摘要： A media independent interface for interconnecting an integrated repeater front-end with one or more integrated interface devices, each having several physical layer devices for operation in conformance with IEEE 802.3u. The media independent interface, in a repeater implementation, shares transmit and receive data channels, and provides for dedicated control signals, thereby multiplexing shared channels across all of the physical layer devices in the integrated interface device.

摘要： A network switch having a shared memory architecture for storing data frames has a set of programmable thresholds that specify when flow control should be initiated on a selected network port. The network switch includes a queue for storing free frame pointers, each specifying available memory locations in an external memory for storing data frames received from a network station. The network switch takes a frame pointer from a free buffer queue for each received data frame, and stores the received data frame in the location in external memory specified by the frame pointer while a decision making engine within the switch determines the appropriate destination ports. Flow control is initiated on a half-duplex network port by transmitting a phantom packet to a transmitting network station if the output buffer of a destination port exceeds a programmed high threshold, or if the output buffer of the destination port exceeds a low programmed threshold and the queue of free frame pointers falls below a low programmable threshold. The switch thus provides flexibility in providing selective collisions with transmitting stations to minimize the possibility of network congestion without wasting network bandwidth with unnecessary collisions.
摘要翻译：具有用于存储数据帧的共享存储器架构的网络交换机具有一组可编程阈值，其指定何时应当在所选择的网络端口上启动流量控制。网络交换机包括用于存储空闲帧指针的队列，每个指定用于存储从网络站接收的数据帧的外部存储器中的可用存储器位置。网络交换机从每个接收到的数据帧的空闲缓冲器队列中获取帧指针，并且将接收到的数据帧存储在由帧指针指定的外部存储器中的位置，同时交换机内的决策引擎确定适当的目的地端口。如果目的地端口的输出缓冲区超过编程的高阈值，或者目的端口的输出缓冲区超过低编程阈值，则通过将虚拟分组发送到发射网络站，在半双工网络端口上启动流量控制，空闲帧指针的队列低于低可编程阈值。因此，交换机提供灵活性，以提供与发射站的选择性冲突，以最小化网络拥塞的可能性，而不浪费网络带宽与不必要的冲突。

摘要： A method and arrangement for transmitting multiple copies of a frame from a network switch in a packet switched network stores a single copy of the frame received at the switch into external memory. The frame is stored at a location in memory pointed to by a frame pointer. In queuing multiple transmissions of the stored frame in the switch, the frame pointer, and not the frame itself, is replicated and queued for transmission in the network switch.

摘要： A flow control enabled Ethernet switch that applies backpressure to input ports that attempt to transmit a data packet to a busy destination port. The backpressure is a phantom packet that activates to abort transmission of the data packet. When the destination port is available, the phantom packets control retransmission, permitting standard retransmission of the data packet. The switch may include prioritization mechanisms to use when awarding priority to a port having backpressure applied.

摘要： A method is provided for use with an Ethernet Media Access Controller (MAC) and a look-up memory external to the MAC, the method determines whether to accept or to reject an Ethernet packet which is decoded by the MAC into a serial data (SRD) signal stream and a serial data clock (SRDCLK) signal, the method comprises the steps of: converting the SRD signal stream into byte frames and loading the frames into a receive FIFO of the MAC; while the receive FIFO is being loaded, producing by the MAC, a boundary delimiter (BD) signal stream which delimits the frame boundary of each byte frame; while the receive FIFO is being loaded, providing the SRD signal stream, the SRDCLK signal and the BD signal stream from the MAC to the look-up memory; while the receive FIFO is being loaded, determining whether a prescribed field in the packet matches information stored in the look-up memory; while the receive FIFO is being loaded, informing the MAC by the look-up memory whether a match has been detected.
