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: 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.

Abstract: A solution for managing a computer infrastructure is provided. In particular, the solution can generate a set of tentative recovery segments for the computer infrastructure based on a related resource graph and a set of partition rules. The related resource graph can be generated based on a managed resource graph, which includes resource type information for each node in the managed resource graph. The set of tentative recovery segments can be used to manage the computer infrastructure and/or a set of recovery segments, which includes recovery characteristic(s) for each segment can be generated based on the set of tentative recovery segments and a set of recovery segment templates. In any event, the invention provides a solution that fully and/or partially automates the identification of recovery segments within a computer infrastructure, thereby enabling a more effective management of the computer infrastructure.

Abstract: A system and method for scalable status change detection in a network of nodes includes embedding node coordinate positions into a virtual map environment. A cluster of nodes are represented with a representative node to form a hierarchy of nodes and clusters where changes in a status of the representative node imply a status change in the nodes of the cluster. By selectively monitoring the representative nodes for the changes in status, the representative nodes create a capability for scalable monitoring of the network.

Abstract: One embodiment of the present method and apparatus for re-establishing anonymous data transfers between a first endpoint and a second endpoint in a network includes receiving, from a first node, the identity of a second node connected to the first node, where at least the first node is a neighbor node. A third node (a neighbor node) is then selected, and instructed to connect to the second node in order to establish a link for the path. In this manner, the first endpoint and the second endpoint remain unknown at least to each other (e.g., where “unknown” means that neither endpoint knows any identifying information, such as network address, about the other endpoint), and likely to all other nodes in the path as well. In another embodiment, a failure is detected at a neighbor node, where the neighbor node is part of an original path between the first endpoint and the second endpoint. The neighbor node's repair server is contacted for a repair node associated with the neighbor node, and a connection to the repair node is made such that the path is established in a manner that maintains anonymity of the first endpoint and the second endpoint relative to each other.

Abstract: One embodiment of the present method and apparatus for anonymous data transfers comprises connecting first and second network endpoints to at least one relay node and transferring data from the first endpoint to the second endpoint through the at least one relay node such that the first and second endpoints are not aware of each other's identities, e.g., are not aware of an ultimate source or destination of transferred data. In further embodiments, an information field specifying a number of times that a data transfer message (e.g., a request, response or get message) should be forwarded is altered so that no receiving node can inferentially identify an originating node.
