摘要： Flash memory systems and methods for efficiently locating meta-data structures on solid-state devices, such as, flash-based memory devices, which allows for fast reconstruction of metadata structures are provided. These systems and methods place checkpoints, which identify the location of metadata structures, intelligently on the device so as to permit a more efficient method of locating such checkpoints. These techniques ensure best wear-leveling as all blocks on the device undergo the same wear-leveling strategy. These systems and methods further provide a free block maintenance strategy that provides blocks freed by garbage collection for future checkpoint writes.

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： Methods and apparatus are provided for controlling flow rates of a plurality of data packet flows into a queue 4 corresponding to a resource 3 of a network device 1. The flows comprise a set 7 of non-responsive flows, and a set 8 of other flows which may comprise responsive flows and/or flows whose responsiveness is unknown. The flow rates are managed in accordance with a queue management scheme such that adjustments are made to each flow rate in dependence on excess bandwidth in the resource, the amounts of the adjustments being dependent on one or more adjustment parameters for each flow. An error signal is generated based on the deviation from a desired allocation ratio of the ratio of the total flow rates into the queue 4 for the sets of flows 7, 8. At least one adjustment parameter for at least one flow is then varied in dependence on the error signal in such a manner as to reduce the aforementioned deviation. A closed-loop control scheme thus operates in conjunction with the underlying queue management scheme to promote fair bandwidth allocation even in the presence of a mix of responsive and non-responsive flows.

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.
