摘要： Systems and methods are provided to facilitate the distribution of audio signals over wireless networks. In one implementation, an audio system includes a head end having an encoder and a wireless network interface. Audio signals associated with a plurality of audio channels are processed by the encoder to provide an encoded signal in accordance with an audio codec. The encoded signal can be provided to a wireless network by the wireless network interface as a plurality of data packets associated with a network address in accordance with a wireless networking protocol, such as an IEEE 802.11 protocol. One or more remote endpoints can also be provided to receive the data packets from the wireless network, assemble the data packets to obtain the encoded signal, and extract at least one of the audio signals from the encoded signal in accordance with the audio codec. Multicast and unicast implementations are also provided.

摘要： In one embodiment, an edge router of a local computer network snoops client-server protocol configuration information of a customer-premises equipment (CPE) device. From the snooping, the edge router may identify an Internet Protocol version 6 (IPv6) transition option in place at the CPE device along with associated configuration parameters for the IPv6 transition option. As such, the edge router may then advertise the IPv6 transition option along with associated configuration parameters to one or more border/relay routers of the local computer network to cause the one or more border/relay routers to provision themselves with the IPv6 transition option and associated configuration parameters.

摘要： A method in an example embodiment can include polling a first cable modem in a cable network and receiving a first response message from the first cable modem identifying a downstream frequency detected by the first cable modem. The method further includes determining the downstream frequency is split between at least two fiber nodes and determining a cable modem termination system (CMTS) service group topology, where the topology includes the at least two fiber nodes. In specific embodiments, determining that the downstream frequency is split is based on at least the first response message from the first cable modem and a second response message from a second cable modem. In more specific embodiments, the method includes constructing a hybrid fiber-coaxial (HFC) topology map of the cable network based on at least the first and second response messages, where the HFC topology map indicates the CMTS service group topology.

摘要： In one example, a routing protocol is used to propagate or flood information over a network of Cable Modem Termination Systems (CMTSs) in response to a fiber node split that changes which of the CMTSs a cable modem is coupled thereto. The network processes the information and dynamically changes a pseudowire placement to maintain the Layer 2 Virtual Private Network (L2VPN) connectivity among cable modems of different CMTSs after the fiber node split.

摘要： In one embodiment, a clock on a network device is initialized, and then a first timing message is received at the network device from a reference device having a first timestamp indicating when the first timing message was transmitted from the reference device. The network device may then determine and store a one-way delay from the first timestamp to a first time at which the first timing message was received at the network device. In response to restarting the clock, the network device may receive a second timing message from the reference device having a second timestamp indicating when the second timing message was transmitted from the reference device. The network device may then calibrate the clock such that a second time at which the network device received the second timing message is the second timestamp plus the stored one-way delay.

摘要： In one embodiment, label distribution sessions are established between a Modular Cable Modem Termination System (M-CMTS) core and one or more remote PHYs. The label distribution sessions facilitate association of labels with either Radio Frequency (RF) channels or groups of the RF channels that extend from the remote PHYs to one or more cable modems. The labels are then used to facilitate communications between the M-CMTS core and the remote PHYs over a MultiProtocol Label Switching (MPLS) network.

摘要： Method and system for providing ad-splicer N+1 redundancy in a network by employing IP network intelligence and techniques to facilitate a redundant ad-splicer assuming, within a few seconds, the functionality of the failed primary ad-splicer. The network triggers the installation of unicast and multicast routes on an interface by tracking one or more unicast routes to deliver the unicast and (pre-spliced) multicast traffic to the redundant ad-splicer. The network dynamically adjusts the multicast trees to continue to deliver the post-spliced multicast traffic to the intended receivers.
