摘要： Methods, apparatus and software for implementing enhanced data center congestion management for non-TCP traffic. Non-congested transmit latencies are determined for transmission of packets or Ethernet frames along paths between source and destination end-end-nodes when congestion along the paths is not present or minimal. Transmit latencies are similarly measured along the same source-destination paths during ongoing operations during which traffic congestion may vary. Based on whether a difference between the transmit latency for a packet or frame and the non-congested transmit latency for the path exceeds a threshold, the path is marked as congested or not congested. A rate at which the non-TCP packets are transmitted along the path is then managed as function of a rate at which the path is marked as congested. In one implementation, non-TCP traffic is managed by mimicking a Data Center TCP technique, under which the congestion marking status of the path is substituted as an input to a DCTP algorithm in place of the normally-used ECN-Echo flag input. The congestion window output by the DCTCP algorithm is then used to manage the rate at which non-TCP packets to be forwarded via the path are transmitted from a source end-node.

摘要： A flexible arrangement allows a single arrangement of Ethernet channel adapter (ECA) hardware functions to appear as needed to conform to various operating system deployment models. A PCI interface presents a logical model of virtual devices appropriate to the relevant operating system. Mapping parameters and values are associated with the packet streams to allow the packet streams to be properly processed according to the presented logical model and needed operations. Mapping occurs at both the host side and at the network side to allow the multiple operations of the ECA to be performed while still allowing proper delivery at each interface.

摘要： Apparatus, method and system for supporting Remote Direct Memory Access (RDMA) Read V2 Request and Response messages using the Internet Wide Area RDMA Protocol (iWARP). iWARP logic in an RDMA Network Interface Controller (RNIC) is configured to generate a new RDMA Read V2 Request message and generate a new RDMA Read V2 Response message in response to a received RDMA Read V2 Request message, and send the messages to an RDMA remote peer using iWARP implemented over an Ethernet network. The iWARP logic is further configured to process RDMA Read V2 Response messages received from the RDMA remote peer, and to write data contained in the messages to appropriate locations using DMA transfers from buffers on the RNIC into system memory. In addition, the new semantics removes the need for extra operations to grant and revoke remote access rights.

摘要： A computer system such as a server pipelines RNIC interface (RI) management/control operations such as memory registration operations to hide from network applications the latency in performing RDMA work requests caused in part by delays in processing the memory registration operations and the time required to execute the registration operations themselves. A separate QP-like structure, called a control QP (CQP), interfaces with a control processor (CP) to form a control path pipeline, separate from the transaction pipeline, which is designated to handle all control path traffic associated with the processing of RI control operations. This includes memory registration operations (MR OPs), as well as the creation and destruction of traditional QPs for processing RDMA transactions. Once the MR OP has been queued in the control path pipeline of the adapter, a pending bit is set which is associated with the MR OP. Processing of an RDMA work request in the transaction pipeline that has engendered the enqueued MR OP is permitted to proceed as if the processing of the MR OP has already been completed. If the work request gets ahead of the MR OP, the associated pending bit being set will notify the adapter's work request transaction pipeline to stall (and possibly reschedule) completion of the work request until the processing of the MR OP for that memory region is complete. When the memory registration process for the memory region is complete, the associated pending bit is reset and the adapter transaction pipeline is permitted to continue processing the work request using the newly registered memory region.
