    摘要： A method and system in which a Digital Subscriber Line Access Multiplexer (DSLAM) that is part of a DSL (Digital Subscriber Line) system is able to provide synchronous services to end user equipment connected to the DSLAM via a DSL link and Customer Premises Equipment (CPE). A sniffer device having direct or indirect access to a Primary Reference Clock (PRC) of the DSL system calculates the phase difference between the PRC and the DSLAM's Local Timing Reference (LTR). The phase difference is sent to the CPEs requiring accurate reference clock frequency. The CPEs are able to derive the PRC from the phase difference information transmitted by the sniffer device thus enabling synchronous end user equipment operation.

    摘要： Systems, methods and computer readable media for providing low-latency scheduling on upstream channels. Systems and methods can include a low-latency scheduler and a network interface. The low-latency scheduler can assign a first group of upstream channels for standard communication of packets on a network, and to assign a second group of upstream channels for communication of small upstream packets on the network. The network interface can communicate transmission opportunities identified by the low-latency scheduler to the subscriber devices. The transmission opportunities for subscriber devices are assigned such that devices with a threshold amount of traffic receive transmission opportunities in the first group of upstream channels, and subscriber devices with less than the threshold amount of traffic receive transmission opportunities in the second group of upstream channels.

    摘要： This present invention discloses a type of active and standby board backup and switchover method for access devices, comprising: maintain real time communications between standby board and active board, and check the operating status of the active board at all times; refresh standby board data based on changes to multicast client dynamic data in the active board; perform switchover from the active board to the standby board based on the active board failure detected; the new active board sends a multicast join request to the upstream router based on its saved data. Multicast client dynamic data comprises: multicast client online record, multicast client CDR (Call Detail Record), etc. Adopting the method of this invention guarantees that clients remain online during switchover, ensures an uninterrupted video stream, and thereby ensures that the switchover from active to standby does not significantly affect multicast services for multicast clients. Moreover, clients' multicast service CDR will not be lost, which protects the interests of the provider.
