摘要： A method for communication includes configuring a network node having at least first and second line cards, the line cards having respective ports, to operate as a distributed media access control (MAC) bridge in a Layer 2 network. Each of the line cards has a respective forwarding database (FDB). Upon receiving a data packet on a port of the network node from a MAC source address, the data packet is conveyed to at least the first line card for transmission to the MAC destination address. The MAC source address of the data packet is checked against the records in the FDB of the first line card. If the FDB does not contain a record of an association of the MAC source address with the port on which the data packet was received, the record is added to the FDB of the first line card, which sends a message to at least the second line card informing the second line card of the association.

摘要： A network node in a communication network includes a plurality of ports, at least a subset of which is grouped in a link aggregation (LAG) group. The node includes packet processing logic, which is coupled to receive data packets having respective destination addresses that specify forwarding the packets to groups of multiple recipients through at least one of the ports and to process the data packets so as to forward only a single copy of each of the data packets via the output ports in the subset, while distributing forwarded copies of the data packets among the output ports in the subset so as to balance a traffic load within the LAG group.

摘要： A system and method for coordinating data communication especially applicable to inverse multiplex (IMUX) systems. A fixed portion of transmitted data is dedicated to overhead data. During link start-up, receiver synchronization is aided by the transmission of a fixed data pattern in the user data and contrasting data in the overhead data. Changes in IMUX configuration, such as changes in the set of links participating in the IMUX, are mediated via commands that allow fast reconfiguration during start-up or in the event of link failure (“Panic Change”), or continued error-free transmission of data during planned reconfigurations (Sync Change).
摘要翻译：用于协调特别适用于反向多路复用（IMUX）系统的数据通信的系统和方法。传输数据的固定部分专用于开销数据。在链路启动期间，通过在用户数据中传输固定数据模式和开销数据中的对比数据来辅助接收机同步。 IMUX配置中的更改，如参与IMUX的链接集中的变化，是通过允许在启动期间或在链路故障（“紧急更改”）的情况下快速重新配置的命令或继续无差错传输的计划重新配置中的数据（同步更改）。

摘要： A system and method for transmitting data includes one or more transmitters connected to each of at least one bus data line via open-driver bus data line drivers, and one or more receivers. In a preferred embodiment, the devices are interconnected by a parallel interface using a bus architecture having the bus data and carrier-sense (CRS) lines each driven by open-collector or open-drain drivers in a wired-and configuration. Pullup resistors and a common clock signal are also provided. Each device is provided with an interfacing unit which connects the device to the bus, and detects collisions by comparing data transmitted by the device with data received from the bus. The invention is particularly applicable to implementation as a backplane connecting intercommunicating printed wiring boards having interfaces such as the IEEE 802.3 (Ethernet) Media Independent Interface (MII), the interfacing unit serving to emulate the Ethernet PHY.
