摘要： A method, apparatus and computer program product are provided for implementing queue pair connection protection over an interconnect network, such as InfiniBand. A message packet is received for a queue pair (QP) and the QP is checked for an imminent connection failure. Responsive to identifying an imminent connection failure, a special message processing mode is established for the QP. After the special message processing mode is established, packets of the message are received without establishing a message queue entry and without storing packet data.

摘要： A method, apparatus and computer program product are provided for implementing N-way fast failover in a virtualized Ethernet adapter. Requests are posted to queue pairs (QPs) to send and receive Ethernet packets. Each QP stores a designated physical Ethernet port. At the time of a failover, the stored failed designated physical Ethernet port in a QP is changed to a new functional physical Ethernet port. An increased bandwidth is available prior to failover because all ports are used, eliminating the use of any backup, idle ports of prior fast failover arrangements.

摘要： An I/O adapter sharing mechanism in a logically partitioned computer system allows sharing a network I/O adapter between logical partitions in an efficient manner. A first logical partition owns (or controls) the I/O adapter, and a second logical partition desires to use (or share) the I/O adapter. An I/O adapter device driver that includes a hardware interface is provided in the first logical partition. A virtual device driver is provided in the second logical partition that provides a set of functions that is at least partially defined by querying the I/O adapter device driver in the first logical partition. The I/O adapter sharing mechanism includes a transfer mechanism that allows data to be transferred directly from the virtual device driver in the second logical partition to the I/O adapter without passing through the I/O adapter device driver in the first logical partition.

摘要： An apparatus and method for an advanced multiplexing technique to allow a single host to support multiple Internet Protocol (IP) queue pairs with little or no overhead are provided. With the apparatus and method, after a queue pair is created, Internet Protocol filter attributes and values are set up for the queue pair through value added features to the standard InfiniBand “QP Modify” method. The IP filters are used during normal operations to determine which queue pair is associated with an incoming packet. During normal operations, when a channel adapter receives an Internet Protocol (IP) over InfiniBand (IB) packet, it uses one or more of several fields in the packet's transport and/or network header to determine which queue pair shall receive the packet. Thus, the host channel adapter uses the IP filters to route incoming packets to the appropriate queue pair and thereby allow more than one queue pair to be used to support IP.

摘要： A method, apparatus, and program product for balancing communication loads between devices of a network comprises the introduction of a delay by a network device before responding to another network device which is sending an initiation signal for establishing communication between the devices. Based upon communication traffic of the second device, a delay occurs for a predetermined amount of time before the responding network device responds, and the delay is proportional to the amount of traffic handled by the responding device.

摘要： A mechanism that dynamically adjusts the number of packets sent in a train from a node to reflect the rate-of-packets arriving at a node in a network. In the preferred embodiment, the node has a packet controller that determines the optimum number-of-packetsito send in the train. The node also has a timer interval, which is the maximum time-to wait before sending the next train. The packet controller samples the packet arrival-rate and calculates the elapsed time to receive a configurable-constant number-of-packets in a train. This elapsed time is referred to as a sampling interval. The packet controller only calibrates the optimum number-of-packets when the sampling interval changes significantly from the historic sampling-interval. A significant change is a predetermined percentage greater or less than the historic interval-time. When the timer interval expires (referred to as a timeout), the packet controller sets the optimum number-of-packets to be the number-of-packets accumulated prior to the timeout, which lets the packet arrival-rate determine the number of packets that should be trained. Furthermore, timeouts occurring without a corresponding increase in the optimum number-of-packets cause the packet controller to first lower the optimum number-of-packets by a small amount, and then on back-to-back timeouts without a received packet, the packet controller causes more drastic to drops in the optimum number-of-packets down to the current number-of-packets accumulated prior to the timeout. This timeout processing rides out small changes in the packet arrival-rate.

摘要翻译： 一种从节点动态地调整列车中发送的分组数量以反映到达网络中节点的分组速率的机制。 在优选实施例中，节点具有分组控制器，该分组控制器确定在列车中发送的最佳分组数目。 该节点还具有定时器间隔，这是在发送下一列火车之前等待的最大时间。 分组控制器对分组到达率进行采样，并计算在列车中接收可配置常数数据包的经过时间。 该经过时间被称为采样间隔。 当采样间隔从历史采样间隔显着变化时，分组控制器仅校准最佳数据包数。 一个明显的变化是大于或小于历史间隔时间的预定百分比。 当定时器间隔到期时（称为超时），分组控制器将最佳分组数设置为超时之前累积的分组数，这使分组到达速率确定分组数 应该接受培训。 此外，在最佳分组数量上没有相应增加的情况下发生的超时导致分组控制器首先将最佳分组数量降低一小部分，然后在没有接收分组的情况下进行背对背超时， 分组控制器导致最佳分组数量下降到在超时之前累积的当前分组数量的更剧烈的下降。 这个超时处理消除了分组到达率的小变化。

摘要： An improved method and apparatus are provided for producing transmission control protocol (TCP) checksums using internet protocol (IP) fragmentation. A transmission control protocol module receives packet data to be transmitted and prepares a first internet protocol data fragment without a checksum for the received packet data. The first internet protocol data fragment is transmitted. Collecting checksum is performed during the transmission of the first internet protocol data fragment. Then an internet protocol header fragment including the collected checksum is transmitted.
