摘要： A mechanism for performing remote direct memory access (RDMA) operations between a first server and a second server. The apparatus includes a packet parser and a protocol engine. The packet parser processes a TCP segment within an arriving network frame, where the packet parser performs one or more speculative CRC checks according to an upper layer protocol (ULP), and where the one or more speculative CRC checks are performed concurrent with arrival of the network frame. The protocol engine is coupled to the packet parser. The protocol engine receives results of the one or more speculative CRC checks, and selectively employs the results for validation of a framed protocol data unit (FPDU) according to the ULP.

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 method and system for controlling access to computer resources by multiple software components is described. A locker manager is provided, which is adapted to manage access to shared computer resources by independent software components. If a particular hardware resource is not currently being used and is available, the locker manager grants a particular software component access to the particular computer resource and locks access thereto, wherein none of the other software components can access the particular computer resource until the particular software component has finished accessing the particular computer resource.

摘要： Methods, apparatus and systems for reducing usage of Doorbell Rings in connection with RDMA operations. A portion of system memory is employed as a Memory-Mapped Input/Output (MMIO) address space configured to be accessed via a hardware networking device. A Send Queue (SQ) is stored in MMIO and is used to facilitate processing of Work Requests (WRs) that are written to SQ entries by software and read from the SQ via the hardware networking device. The software and logic in the hardware networking device employ pointers identifying locations in the SQ corresponding to a next write WR entry slot and last read WR entry slot that are implemented to enable WRs to be written to and read from the SQ during ongoing operations under which the SQ is not emptied such that doorbell rings to notify the hardware networking device that new WRs have been written to the SQ are not required.
