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 computer-implemented method for protecting a memory is provided. The method includes responsive to a direct memory access (DMA) request received from a consumer for a transaction of data from an IO device to the memory, the request including an IO command and a capability (CAP), generating a cryptographically signed capability (CAPB), forming a credential from CAP and CAPB, appending the credential to the IO command, configuring the IO device according to the credential and the IO command, transmitting the data from the IO device to the memory and prior to allowing execution of the DMA, authenticating that the credential is valid, further includes regenerating CAPB from a key available to an authenticating entity and from the CAP (included in CAPB) and verifying that the memory region information described in the cryptographically signed capability is the same as the requested region that was originally created, and that the cryptographically signed capability encompasses the IO command.

摘要： A method and system for memory address translation and pinning are provided. The method includes attaching a memory address space identifier to a direct memory access (DMA) request, the DMA request is sent by a consumer and using a virtual address in a given address space. The method further includes looking up for the memory address space identifier to find a translation of the virtual address in the given address space used in the DMA request to a physical page frame. Provided that the physical page frame is found, pinning the physical page frame as long as the DMA request is in progress to prevent an unmapping operation of said virtual address in said given address space, and completing the DMA request, wherein the steps of attaching, looking up and pinning are centrally controlled by a host gateway.
