20130148660 | MULTICAST IMPLEMENTATION IN A LINK STATE PROTOCOL CONTROLLED ETHERNET NETWORK - Forwarding state is installed for sparse multicast trees in a link state protocol controlled Ethernet network by enabling intermediate nodes to install state for one or more physical multicast trees, each of which may have multiple logical multicast trees mapped to it. By mapping multiple logical multicasts to a particular physical multicast, and installing state for the physical multicast, fewer FIB entries are required to implement the multiple multicasts. Mapping may be performed by destination nodes before advertising membership in the physical multicast, or may be performed by the intermediate nodes before installing state when a destination node advertises membership in a logical multicast. Intermediate nodes will install state for the physical multicast tree if they are on a shortest path between a source and at least one destination of one of the logical multicasts that has been mapped to the physical multicast. | 2013-06-13 |
20130148661 | Performing Multicast Communication In Computer Networks By Using Overlay Routing - An overlay protocol and system for allowing multicast routing in the Internet to be performed at the application level. The overlay protocol uses “native” Internet multicast and multicast routing protocols to route information, according to overlay routing tables. Overlay groups are mapped to native multicast groups to exploit native multicasting in regional or local forwarding domains. Use of the overlay protocol allows overlay distribution to be handled in a more intelligent and bandwidth-managed fashion. Overlay routers are placed at each of several local area networks, Internet service provider's point of presence, enterprise, or other cohesively-managed locations. The overlay computers are configured according to bandwidth and security policies, and perform application-level multicast distribution across the otherwise disjoint multicast networks by using the overlay routing. The result is an overlay multicast network that is effectively managed according to local network management policies. Application-level control can be applied to the transferred data at the overlay routers. | 2013-06-13 |

The switch determines if the external link is configured in a link aggregation group (LAG) and if the SMAC address is newly learned. In response to a determination that the external link is configured in a LAG and the SMAC address is newly learned, the switch associates the SMAC with the virtual bridge and communicates the association to a plurality of bridges in the data network. | 2013-06-13 |

20130148709 | Interface with Variable Data Rate - A device includes a transmitter coupled to a node, where the node is to couple to a wired link. The transmitter has a plurality of modes of operation including a calibration mode in which a range of communication data rates over the wired link is determined in accordance with a voltage margin corresponding to the wired link at a predetermined error rate. The range of communication data rates includes a maximum data rate, which can be a non-integer multiple of an initial data rate. | 2013-06-13 |
20130148710 | METHOD, APPARATUS, AND SYSTEM FOR TIME SYNCHRONIZATION OF XDSL - The present invention provides a method, an apparatus, and a system for time synchronization of an xDSL. The method includes: transmitting, by a customer premises equipment, a first symbol to a central office equipment, and obtaining time Ts | 2013-06-13 |
20130148711 | SOFT LINEAR AND NON-LINEAR INTERFERENCE CANCELLATION - A two stage interference cancellation (IC) process includes a linear IC stage that suppresses co-channel interference (CCI) and adjacent channel interference (ACI). The linear IC stage disambiguates otherwise super-trellis data for non-linear cancellation. Soft linear IC processing is driven by a-posteriori probability (Apop) information. A second stage performs expectation maximization/Baum Welch (EM-BW) processing that reduces residual ISI left over from the first stage and also generates the Apop which drives the soft linear IC in an iterative manner. | 2013-06-13 |
20130148712 | CONDITIONAL ADAPTATION OF LINEAR FILTERS IN A SYSTEM HAVING NONLINEARITY - Described embodiments adjust configurable parameters of at least one filter of a communication system. The method includes conditioning, by an analog front end (AFE) of a receiver in the communication system, an input signal applied to the receiver. Sampled values of the conditioned input signal are generated and digitized. An error detection module generates an error signal based on digitized values of the input signal and a target value. A decision feedback equalizer generates an adjustment signal based on the digitized values of the input signal and values of the error signal. A summer subtracts the adjustment signal from the conditioned input signal, generating an adjusted input signal. An adaptation module determines a conditional adaptation signal based on a comparison of sampled values of the adjusted input signal and values of the error signal. The adaptation module adjusts a transfer function of at least one filter based on the conditional adaptation signal. | 2013-06-13 |
20130148713 | METHOD AND APPARATUS FOR TRANSMITTING AND RECEIVING SIGNALS BASED ON DUAL COMPRESSIVE SENSING IN WIRELESS COMMUNICATION SYSTEM - A method for transmitting signals based on dual sensing in a wireless communication system is disclosed. One or more sensor nodes receive Gaussian codes corresponding respectively to the one or more sensor nodes, allocated from a fusion center. The one or more sensor nodes determine whether to operate at a specific time. At least one sensor node that has determined to operate among the one or more sensor nodes multiplies the Gaussian codes by a transmission signal and transmits the multiplied signal to the fusion center. | 2013-06-13 |
20130148714 | ENCODING IN TWO CHROMINANCE DIRECTIONS - The present disclosure relates generally signal processing. One claim recites an apparatus comprising: memory for storing a color video signal comprising first data and second data; and a processor. The processor is programmed for: modifying first color information and second color information of the first data by encoding a signal in the first color information such that the signal includes a first signal polarity, and encoding the signal in the second color information such that signal includes a second signal polarity that is inversely related to the first signal polarity, and modifying first color information and second color information of the second data by encoding the signal in the first color information such that signal includes the second signal polarity, and encoding the signal in the second color information such that the signal includes the first signal polarity. Of course, different combinations and claims are provided too. | 2013-06-13 |
