摘要： A method and apparatus is disclosed for temporarily deferring transmission of frames to a destination in a data switch. When a request for transmission of a frame to the destination port is received, the congestion status of that destination is determined. If the destination is congested, the frame is stored in a deferred queue. When the status of a destination changes from congested to non-congested, the deferred queue is examined to see if any deferred frames can now be forwarded to their destination. While examining the deferred queue, incoming frames are placed on a backup queue. When the deferred queue is fully analyzed, the backup queue is emptied by either sending those frames to their destination or storing the frames in the deferred queue. While examining the deferred queue, the congested states of the destinations are not allowed to change from congested to non-congested.

摘要： A switch segments variable length frames into cells for transmission over a cell-based switch fabric and handles rate differences between the input data rate and the switch fabric data rate. The fabric handles multiple cell packets by maintaining a switch path until a certain number of cells are transmitted as indicated in a length field in the first data cell. The first cell contains a full data payload, and a length field value sufficient to handle a maximum length frame. Subsequent cells can contain less than a full data payload, with the number of valid bytes in the cell being indicated in the length field. The last cell used to segment the frame contains an end of frame indicator. The indicator signals the destination port side of the switch to terminate the packet path in the switch fabric prematurely—before the number of cells indicated in the first data cell.
摘要翻译：交换机将可变长度的帧分段成小区，用于通过基于小区的交换结构进行传输，并处理输入数据速率和交换矩阵数据速率之间的速率差异。该结构通过维持交换路径来处理多个信元分组，直到如第一数据信元中的长度字段所示传送一定数量的信元。第一个单元格包含一个完整的数据有效载荷，以及足以处理最大长度帧的长度字段值。后续单元格可以包含小于一个完整的数据有效负载，单元格中的有效字节数在长度字段中指示。用于分割帧的最后一个单元格包含帧指示符的结尾。该指示符向交换机的目的地端口侧发信号通知交换结构中的分组路径提前在第一个数据信元中指示的小区数。
