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。
