摘要： Disclosed are various embodiments for frame preemption and fragmentation at the media access control (MAC) sublayer of the link layer or the MAC merge sublayer of the link layer. Traffic classes may be organized into preemptive traffic classes and non-preemptive traffic classes. Preemptable frames may be fragmented when a preemptive frame is to be transmitted. The fragmentation may be indicated through modification of the value of cyclic redundancy check (CRC) field in a predetermined way, through addition of a fragmentation trailer, and/or through other approaches.

摘要： A method of generating a CRC for a composite sub-message based on a CRC generating polynomial having at least two factors. The composite sub-message includes sub-message data and a number, n, of trailing zeros. The method includes generating a first remainder based on the sub-message data and a first factor of the CRC generating polynomial. A second remainder is generated based on the sub-message data and a second factor of the CRC generating polynomial. The CRC for the composite sub-message is generated based on adjusted versions of the first and the second remainders.

摘要： A method for coding a packet of information words into frames for transmission, includes receiving blocks of input data, including control words and the packet of information words. When the block consists exclusively of information words, a master transition having a first sense is scrambled and appended to the block to form one of the frames. When the block does not consist exclusively of information words: the block is condensed to accommodate a TYPE word; a TYPE word having a value that indicates a structural property of the block is generated and inserted into the block; and a master transition having a second sense, opposite to the first sense, is scrambled and appended to the block to form one of the frames.

摘要： Methods for adjusting an m-bit CRC of sub-messages are provided. Such adjustments enable the computation of the CRC of a message by XORing the partial or incremental CRCs of composite sub-messages corresponding to the sub-messages. In a first method, the contents of an m-bit memory location are field squared and stepped to the next state as determined by the Galois field generated by the CRC generating polynomial to adjust the m-bit CRC. In a second method, the partial m-bit CRC of a sub-message is calculated according to CRC generating polynomial, P(x). A variable Y is calculated using a lookup table, where Y=xn modulo P(x). The partial m-bit CRC and Y are multiplied together and divided by P(x). The remainder of the division forms the adjusted m-bit CRC.

摘要： The present invention provides an improved shared memory switching method in which a guaranteed minimum number of buffers per output port is reserved for each input port. The shared memory may also be optionally divided into reserved and unreserved buffers, with the guaranteed minimum number of buffers being provided from the reserved buffers. The unreserved buffers are available to any port and will handle burst communications and other events that cause a given input port's allocation of reserved buffers to be exhausted. So that bursts are also handled fairly among input ports, additional optional features of the present invention include limiting the number of unreserved buffers that may be consumed by a single input port. For fairness among output ports, method also preferably fairly allocates unreserved buffers among the output ports.
摘要翻译：本发明提供一种改进的共享存储器切换方法，其中为每个输入端口保留每个输出端口的保证的最小数量的缓冲器。共享存储器还可以可选地分为保留缓冲器和未保留缓冲器，保留的最小数量的缓冲器从保留的缓冲器提供。未预留的缓冲区可用于任何端口，并将处理突发通信和导致给定输入端口分配预留缓冲区的其他事件。因此，在输入端口之间也公平地进行突发处理，本发明的附加可选特征包括限制单个输入端口可能消耗的未预留缓冲器的数量。为了输出端口之间的公平性，方法还优选地在输出端口之间公平地分配未预留的缓冲器。

摘要： A method and apparatus is provided that solves the problem of data overrun and underrun, for example in a system that exchanges data using the Gigabit Ethernet protocol. A single 8-bit data path is provided as output and the main protocol state machines are kept running in the clock domain of the rest of the circuit, after an elasticity FIFO, so that no additional synchronization is necessary. The invention makes no demands upon the receive clock other than those specified in the relevant standard for duty cycle and accuracy. The invention correctly combines the two effective data streams back into a single data stream, only modifying the FIFO when it is acceptable to do so, and in a way that does not corrupt data packets passing through the FIFO. By providing a minimal set of logic running in the receive clock domain, it is possible to simplify the design of the main protocol state machines. Only a very small portion of the design must be aware of the dual-clock nature of the physical interface. In addition, because all key state machines are no longer in the receive clock domain, any state information or registers are available even if the receive clocks are not running correctly, as is the case with a removable transceiver design.
摘要翻译：提供了一种解决数据超限和欠载问题的方法和装置，例如在使用千兆以太网协议交换数据的系统中。提供单个8位数据路径作为输出，并且主协议状态机在弹性FIFO之后保持在电路的其余部分的时钟域中运行，使得不需要额外的同步。本发明不要求在相关标准中规定的占空比和精度以外的接收时钟。本发明将两个有效数据流正确地组合成单个数据流，只有在可接受时才修改FIFO，并且以不破坏通过FIFO的数据分组的方式。通过提供在接收时钟域中运行的最小逻辑集合，可以简化主协议状态机的设计。只有很小一部分设计必须了解物理接口的双时钟性质。另外，由于所有关键状态机不再在接收时钟域，所以即使接收时钟运行不正确，任何状态信息或寄存器都可用，如可拆卸收发器设计的情况。

摘要： A system and method for unique identifier exchange during auto-negotiation. Wired networks can include non-conformant bridges and/or repeaters that can erroneously forward link protocol frames such as LLDP. These present a problem for higher layer protocols that attempt to manage properties of the link. The unique identifiers exchanged during auto-negotiation can be passed up to higher layers for an integrity check of unique identifiers exchanged using higher layer protocols.

摘要： A system for computing a CRC value includes at least one memory for storing a data message, a current CRC value, and a plurality of lookup tables. The data message includes a plurality of words, with each word including a plurality of bytes. Each of the lookup tables stores a plurality of multi-byte CRC values. The system includes a processor for processing the message a word at a time. The processor is configured to update the current CRC value during processing each word based on an XOR of the word and the current CRC value, and based on a multi-byte CRC value retrieved from each one of the lookup tables.
