摘要： A Layer Two Tunnel may be established between one or more user devices and a tunnel aggregator device via a home gateway. By establishing the Layer Two Tunnel, the tunnel aggregator and other entities of an access network, such as a multi-system operator (MSO) network, may be configured to identify individual user devices at a customer premise. As a result, the network operator may be able to offer individual user device and user based services. Additionally, operations, such as DHCP, NAT, etc., that may otherwise be conducted at a customer premise, such as by a home gateway, may be performed at the MSO and/or in the cloud.

摘要： Systems, methods, and apparatus for rerouting network traffic flows based on selection criteria are provided. Routers forming data flow paths between network devices in a network may be polled. In response to the poll, network status information may be received from the routers. Based at least in part on the received status information, a rerouting event associated with a first data flow over a first data flow path may be received. Based on one or more selection criteria, a second data flow path may be selected for the first data flow. The first data flow may then be rerouted over the second data flow path.

摘要： Technologies are provided for the monitoring of a power grid using power measurements using cable network devices. An embodiment of the technologies includes a computing system that can cause the cable network devices to perform power measurements. The cable network devices include customer premises equipment. The computing system also can receive first data defining observed values corresponding to the power measurements. A first observed value of the observed values results from a first power measurement of the power measurements. The computing system also can obtain second data defining times corresponding to the power measurements, where the first power measurement occurs at a first time of the defined times. The computing system can then generate status data by analyzing the observed values, where the status data represent respective power utilization states of the cable network devices. The computing system can provide the status data to a remotely located computing device.

摘要： Technologies are directed to active taps and distributed gain architectures in a cable network. In some embodiments, an active tap includes multiple ports, where at least one of the multiple ports can receive radio-frequency (RF) signals from a customer premises equipment (CPE) and/or can transmit RF signals to the CPE. The active tap also can include a switch module and a controller device functionally coupled to the switch module. The controller device can monitor one or several performance metrics defining respective signal attributed. The controller device also can control the operation of the tap device based on a magnitude of a performance metric. The active tap also includes a cable modem that can report magnitudes of performance metric(s) to a network device or a user device. A distributed gain architecture can include any combination of passive taps and active taps functionally coupled to a fiber node in the cable network.

摘要： A request to establish a tunnel over a layer three network connection may be received by a proxy device. The tunnel may then be established by the proxy device. Device information and wireless network information from a mobile device may be received over the tunnel. Responsive to receipt of the device information and the wireless network information, source and destination addresses may be assigned to the mobile device. The source and destination addresses may correspond to the device information and the wireless network information. Internet protocol (IP) packets may be received, via the tunnel, from the mobile device. Layer two frames may be generated utilizing the assigned source and destination addresses. The layer two frames may encapsulate each of the IP packets. The layer two frames may be transmitted to a layer two service function chain (SFC) infrastructure.
