    摘要: The present invention addresses scalability and end-to-end reliability in overlay multicast networks. A simple end-system multicast architecture that is both scalable in throughput and reliable in an end-to-end way is used. In this architecture, the transfers between nodes use TCP with backpressure mechanisms to provide data packet transfers between intermediate nodes having finite-size forwarding buffers. There is also a finite-size backup buffer in each node to store copies of packets which are copied out from the receiver window to the forwarding buffers. These backup buffers are used when TCP connections are re-established to supply copies of data packets for the children nodes after their parent node fails, maintaining a complete sequence of data packets to all nodes within the multicast overlay network. The architecture provides end-to-end reliability, tolerates multiple simultaneous node failures and provides positive throughput for any group size and any buffer size.

    摘要: A risk assessment system and method includes an information system configured to disclose information to a third party. A risk determination model is configured to compute identifiability risk for on one or more records in storage. The identifiability risk is compared to a threshold prior to being disclosed wherein the information system is informed of the identifiability risk exceeding the threshold prior to disclosure to the third party.

    摘要: A method for constructing an overlay multicast tree to deliver data from a source to an identified group of nodes is provided in which a plurality of nodes are identified and mapped into multidimensional Euclidean space. A geometric region is constructing having a size that is the minimum size necessary to contain the source and all the nodes. Once constructed, a tree is created beginning at the source and including all of the nodes within the geometric region.

    摘要: A computer implemented method, apparatus, and computer usable program code for performing automatic planning in a compositional system. Parameter substitution is performed in response to receiving a planning language input. Actions are preprocessed in response to performing parameter substitution. A backward search is performed for potential solutions in response to preprocessing actions. A domain description is used for performing parameter substitution, preprocessing, and performing a backward search. Actions within the domain description have one or more inputs and one or more outputs. The planning language input specifies at least one goal and at least one action. A description of an action includes at least one description of action preconditions and at least one description of action effects. The action preconditions include predicates that must hold on input streams connected to the action in a valid workflow.
