摘要： A Fiber Channel switch is presented that tracks the congestion status of destination ports in an XOFF mask at each input. A mapping is maintained between virtual channels on an ISL and the destination ports to allow changes in the XOFF mask to trigger a primitive to an upstream port that provides virtual channel flow control. The XOFF mask is also used to avoid sending frames to a congested port. Instead, these frames are stored on a single deferred queue and later processed in a manner designed to maintain frame ordering. A routing system is provided that applies multiple routing rules in parallel to perform line speed routing. The preferred switch fabric is cell based, with techniques used to manage path maintenance for variable length frames and to adapt to varying transmission rates in the system. Finally, the switch allows data and microprocessor communication to share the same crossbar network.
摘要翻译：提供了一个光纤通道交换机，可以在每个输入端跟踪XOFF掩码中目标端口的拥塞状态。在ISL的虚拟通道和目标端口之间维护映射，以允许XOFF掩码中的更改触发提供虚拟通道流控制的上游端口的基元。 XOFF掩码也用于避免向拥塞的端口发送帧。相反，这些帧被存储在单个延迟队列中，并且稍后以设计为维持帧排序的方式进行处理。提供了并行应用多个路由规则以执行线速度路由的路由系统。优选的交换结构是基于小区的，具有用于管理可变长度帧的路径维护并适应系统中变化的传输速率的技术。最后，交换机允许数据和微处理器通信共享相同的交叉网络。

摘要： A method for providing an early packet termination such that prior to the complete transmission of the number of cells specified in the first cell of a packet, a crossbar connection is released. The act of releasing the connection is triggered on recognition of an End of Packet bit (EOP) set in any cell of the stream. The feature can be enabled, for example, by a specific act of setting a register bit, connecting a pin to Vcc or ground or some other intentional act. The feature will default to the inactive state upon reset.

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： 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.
摘要翻译：公开了一种用于在数据交换机中暂时推迟到目的地传送帧的方法和装置。当接收到向目的地端口发送帧的请求时，确定该目的地的拥塞状态。如果目的地拥塞，则将帧存储在延迟队列中。当目的地状态从拥塞状态改变为非拥塞状态时，会检查延迟队列，以查看是否有任何延迟帧现在可以转发到其目的地。在检查延迟队列时，传入帧将放置在备份队列中。当延迟队列被完全分析时，通过将这些帧发送到其目的地或将帧存储在延迟队列中，备份队列将被清空。在检查延期队列时，目的地的拥塞状态不允许从拥塞状态改为非拥塞状态。

摘要： A method and apparatus that recognizes a portion of an address that would be unrecognizable to an intended associated switch or device and manipulates the portion of the address to make it recognizable. The apparatus and method manipulates a discontinuous address to provide the appearance to the associated device, switch or peripheral, that the address is continuous. This provides additional address capacity such that a new address is created within the switch itself for routing data within the switch. All or a portion of the switches in network are preassigned a chassis address, and each chassis also has a specific switch address that is different from the preassigned chassis address. An address adaptor provides translation of addresses and mapping within a switch so that in the event of a port failure, affected frames can be redirected from the failed port by employing the described translation and mapping operations.

摘要： A fiber channel backplane configuration is capable of modular expansion, e.g., from 64 ports to 128 ports or 256 ports by a simple operation. The backplane includes connectors that provide permanent and jumper/vertical connections to support 64 user port switch in a single chassis. For a 128 port switch, two 64 port chassis are used. In the 128 port configuration, the connectors are configured to provide permanent and jumper/vertical connections to make intra-chassis and inter-chassis connections between the fabric switch and fabric input/output boards. Using jumper plugs, the jumper connectors provide vertical connections between the fiber input/output boards and fiber switch boards of two chassis. For a 256 port switch configuration, four 64 port chassis assemblies are used. The connectors are configured to provide each switch with permanent, vertical, horizontal, and diagonal connections to the fiber input/output boards of each of the four chassis.

摘要： A device for converting at least four parallel data streams on respective input data lines into one serial data stream on a fiber optic data line. The device includes a first multiplexer for multiplexing at least two of the parallel data streams into a first intermediate output stream and a second multiplexer for multiplexing at least two other of the parallel data streams into a second intermediate output stream. A serializing transmitter is coupled to the first and second multiplexers for serializing the first and second intermediate output streams into the serial data stream. A signal synchronizes the serializing of the first and second intermediate output streams and tags output data in the serial data stream as corresponding to data from each of the respective input data lines. In-band messaging is used to transfer commands and status messages between devices without affecting ongoing data stream communications.
