    摘要： The invention improves query response latency in a peer-to-peer network. The invention augments core neighbors included in a neighbor list of a peer node by selecting auxiliary neighbors for inclusion in the neighbor list of the peer node of a peer-to-peer network. In one embodiment, a method includes maintaining query frequency information associated with each of a plurality of peer nodes of the peer-to-peer network, selecting at least one of the peer nodes of the peer-to-peer network as an auxiliary neighbor using the query frequency information, and updating a neighbor list to include the at least one peer node selected as the at least one auxiliary neighbor. The core neighbors stored at a peer node attempt to minimize the worst-case query latency for that peer node. The auxiliary neighbors stored at the peer node attempt to reduce the average query latency for that peer node. The auxiliary neighbors may be used in any peer-to-peer system, such as Pastry, Tapestry, Chord, SkipGraph, and the like.

    摘要： A method of grouping nodes within a distributed network is provided. The example method includes performing a leader node self determination operation by which each node within the distributed network determines whether to become a leader node or a non-leader node, each leader node being the leader of a group including at least one node. Next, requests are sent, from each leader node, requesting at least one non-leader node to join the group associated with the leader node. First received requests are accepted, at each non-leader node, such that accepting non-leader nodes transition from a non-leader node to a dependent node dependent upon the requesting leader node. A next set of requests are sent, from each remaining non-leader node, requesting to join the group associated with at least one leader node. A determination is made, at each requested leader node, as to whether to accept the non-leader node into the group associated with the requested leader node. Based on the determination, at each requested leader node, the non-leader node is either accepted into the group associated with the requested leader node, or is alternatively rejected from the group.

    摘要： Disclosed is a mobile station having an expanded storage space, and a method of retrieving a file stored in a remote storage server. The method may include determining whether the file is locally stored or remotely stored, deleting files in a local storage to provide space if the file is determined to reside in a remote storage server, downloading the file from a remote storage server over the Internet by prefetching a portion of the file from the remote storage server, and opening the prefetched portion of the file while concurrently downloading a remaining portion of the file from the remote storage server.

    摘要： Techniques for logging data pertaining to the operation of a data stream processing server. In one set of embodiments, logging configuration information can be received specifying a functional area of a data stream processing server to be logged. Based on the logging configuration information, logging can be dynamically enabled for objects associated with the functional area that are instantiated by the data stream processing server, and logging can be dynamically disabled for objects associated with the functional area that are discarded (or no longer used) by the data stream processing server. In another set of embodiments, a tool can be provided for visualizing the data logged by the data stream processing server.
