also facilitate configuring the wireless end device to connect to the proper or desired network at a premises.

  • Publication number: 20210274022
    Abstract: An apparatus, method, system and computer-readable medium are provided for converting traffic of a first communication type to traffic of one or more additional communication types. In some embodiments, the communication types may comprise IP communications, such as IPv4 and IPv6 communications. In some embodiments, multicast communications may be supported. For example, one or more tunnels or channels may be established to support transmitting data, such as content, to one or more destination addresses. In some embodiments, a destination address may be associated with a user device. One or more messages may comprise an address that may be extracted by a device, such as a router, to determine a destination. The one or more messages may comprise a request for service or a request to join a service group.

  • Patent number: 11019181
    Abstract: An apparatus, method, system, and computer-readable medium are described for permitting communications between devices complying with different communication protocols or versions. For example, a computing device may store a map indicative of associations between one or more tunnels or channels and one or more destination addresses. In some examples, a destination address may be associated with a user device. One or more messages may include an address that may be extracted by a device, such as a router, to determine which channel to use in transmitting the message to the user device. One or more messages may include an indication of a channel that may be extracted by the device to determine a destination address of the message.

  • Publication number: 20200412719
    Abstract: A computing device may request service from a service provider, and authorization to receive the service may be based, at least in part, on a network access device that is providing the computing device with network access. The service provider may request a value from the computing device, and the value may be based on address information of the computing device and the network access device.

  • Publication number: 20200358744
    Abstract: A firewall service for a cloud computing environment is described that uses an application identifier-based ruleset to process data packets. An application identifier-based rule may provide an action to be taken on a received packet based on the source application identifier, the destination application identifier, and/or an identification token associated with the source application. A firewall controller may verify applications of the computing environment, provide unique application identifiers, and manage the application identifier rules for one or more firewalls of the computing environments.

  • Publication number: 20200351107
    Abstract: An authentication server may use secure messaging with a remote device prior to authorizing non-secure communications between the remote device and a content server, thereby preventing unauthorized access to the content server. The secure messaging uses such security features as encryption, signatures with authentication certificates, a realm, and/or a nonce. Once non-secure communication is authorized, the remote device may act as a proxy between the content server and a user device connected to the remote device. The authentication server sends timeout notices to the remote device containing an interval and a key. To continue non-secure communications with the content server, the remote device must respond prior to the expiration of the interval by sending a keep-alive message containing the key to the authentication server.

  • Publication number: 20200328958
    Abstract: Systems and methods are described herein for managing peering relationships and applying peering policy between service providers and content distribution networks. Aspects discussed herein relate to establishing secure peering connections between service providers to exchange application and/or network information. In some embodiments, an application peering manager may apply peering policy based on token information or other suitable information configured to uniquely identify an application and/or subscriber. In other embodiments, policy enforcement points or other elements residing within a network may be configured to accept and/or apply peering policy to application sessions.

  • Patent number: 10805291
    Abstract: Systems and methods are described for extending the trust relationship established with a network interface device that provides access to a service provider network that includes an IP-based overlay network. The trust relationship is extended to a consumer premises equipment (CPE) device operating on the overlay network. A network element of the service provider network may authenticate the CPE device when communicating via the overlay network. The service provider network may store an association between network configuration data of the network interface device and the CPE device provisioned via the network interface device and may provide the CPE device with an identity token that encodes this network configuration data. The CPE device may provide the identity token to a network element of the service provider network, and the service provider network may authenticate the identity of the CPE device using the identity token provided.
