摘要： Preventing replay attacks on servers. At least one Bloom filter may be set up in a server for tracking requests received from clients. Identifying data may be generated for each request. The identifying data may be checked against the Bloom filter array. If a match is found, the message may be a replay and may be rejected. If a match is not found, the request identifying data may be added to the Bloom filter and the request may be processed.

摘要： A bridged network and a method for performing bridged network topology acquisition. The bridged network includes network segments and smart bridges having one or more ports. The network segments are interconnected by the smart bridges via the ports. Each of the smart bridges being configured to perform steps to accomplish the network topology acquisition. The method also performs steps to accomplish the network topology acquisition. The steps include an inventory construction that compiles a list of the ports that are connected to each of the network segments. Among the ports that are connected to any of the network segments the inventory construction respecting each port operates cooperatively so as to cause the list respecting each of the ports to converge rapidly to the state in which all the lists are similar and yielding a uniform segment inventory. The bridged network topology acquisition in each of the smart bridges operates cooperatively with the bridged network topology acquisition in other smart bridges in order to create a total network report from most recent segment inventories. The bridged network topology acquisition includes propagation, collection, and distribution. The bridges network topology acquisition affords better management of network topology changes.

摘要： A non-transitory computer-readable storage device includes instructions that, when executed, cause one or more processors to receive a sequence of hashes. Next, the one or more processors are further caused to determine locations of previously stored copies of a subset of the data chunks corresponding to the hashes. The one or more processors are further caused to group hashes and corresponding data chunks into segments based in part on the determined information. The one or more processors are caused to choose, for each segment, a store to deduplicate that segment against. Finally, the one or more processors are further caused to combine two or more segments chosen to be deduplicated against the same store and deduplicate them as a whole using a second index.

摘要： Systems, methods, and other embodiments associated with forensic snapshots are described. One example method includes creating a snapshot of an operational data. The example method may also include creating a hash tree by hashing lowest level data blocks of the snapshot to produce lowest level hashes. Creating a hash tree may also include repeatedly growing the hash tree bottom up by selectively hashing lower level hashes into higher level hashes until a root node is produced. The example method may also include providing a forensic data associated with the hash tree, where the forensic data is used to verify the integrity of the snapshot.

摘要： A sequence of hashes is received. Each hash corresponds to a data chunk of data to be deduplicated. Locations of previously stored copies of the data chunks are determined, the locations determined based on the hashes. A breakpoint in the sequence of data chunks is determined based on the locations, the breakpoint forming a boundary of a segment of data chunks.

摘要： A method for data deduplication includes receiving a set of hashes derived from a data chunk of a set of input data chunks 310. The method includes sampling the set of hashes 320, using an index indentifying data chunk containers that hold data chunks having a hash in the set of sampled hashes 330, and loading indexes for at least one of the identified data chunk containers 340. The method includes determining which of the hashes correspond to data chunks stored in data chunk containers corresponding to the loaded indexes 350 and deciding which of the set of input data chunks should be stored based at least in part on the determination.

摘要： A first distribution of cases over a first group of categories is received. A categorizer trained using a search-and-confirm technique classifies the cases into a second group of categories. A second distribution of the cases over the second group of categories is generated using results of the classifying. The first and second distributions are compared to identify differences between the first and second distributions.

摘要： A method includes receiving information about a plurality of data chunks and determining if one or more of a plurality of back-end nodes already stores more than a threshold amount of the plurality of data chunks where one of the plurality of back-end nodes is designated as a sticky node. The method further includes, responsive to determining that none of the plurality of back-end nodes already stores more than a threshold amount of the plurality of data chunks, deduplicating the plurality of data chunks against the back-end node designated as the sticky node. Finally, the method includes, responsive to an amount of data being processed, designating a different back-end node as the sticky node.
