Abstract: In one embodiment, the present invention is a method and an apparatus for failure-resilient forwarding of data over a computer network. In one embodiment, a marker is introduced into the data stream, e.g., at the sending node, and allows, in turn, forwarding nodes and/or receivers to efficiently track data stream reception. The marker functions as a checkpoint for the data transport process, and is identified and indexed at each forwarding node and receiver. Each receiver saves the marker prior to delivering data to an application, thereby designating a point in the data stream at which all preceding data is confirmed to have been delivered to the application. Thus, if a forwarding node fails, the receiver may request stream data from an alternate forwarding node by specifying to the alternate forwarding node to provide data starting from the marker.

Abstract translation: 在一个实施例中，本发明是用于在计算机网络上进行数据故障恢复转发的方法和装置。 在一个实施例中，标记被引入数据流，例如在发送节点，并且允许转发节点和/或接收器来有效地跟踪数据流接收。 标记用作数据传输过程的检查点，并在每个转发节点和接收器处被识别和索引。 每个接收器在将数据传送到应用程序之前保存标记，从而指定数据流中的所有先前数据被确认已被递送到应用的点。 因此，如果转发节点发生故障，则接收方可以通过指定备用转发节点从标记开始提供数据来从备用转发节点请求流数据。

Abstract: A number of improvements in network adapters that offload protocol processing from the host processor are provided. Specifically, a mechanism for improving connection establishment in a system utilizing an offload network adapter is provided. The connection establishment mechanism provides the ability to offload connection establishment and maintenance of connection state information to the offload network adapter. As a result of this offloading of connection establishment and state information maintenance, the number of communications needed between the host system and the offload network adapter may be reduced. In addition, offloading of these functions to the offload network adapter permits bulk notification of established connections and state information to the host system rather than piecemeal notifications as is present in known computing systems.

Abstract: Method, apparatus and computer program product are configured to perform computer monitoring activities; to collect information regarding computer system status during the computer monitoring activities; to detect a problem in dependence on the information collected during the computer monitoring activities; and to determine whether to launch a diagnostic probe when the problem is detected. The monitoring activities may be performed on a periodic or event-driven basis. The determination whether to launch a diagnostic probe is based on a rule included in a hierarchy of rules. The hierarchy of rules is based on problem tickets; system logs; and computer system configuration information.
