    摘要： Techniques for configuring a particular network interface on a particular node at an edge of a provider network to support a particular virtual private network include receiving customer input data. The provider network is a packet-switched network and the particular virtual private network is a link layer virtual private network. The customer input data indicates a topology for customer equipment devices outside the provider network on the particular virtual private network, and may include properties for corresponding interfaces that connect the customer equipment devices to the edge nodes. Based on the customer input data, configuration data is determined for configuring the particular interface at the particular node. The particular node is caused to configure the particular interface based on the configuration data without human intervention. Among other effects, these techniques support zero-touch provisioning of virtual private networks.

    摘要： In one embodiment of the method of adaptively selecting an airlink coding scheme in a telecommunications network, a coding scheme operating region is determined based on a currently used coding scheme and measurements representative of a block error rate. A block error coding scheme is determined based on the determined coding scheme operating region. In another embodiment of the method of adaptively selecting an airlink coding scheme in a telecommunications network, a first coding scheme is determined based on measurements representative of one or more conditional channel quality metrics, and a second coding scheme is determined based on measurements representative of a block error rate. One of the first and second coding schemes is selected as the coding scheme.

    摘要： A method and apparatus for processing a signal on an intermediate network node at an edge of a provider packet-switched network to support a link-layer virtual private network includes receiving a signal on a particular interface. The particular interface is for a direct communication link to a customer network node outside the provider network. It is determined whether the signal indicates that the particular interface is changing from an inactive state to an active state, whereby the signal is called first sign of life (FSOL). If it is determined that the signal is FSOL, then configuration data is determined for configuring the particular interface for the particular virtual private network. The signal is processed based on the configuration data. These techniques allow a dynamic response to new signals on a customer interface without human intervention by the provider.

    摘要： Systems and methods for interconnecting heterogeneous layer 2 virtual private network applications. To facilitate such interconnections, a common addressing scheme for forwarders is provided. All current pseudowire signaling protocols can incorporate this addressing scheme, and therefore establish connectivity among forwarders of different applications. Auto-discovery of remote forwarders is also facilitated by use of a common address family identifier (and subsequent address family identifier) for BGP.

    摘要： A time division multiplexed communications method and system in which time is divided into a number of frames and each frame is divided into N data bursts. The method and system further has a first multiplexer by which a half rate channel is formed as a series of bursts that occur periodically every N bursts once per frame, a second multiplexer in which a full rate channel is formed as two half rate channels on consecutive timeslots, and a transmitter transmitting the full rate channel from a first wireless station to a second wireless station. The full rate channel provided by two half rate channels on consecutive timeslots yields a significantly larger resource pool available for assignment of communication traffic. For full rate channels, the interleaving 0246/1357 method that is used by the system is just as good as the known 0123/4567 method when ideal frequency hopping is used, and the 0246/1357 method performs better when non-ideal frequency hopping or no frequency hopping is used.
