    摘要: For port scanning an authentication bit sequence is created as an output of an authentication transformation, the authentication transformation having as input at least a given destination address and a given secret key. The authentication bit sequence is embedded in at least one authentication port scan event packet comprising the given destination address. At least one authentication port scan event packet is broadcast. Then, further port scan event packets are broadcast with given port identifiers and the given destination address. For port scanning detection, a received authentication bit sequence is derived from a least one authentication port scan event packet with identical source and destination addresses. Further port scan event packets are accepted with given port identifiers and the given destination address if authentication is given.

    摘要: A network device and a computer program element are introduced for controlling data packet flows in a network device by manipulating data packets according to an actual manipulation rate. Amongst data packets received by a network device such as a router, data packets are identified that are marked with a pattern according to a congestion notification scheme. A pattern rate of data packets comprising such a pattern is determined, and the actual manipulation rate is determined subject to the pattern rate.

    摘要: Methods for searching a range in a set of values in a network with distributed storage nodes. An example of a method for searching a range in a set of values in a network with distributed storage nodes according to the invention comprises the following steps. First, the range is divided up into a set of subranges by means of a hierarchical structure. Then, a query packet is generated for said set of subranges and transmitted to the distributed storage nodes for performing the query.

    摘要: Provided are a system, method, and computer program product for managing cache memory to cache data units in at least one storage device. A cache controller is coupled to at least two flash bricks, each comprising a flash memory. Metadata indicates a mapping of the data units to the flash bricks caching the data units, wherein the metadata is used to determine the flash bricks on which the cache controller caches received data units. The metadata is updated to indicate the flash brick having the flash memory on which data units are cached.
