A receiver circuit includes a feedback loop including a device. The receiver circuit also includes a register and a sequencer. The sequencer is configured to, responsive to an error signal being below a threshold value, cause the register to store a value indicative of the state of the feedback loop. The sequencer is also configured to cause the feedback loop to transition to a lower power state, and, responsive to a detected wake-up event, cause the previously stored value indicative of the state of the feedback loop to be loaded from the register into the device and enable the feedback loop.

In some embodiments, a non-transitory processor-readable medium includes code to cause a processor to receive at a tunnel server, a data unit addressed to a communication device, and define, a first instance of the data unit and a second instance of the data unit. The first instance of the data unit is sent to the communication device via a first tunnel defined between at least the tunnel server and a first base station associated with a first network. The second instance of the data unit is sent to the communication device via a second tunnel defined between at least the tunnel server and a second base station associated with a second network. The second instance of the data unit is dropped by the communication device when the first instance of the data unit is received before the second instance of the data unit.

When a User Edge Device (UED) receives a unicast packet from a user side, the UED searches in a Media Access Control (MAC) table. When a matching entry in the MAC table is found, the UED forwards the unicast packet locally. When no matching entry in the MAC table is found, the UED transmits the unicast packet to a Network Edge Device (NED). When the UED receives a broadcast packet from the user side, the UED broadcasts the broadcast packet within a same Virtual Local Area Network (VLAN) of a local site and forwards to the NED.

Embodiments of the present invention provide a method for processing a rate group, a method for charging for a data service, and a related device and system, so as to enable a charging system to accurately charge for the data service when the rate group changes. The method includes: determining, by a gateway device, whether a rate group of a service data stream changes; and if the rate group of the service data stream changes, reporting, by the gateway device, charging data to the charging system, so that the charging system performs charging according to the charging data, where the charging data includes service usage information and a reporting reason for reporting the charging data, and the reporting reason indicates a change of the rate group.

Systems, apparatuses, and methods are provided that can reduce problems associated with updates of various applications on various devices, including addition of new services for communicating with another device. A compatibility version (e.g., a minimum compatibility) for a first communication service on a first device can be checked against a compatibility version for communication service on a second device. A comparison of the compatibility versions can determine whether a message can be sent using the first communication service to the second device.

Two embodiments of a one-way network interface card are disclosed, a transmit-only version and a receive-only version. A network controller mounted on the circuit card is coupled to the host computer via a host computer interface. A first processor is coupled to a network interface of the network controller. A second processor has a separate network interface for communicating with a remote computer. A one-way link is coupled between the first processor and the second processor. For the transmit-only embodiment, the one-way link only allows information to be transferred from the first processor to the second processor, and thus information may only pass from the host computer to the remote computer. For the receive-only embodiment, the one-way link only allows information to be transferred from the second processor to the first processor, and thus information may only pass from the remote computer to the host computer.

Various examples describe systems and methods for dynamically and simultaneously assigned channels among multiple nodes in a network that communicates using multiple communication protocols. Aspects of the exemplary examples may include a wireless hub comprising an RF front end receiver that can capture, demodulate and decode a pre-defined band in its entirety. The wireless hub can include one or more medium access control algorithms for assigning channels for multiple nodes to access the predefined band while reduces contention between the nodes that are communicating with the wireless hub.

A system includes first, second, and third apparatuses. The second apparatus converts a first control-command received from the first apparatus to second control-commands compatible with the third apparatus, requests the third apparatus to perform the second control-commands, and notifies the first apparatus of a normal finish of the first control-command when all the second control-commands have finished normally, so that the first apparatus updates a first status of the third apparatus that is held by the first apparatus. The third processor updates a second status of the third apparatus that is held by the third apparatus, upon finishing each second control-command, generates reverse-commands for restoring a result of having executing the second control-commands to a status prior to executing the second control-commands, and, when all the second control-commands have not been executed, restores the second status to a status prior to having executed the second control-commands by executing the reverse-commands.

In various embodiment, the disclosed systems, methods, and apparatuses describe extending the usage spectrum for cable networks (e.g., hybrid fiber-coaxial networks). In particular, embodiments of the disclosure described determining a first portion of a signal having a first frequency band, the first frequency band being greater than approximately 1.2 GHz; determining a second portion of the signal having a second frequency band, the second frequency band being less than or equal to approximately 1.2 GHz; applying an attenuation to the first portion of the signal; and transmitting the second portion of the signal at a flat power-spectral density. Various other related systems, methods, and apparatuses are described.

A method and an associated SDCDN device for delivering data content in a communication network. A software defined content delivery network (SDCDN) monitors one or more performance indicators regarding an exchange of the data content between a first content delivery network (CDN) and at least one client device using a communication channel. The SDCDN determines that at least one performance indicator of the one or more performance indicators exceeds a threshold performance value. The SDCDN identifies a different CDN in operative communication with the at least one client device. The different CDN includes the data content. In response to determining that at least one performance indicator exceeds the threshold performance value, the SDCDN transmits a transfer command to the at least one client device to cause the at least one client device to switch to the different CDN and receive the data content from the different CDN.
