20080285460 | METHOD AND SYSTEM FOR FAULT RESILIENCE IN NETWORKS WITH AUDIO/VIDEO BRIDGING AWARE SHORTEST PATH BRIDGING - Aspects of a method and system for fault resilience in Audio/Video Bridging (AVB) aware Shortest Path Bridging (SPB) networks are provided. In this regard, a path cost, which may be based at least on AVB compatibility, may be determined for each network path discovered between a first network node and a second network node. Additionally, a plurality of network paths may be selected based on the determined path cost, and a plurality of network connections may be established over the selected plurality of network paths. Also, a plurality of data streams may be transmitted and/or received via the established network connections, wherein at least one of data streams comprises data that is redundant to a first data stream. Furthermore, a primary data stream may be conveyed via a first network connection and one or more redundant data streams may be conveyed via a second network connection. | 11-20-2008 |
20080288702 | METHOD AND SYSTEM FOR DOCKING A LAPTOP WITH ETHERNET A/V BRIDGING TO GUARANTEE SERVICES - Methods and systems for docking a laptop with Ethernet A/V bridging to guarantee services are disclosed and may include interfacing a portable computing device with a docking station using an Ethernet interface, and utilizing audio/video (AV) bridging for communicating data between the portable computing device and one or more devices coupled to the docking station. AV bridging may be utilized based on latency requirements of the data communication. The interfacing may include directly coupling an Ethernet port of the docking station to an Ethernet port of the portable computing device. Alternatively, the interfacing may include coupling an Ethernet port of the docking station to an Ethernet port of the portable computing device via an Ethernet cable. The portable computing device may be powered via the Ethernet interface, and may utilize power over Ethernet protocol. The docking station may include a passive or active docking station. | 11-20-2008 |
20080288704 | METHOD AND SYSTEM FOR UNIVERSAL SERIAL BUS (USB) OVER A/V BRIDGING AND A/V BRIDGING EXTENSIONS - Aspects of a system for universal serial bus (USB) over ANV bridging and ANV bridging extensions may include a LAN subsystem that enables reception of signals from a peripheral device coupled to a computing device via a USB interface. The LAN subsystem may enable the generation of payload data based on the received signals. The LAN subsystem may enable transmission of the generated payload data via a network based on a traffic class designation. The generated payload data may be encapsulated within an outgoing PDU, which may include an Ethernet frame and/or an IP packet. The outgoing encapsulating PDU may contain the traffic class designation. The LAN subsystem may also generate a time stamp for the encapsulating PDU. The LAN subsystem may enable indication that the outgoing encapsulating PDU encapsulates the generated payload data based on one or more data type identifiers, which include an EtherType and an EtherTypeSubType. | 11-20-2008 |
20100312941 | NETWORK INTERFACE DEVICE WITH FLOW-ORIENTED BUS INTERFACE - A network interface device includes a bus interface that communicates over a bus with a host processor and memory, and a network interface that sends and receive data packets carrying data over a packet network. A protocol processor conveys the data between the network interface and the memory via the bus interface while performing protocol offload processing on the data packets in accordance with multiple different application flows. The bus interface queues the data for transmission over the bus in a plurality of queues that are respectively assigned to the different application flows, and transmits the data over the bus according to the queues. | 12-09-2010 |
20110038381 | METHOD AND SYSTEM FOR FAULT RESILIENCE IN NETWORKS WITH AUDIO/VIDEO BRIDGING AWARE SHORTEST PATH BRIDGING - A first network device may select a plurality of network paths for establishing a plurality of network connections to a second network device. The selection may be based on support of IEEE Audio Video Bridging (AVB) protocols. The first network device may establish at least one of the plurality of connections over each of the selected network paths. The first network device may concurrently transmit and/or receive a plurality of data streams via the established plurality of network connections. At least a second one of the plurality of data streams may comprise data that is redundant to a first one of the plurality of data streams. One of the plurality of network connections may be selected for conveying a primary data stream based on determined path costs of the plurality of network paths, where non-AVB links may be assigned higher path costs than AVB link. | 02-17-2011 |
20140328593 | Synchronization and Control Using Out-of-Band Channels in Passive Optical Network-Based Systems - Systems and methods are provided to use of out-of-band (OOB) channels for the transport of network-synchronization signals and network control information. These OOB channels transport synchronization and control channels over low-frequency bands outside of the frequency bands used for the data channels. Locating expensive network-synchronization functions in the optical network unit (ONU) and sharing the derived synchronization signals among multiple downstream customer premises equipment (CPE) devices results in cost savings and provides a means for maintaining a continuous, end-to-end synchronization reference, even during periods when the data channels on the copper network segment are in an energy-efficiency mode (e.g., a low-power and/or sleep mode). | 11-06-2014 |
20150131643 | Radio Over Ethernet Mapper Physical Layer Device (PHY) - A mapper PHY is disclosed that performs a protocol conversion of an input data stream that is formatted according to a first wired communication protocol to provide an output data stream that is formatted according to a second wired communication protocol. The mapper PHY can be synchronized to a common reference clock or clocking source to ensure that data streams provided by multiple mapper PHYs are sufficiently aligned to satisfy frame timing alignment accuracy requirements of a wireless communication protocol. | 05-14-2015 |
20150236785 | CPRI FRAMELETS - A system for providing a reduced common public radio interface (CPRI) framelet link includes one or more cellular towers, each cellular tower including one or more cellular antennas and coupled to a first short CPRI fiber link.
