  • Patent number: 10652086
    Abstract: A method in a network device is described and includes selecting, based upon a service request, one or more device gateways from a plurality of device gateways that are communicatively coupled with a plurality of low powered devices. The low powered devices do not include Subscriber Identity Modules. Configuration information is transmitted over a public network to the selected device gateways, causing the selected device gateways to configure ones of the low power devices to perform actions according to the service request. Data is received from the selected device gateways over the public network that was generated by the configured low power devices. One or more GPRS Tunnel Protocol (GTP) tunnels are established with a Packet Data Network (PDN) gateway of a mobile network operator, and the received data is sent over the one or more GTP tunnels to be processed by the mobile network operator.

  • Patent number: 10305769
    Abstract: According to another embodiment of the invention, TWAMP path discovery is performed to determine a sequence of IP addresses of a forward direction TWAMP E2E path to be traversed by two different TWAMP test sessions between a Sender and a Reflector. Then, additional TWAMP test request packets are transmitted for the different TWAMP test sessions; and TWAMP test reply messages are received responsive to respective ones of the TWAMP test request packets. Responsive to the TWAMP test reply messages, a PM is determined that is specific to the different sequences of IP addresses of the forward direction TWAMP E2E paths traversed by the two different TWAMP test sessions.

  • Patent number: 10050840
    Abstract: Methods of Internet of Things (IoT) device access are disclosed. In one embodiment, a method is implemented in a software-defined networking (SDN) controller. The method includes receiving a node discovery request from a network device that receives a unicast neighbor solicitation message from an electronic device that supports IPv6. The unicast neighbor solicitation message contains an IPv6 address to be registered. The method also includes causing a device entry to be generated in a device discovery table, and transmitting an acknowledgment to the network device upon the device entry being generated successfully. The method continues with transmitting a request to the network device to generate a flow table entry for the electronic device based on a policy table. The flow table entry includes an operation to be performed, and the network device is to perform the operation on a packet received matching the flow table entry.

  • Patent number: 9497116
    Abstract: A scheme for providing access to 6LoWPAN data in a wireless access network. In one embodiment, a Digital Unit (DU) of the wireless access network is provided with IP bridging functionality for packaging 6LO data as a control channel message. When the DU element receives 6LO data from an external router, the data is packaged in a format specified for a control channel associated with a CPRI link coupling to a Radio Unit (RU). The bridging functionality is operative to transmit the control channel message (including the packaged 6LO data packets) to the RU element based on an address mapping between the destination IP address of the 6LO data packets and an address of the 6LO endpoint coupled to the RU element.
