摘要： A port for connecting a node to a network loop is disclosed. The port includes a detect element, a frame termination generator, a buffer data generator, a switching element, and a control element. The detect element monitors data from the node and sets an error flag when invalid data is received at the port. The frame termination generator generates frame termination primitives. The buffer data generator generates buffer data. The switching element has a control input, an output, and a plurality of data inputs. Each of an output of the node, the upstream node, the frame termination generator, and the buffer data generator is connected to a corresponding data input. The control element is connected to the detect element and the control input of the switching element. The control element selects, according to the error flag, one of the data inputs of the switching element. The selection connects to the output of the switching element to be output by the port to a downstream node. The control element terminates a current data frame by selecting the data input corresponding to the frame termination generator when the error flag indicates that the current data frame includes invalid data.

摘要： A method and apparatus for processing and transferring frames of data in a computer data link that maps incoming frames to a specific buffer ring in host memory based on routing control and type fields in each frame. More particularly, a Fibre Channel link port contains receiver routing code (RRCode) registers that allow host software to set up routing control (R.sub.-- CTL) match and mask fields, and TYPE match and mask fields. The link port uses these registers to match and mask against corresponding R.sub.-- CTL/TYPE fields in a received frame to determine which of several R.sub.-- CTL/TYPE host memory buffer rings should be used to store the received frame. The link port places a code (RRCode) in a start of frame (SOF) status word associated with a frame. The RRCode indicates a specific R.sub.-- CTL/TYPE host memory buffer ring, or indicates that no match was found or that multiple matches were found. A protocol engine reads the RRCode field in the SOF status word of the received frame, and queues a direct memory access (DMA) operation to an appropriate R.sub.-- CTL/TYPE buffer ring. The host may then process the contents of the indicated buffer ring. Since the buffer rings are "pre-sorted" as to frame type, the host may more efficiently respond to incoming frames.
摘要翻译：一种在计算机数据链路中处理和传送数据帧的方法和装置，该计算机数据链路基于每个帧中的路由控制和类型字段将输入帧映射到主机存储器中的特定缓冲环。更具体地，光纤通道链路端口包含允许主机软件建立路由控制（R-CTL）匹配和掩码字段以及TYPE匹配和掩码字段的接收机路由代码（RRCode）寄存器。链路端口使用这些寄存器来匹配和掩蔽接收到的帧中的相应的R-CTL / TYPE字段，以确定应该使用几个R-CTL / TYPE主机内存缓冲区中的哪一个来存储接收到的帧。链路端口将代码（RRCode）放置在与帧相关联的帧（SOF）状态字的起始处。 RRCode指示特定的R-CTL / TYPE主机内存缓冲区环，或表示未找到匹配或找到多个匹配。协议引擎读取接收到的帧的SOF状态字中的RRCode字段，并将直接存储器访问（DMA）操作排队到适当的R-CTL / TYPE缓冲环。然后，主机可以处理指示的缓冲环的内容。由于缓冲环针对帧类型进行“预排序”，所以主机可以更有效地响应输入帧。

摘要： A loop network hub port with an automatic bypass feature. The automatic bypass feature causes the hub port to enter a bypass mode upon detection of a specified loop failure initialization sequence from a node port attached to the hub port. The hub port does not propagate loop failure initialization data generated by the attached node port upon the failure of a data channel from the hub port to the node port. The hub port replaces loop failure initialization data received from the node port with buffer data and conceals the node port failure from the remainder of the loop. Upon detection of the loop failure initialization sequence received from the attached node port, the hub port enters a bypass mode and maintains that bypass mode until a recovery sequence is received from the node port. At that point, the hub port reinserts the node port into the loop.

摘要： Methods and apparatus for implementing a technique for inserting and removing a node in a network loop. In a preferred implementation, a hub port includes a detect element which monitors data from the node and from an upstream node. The detect element sets a first flag when a primitive is received at the port, and sets a second flag when a primitive which is a frame termination primitive is received at the port. A frame termination generator generates frame termination primitives and a buffer data generator generates buffer data. A switching element has a control input, an output, and a plurality of data inputs. One data input is connected to each of an output of the node, the upstream node, the frame termination generator, and the buffer data generator. A control element is connected to the detect element and the control input of the switching element. The control element selects, according to the first flag and the second flag, one of the data inputs of the switching element to connect to the output of the switching element to be output by the port to a downstream node.

摘要： Methods and apparatus for implementing a technique for determining a data rate of a serial bitstream using pattern recognition and for matching a clock speed of a deserializer to that data rate. In one implementation, a port for connecting a network device to a network includes a data input for receiving a bitstream from a network, where the bitstream has a data rate; a deserializer connected to the data input, where the deserializer deserializes the bitstream received via the data input, generating data characters; and a network device connected to the deserializer, where the network device receives data characters from the deserializer and determines the data rate of the bitstream by recognizing patterns in the data characters generated by the deserializer. In another implementation, a node port also sets a clock speed of the deserializer to match the data rate of the bitstream.

摘要： A hub port in a hub which preferably eliminates the transfer of jitter in the signal transmitted to an attached node port. In one implementation, jitter transfer is preferably eliminated by transmitting data to an attached node port using a local clock internal to the hub rather than a clock signal recovered from the datastream. The hub port includes smoothing circuits to synchronize data received from the attached node port to the local clock.

摘要： A FIFO memory receives data transfer requests before data is stored in the FIFO memory. Multiple concurrent data transfers, delivered to the FIFO memory as interleaved multiple concurrent transactions, can be accommodated by the FIFO memory (i.e., multiplexing between different sources that transmit in distributed bursts). The transfer length requirements associated with the ongoing data transfers are tracked, along with the total available space in the FIFO memory. A programmable buffer zone also can be included in the FIFO memory for additional overflow protection and/or to enable dynamic sizing of FIFO depth.

摘要： A frame receive queue may perform disassembly and validation operations on frames received by a node in a Fiber Channel network. The frame receive queue may store information used for later processing of the frames, e.g., header data and the first eight payload words, in an on-chip memory for fast processor access. The payload data for the frames may be stored in a larger, external memory.
