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 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.

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 routing module applies a plurality of routing rules simultaneously to determine routing for a Fibre Channel frame. Each rule independently determines whether the rule applies to the frame as well as a routing result for the frame. The routing result includes a port address, a zoning indicator, and a priority designation that can be used to route the frame over a virtual channel in an interswitch link. A selector chooses between the results returned by the rules. A component receives routing results specifying an ISL group and selects a physical ISL for the frame. An in-band priority determined by the content of the frame header can also be used in place of the priority designation in the routing result.
摘要翻译：路由模块同时应用多个路由规则以确定光纤通道帧的路由。每个规则独立地确定该规则是否适用于该帧以及该帧的路由结果。路由结果包括端口地址，分区指示符和可用于在帧间交换链路中的虚拟信道上路由帧的优先级指定。选择器在规则返回的结果之间进行选择。组件接收指定ISL组的路由结果，并为该帧选择一个物理ISL。由帧头的内容确定的带内优先级也可以用于路由结果中的优先级指定。
