摘要： A network device for providing single-carrier quadrature amplitude modulation (SC-QAM) downstream channel fast pre-scanning. An orthogonal frequency-division multiplexing (OFDM) downstream (DS) channel scan in a foreground process and a single-carrier quadrature amplitude modulation (SC-QAM) DS channel scan in a background process are simultaneously performed. When a first OFDM downstream channel is locked onto, OFDM downstream channel is paused while scanning for SC-QAM downstream channels continues. SC-QAM DS channels identified in the background process are stored in a table. Based on a scan of all OFDM channels and failure to lock onto any OFDM DS channels, the SC-QAM DS channel scan in the background process is stopped and a normal SC-QAM DS channel scan is started. SC-QAM DS channels in the table are scanned first to provide fast pre-scanning. A modem becomes operational with a qualified SC-QAM DS channel obtained from the table.

摘要： An electronic device for processing real-time-streaming-protocol (RTSP) packets in a network to provide enhanced video-on-demand (VOD) services is provided. The electronic device includes a user interface, a non-transitory memory configured to store instructions including an application layer gateway (ALG) module and network service software, and a hardware processor. The hardware processor is configured to execute the instructions to store a list of mac-bridge clients that includes a MAC address and a MAC mask corresponding to each mac-bridge client, and determine whether at least one of the source and destination MAC address of a received RTSP packet is on the list. When at least one of the source and destination MAC address is on the list, the RTSP packet is processed using the network service software and a next RTSP packet is received; otherwise, the received RTSP packet is processed using the ALG module.

摘要： Some aspects of the present publication relate to a cable modem, i.e. CM, comprising a memory unit, in which instructions are saved, and a processor. The processor is configured to execute the instructions saved in said memory unit so that said electronic device executes the following operations: Receiving special service flow configuration information; said special service flow configuration information comprises information, which is configured by users and used for enabling the establishment of special service flows with one or a plurality of client stations connected with the CM; and establishing said special service flows with the cable modem terminal system, i.e. the CMTS, using the dynamic service flow technology based on said special service flow configuration information; said special service flows are only used for the communication with said one or plurality of client stations.

摘要： A wireless master device to remotely perform network speed tests on a wireless client device that is not in the possession of the user. A user interface (UI) is provided that displays a list of client devices that may be selected to be the wireless master device and a list of client devices that may be selected to perform the speed test. A start instruction is wirelessly sent to start the speed test on the selected client device. Network speed test results of the client device are received by the wireless master device and presented in the UI. The UI presents options for selecting a type of speed test to perform. The UI includes an area where messages and the test results are presented.
