摘要： A routing system utilizes a layer 2 switch interconnecting several routers to intelligently forward multicast packets throughout an internet exchange carrying multicast content. The layer 2 switch performs protocol snooping to extract a lookup key that is based on network layer protocol information. The lookup key is uniquely formulated to support either shared or explicit source distribution trees. The lookup key is used to query a forwarding memory that returns an outgoing port index. The outgoing port index points to one or more outgoing ports that are eligible to receive the multicast packet. The outgoing ports are also connected to the neighboring device(s) that are designated to receive the multicast packet. The routing system also supports real time maintenance and updating of the forwarding memory based on the periodic exchange of control messages. The routing system is configured to support PIM routers operating in PIM SM or PIM SSM modes. However, the routing system can also support other multicast protocols and/or standards.

摘要： A gain control system for a gain stage of a wireless communication system includes a gain control module and a mode selection module. The gain control module is operable in automatic gain control (AGC) and manual gain control (MGC) modes. The mode selection module checks the presence of first user-data in the first sub-frame based on a received signal strength indication (RSSI) value and/or a decibel amplitude level relative to full scale (dBFS) value, the presence of second user-data in a second sub-frame subsequent to the first sub-frame based on an advance information, calculates an estimated signal power level, and configures the gain control module in one of the AGC and MGC modes. Based on the mode, the gain control module provides a gain value to the gain stage.

摘要： Solutions are provided that allow a network device to apply flow control on the MAC layer while taking into account the priority of the frame of traffic. This may be accomplished by generating a frame indicating that traffic flow should be paused, while utilizing a new opcode value, or alternatively by utilizing a new type/length value (possibly combined with a new opcode value). A receiving device may then examine the fields of the frame to determine whether it should use priority-based pausing, and then examine other fields to determine which priority-levels to pause and for how long. This allows for improved efficiency in flow control on the MAC layer.
摘要翻译：提供的解决方案允许网络设备在考虑到流量帧的优先级的情况下对MAC层应用流量控制。这可以通过生成指示业务流应该被暂停，同时利用新的操作码值，或者通过利用新的类型/长度值（可能与新的操作码值组合）来实现。然后，接收设备可以检查帧的字段以确定它是否应该使用基于优先级的暂停，然后检查其他字段以确定要暂停的优先级等级以及多长时间。这样可以提高MAC层的流量控制效率。

摘要： The present disclosure includes an integrated full-duplex transceiver, which may be implemented on a single substrate or die. A single substrate may in turn, comprise, an I/O port configured for full-duplex operation, a transmit portion and a receive portion, a first mixer for up-converting a transmit signal, a second mixer for down-converting a receive signal, a first independently tunable local oscillator that drives the first mixer, and a second independently tunable local oscillator that drives the second mixer. The first independently tunable oscillator may facilitate up-conversion of a transmit IF signal, while a second independently tunable oscillator may facilitate down-conversion of a receive RF signal.

摘要： The present invention provides a method and system of providing minimization drive test (MDT) measurement information to a base station in a wireless communication network. In one embodiment, a method includes indicating availability of MDT measurement information logged by user equipment to a base station in a wireless network environment. The method further includes receiving an information request message to transfer the MDT measurement information in response to the indication. The method includes transmitting an information response message including at least a portion of the MDT measurement information to the base station, where the information response message indicates whether any portion of MDT measurement information is leftover with the user equipment. The method then includes repeating the above steps of receiving and transmitting till the entire MDT measurement information is transferred to the base station.
