摘要： An RNIC implementation that performs direct data placement to memory where all segments of a particular connection are aligned, or moves data through reassembly buffers where all segments of a particular connection are non-aligned. The type of connection that cuts-through without accessing the reassembly buffers is referred to as a “Fast” connection because it is highly likely to be aligned, while the other type is referred to as a “Slow” connection. When a consumer establishes a connection, it specifies a connection type. The connection type can change from Fast to Slow and back. The invention reduces memory bandwidth, latency, error recovery using TCP retransmit and provides for a “graceful recovery” from an empty receive queue. The implementation also may conduct CRC validation for a majority of inbound DDP segments in the Fast connection before sending a TCP acknowledgement (Ack) confirming segment reception.
摘要翻译：执行直接数据放置到特定连接的所有段对齐的存储器的RNIC实现，或者通过重组缓冲区移动数据，其中特定连接的所有段都不对齐。在不访问重组缓冲区的情况下，直接连接的类型被称为“快速”连接，因为它很可能被对齐，而另一种类型被称为“慢速”连接。当消费者建立连接时，它指定一个连接类型。连接类型可以从快速变慢到慢。本发明减少了内存带宽，延迟，使用TCP重传的错误恢复，并提供了从空接收队列的“优雅恢复”。在确认段接收之前，实现还可以在Fast连接中的大部分入站DDP段进行CRC校验。

摘要： A novel and useful method of constructing a fast approximation of a dynamic Huffman table from a data sample comprising a subset of data to be compressed. The frequency of incidence of each symbol in the sample is calculated, and the symbols are then allocated to predefined bins based on their frequency of incidence. The bins are then transformed into binary sub-trees, where the leaf nodes of the binary sub-trees comprise the symbols of the bin associated with the binary sub-trees. The binary sub-trees are then combined via nesting, thereby creating a coarse grained binary tree, where all leaves are mapped to a specified number of depths. The coarse grained binary tree is then traversed, thereby yielding a canonical code for each symbol, thereby defining the entries for a dynamic Huffman table.

摘要： A DMA device prefetches descriptors into a descriptor prefetch buffer. The size of descriptor prefetch buffer holds an appropriate number of descriptors for a given latency environment. To support a linked list of descriptors, the DMA engine prefetches descriptors based on the assumption that they are sequential in memory and discards any descriptors that are found to violate this assumption. The DMA engine seeks to keep the descriptor prefetch buffer full by requesting multiple descriptors per transaction whenever possible. The bus engine fetches these descriptors from system memory and writes them to the prefetch buffer. The DMA engine may also use an aggressive prefetch where the bus engine requests the maximum number of descriptors that the buffer will support whenever there is any space in the descriptor prefetch buffer. The DMA device discards any remaining descriptors that cannot be stored.
摘要翻译： DMA设备将描述符预取到描述符预取缓冲区中。描述符预取缓冲区的大小在给定的等待时间环境中保存适当数量的描述符。为了支持描述符的链表，DMA引擎基于它们在存储器中是连续的假设来预取描述符，并丢弃任何被发现违反这个假设的描述符。 DMA引擎寻求通过每个事务请求多个描述符尽可能地保持描述符预取缓冲区已满。总线引擎从系统内存中读取这些描述符，并将它们写入预取缓冲区。 DMA引擎还可以使用积极的预取，其中总线引擎请求缓冲区将在描述符预取缓冲器中存在任何空间时将支持的最大数量的描述符。 DMA设备丢弃任何其他不能存储的描述符。

摘要： A method for implementing parallel TCP (transmission control protocol), the method including dividing a TCP connection state, which is accessible by a TCP sender and a TCP receiver, into a plurality of separate access areas, wherein none of the access areas can be updated by both the sender and the receiver, and accessing one or more of the access areas with the sender and/or receiver to write and/or read data. There is no need for locking between the sender and the receiver.
