摘要： An interface located on a network switch transmits header information to an external device that makes data forwarding decisions. The interface receives and transmits header information that includes the source and destination address of the data. The external device generates data forwarding information and transmits the information back to the switch via the interface device. The network switch uses the information obtained via the interface and forwards the data packets to the appropriate destination.

摘要： A network having a shared memory architecture for storing data frames has a set of programmable thresholds that specify when flow control should be initiated on full-duplex network ports. The network switch includes a queue for storing free frame pointers that specify 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 based on the number of available frame pointers by transmitting a PAUSE frame having a selected PAUSE interval to a transmitting network station. Specifically, a full-duplex port will output a PAUSE frame having a short, medium, or long programmed pause interval if the free buffer pool of available frame pointers falls below a high, medium, or low programmable threshold, respectively. The switch thus provides flexibility in generating variable-length PAUSE control frames to minimize wasting network bandwidth.

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 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： Management data is supplied to a management agent by a network switch by generating management packets having at least a portion of a received data packet, and management information specifying receive status and network switch response characteristics to the corresponding received data packet. The network switch includes a plurality of network ports, including network traffic ports and one management port for synthesizing the management frame. A network traffic port receiving a data packet generates receive status data specifying the reception status of the received data packet, including the presence of cyclic redundancy check (CRC) errors, frame alignment errors, and receive buffer overflow conditions. The received data packet and received status data are stored in a buffer memory, while switching logic generates port vectors specifying destination output ports and switching logic data specifying the switching logic response to the received data packet. The management port selectively compiles the received status data, the switching logic data, and at least a portion of the received data frame into a management frame, and outputs the synthesized management frame to a management agent according to a media access control (MAC) layer protocol. The generation of management frame provides detailed management information corresponding to characteristics of the received data packet and the corresponding network switch response, independent of the timing at which the data packet was received by the network switch.

摘要： A method and arrangement for queuing data in a prioritized manner has a queue with a single queue write side in which data entries are input to the queue. The queue also has a plurality of queue read sides, with each read side having a different priority level. An entry exiting from the queue write side is examined to determine the priority level of the entry, and then placed into the queue read side with the matching priority level as the entry. The queue read sides form the output of the queue, and are polled and emptied so that the higher priority queues are emptied completely before emptying lower priority queues.
