Virtual Private Network Or Virtual Terminal Protocol (i.e., Vpn Or Vtp) Patents (Class 726/15)
  • Patent number: 11665141
    Abstract: Virtual private network (VPN) service provider infrastructure (SPI) receives a request to access a VPN from a client device. The VPN SPI selects an Internet Protocol (IP) address for access to the VPN by the client device from a pool of IP addresses. The VPN SPI provides access to the VPN for the client device via the IP address. The VPN SPI receives one or more handshake notifications from the client device. The VPN SPI determines that a threshold time period has passed since a latest-in-time handshake notification of the one or more handshake notifications. The VPN SPI disconnects the client device from the VPN in response to determining that the threshold time period has passed. The VPN SPI adds the IP address to the pool of IP addresses in response to disconnecting the client device from the VPN.

  • Patent number: 11658940
    Abstract: A client-side virtual private network (VPN) chaining architecture can provision multiple sessions for multiple VPN clients that are configured to communicate packet traffic in parallel between an end-user device and one or more destinations. The client-side chaining architecture can capture packet traffic per specific users/apps and process (e.g., drop) or reroute the captured packet traffic for different VPN clients. For example, packet traffic can be rerouted from a main VPN client to a secondary VPN client. As such, there can be multiple VPN clients that are simultaneously chained in various ways to the same end-user device.

  • Patent number: 11604892
    Abstract: Disclosed are systems, methods, and non-transitory computer-readable media for standard compliant collection of sensitive data during a communication session. A standard compliant data collection system is used to provide the standard compliant collection of sensitive data. For example, in response to receiving an indication that a user is to provide sensitive data during an active communication session between the user and an agent, a standard compliant data collection mode is invoked. As a result, communication within the active communication session is routed between the user and the standard compliant data collection system via a secure connection, during which sensitive data is collected in a standard compliant manner. Once collection of the user's sensitive data has been completed, the standard compliant data collection mode is ended, and communication within the active communication session is routed between the user and the agent.

  • Patent number: 11575757
    Abstract: A datagram oriented UDP protocol is used for communication between tunnel gateways in a wide area network. Lightweight remote client accesses network services using TCP tunneling. Each remote client maintains one or more UDP/IP+DTLS communication channels to a single member of the gateway group. Gateway servers belonging to the gateway group form some interconnection topology linking each gateway server to each other gateway server, whereby each gateway server maintains a communication channel with every other gateway server in the gateway group. Through the links between gateway servers, a remote client may access any application provided by any gateway server within the gateway group regardless of which gateway server it is connected to, which serves to cloak its communication patterns.

  • Patent number: 11362920
    Abstract: Systems, methods, and apparatus, including computer-readable media, for enhanced network communication using multiple network connections. In some implementations, a networking apparatus concurrently maintains connectivity to a network through each of multiple network transports. The networking apparatus receives one or more packets to be transmitted over the network and classifies the one or more packets to determine a class of service. The networking apparatus selects one of the multiple network transports to transmit the one or more packets based on (i) the class of service for the one or more packets and (ii) measures of expected latency for transmission of the one or more packets over the respective multiple network transports. The networking apparatus transmits the one or more packets using the selected network transport.

  • Patent number: 11277391
    Abstract: A method includes obtaining, by a first network device comprising a processor, characteristic information from an encrypted packet received from a second network device based on a determination that the first network device cannot decrypt the encrypted packet. The first network device is free from having an internet protocol security (IPsec) security association (SA), and the second network device has the IPsec SA. The method also includes generating, by the first network device, generating an informational exchange packet when the first network device obtains, based on the characteristic information, an internet key exchange (IKE) SA corresponding to the characteristic information. The informational exchange packet instructs the second network device to delete the IPsec SA on the second network device. The method further includes sending, by the first network device, the informational exchange packet to the second network device.
