摘要： Embodiments of the present invention provide systems, articles of manufacture and methods for a telematic parametric speed metering system. In one embodiment, a system may determine a vehicle's location and speed. Once the location has been determined, corresponding geographical zone based speed limits and/or other information may be acquired via internal memory or data transmission. The speed of the vehicle may then be compared against the speed limits for the zone. If the vehicle's speed exceeds those speed limits, one or more of a plurality of actions may be performed including (but not limited to) warning the driver via a visual or audio signal, informing an authority agency via data transmission, logging the excessive speeding condition (e.g., time, date, speed, location, driver name, etc).

摘要： A Resource Reservation System includes a Token Generation Unit (TGU) which generates and circulates among nodes of a communications system a Slotted Token (SLT) message having sub-fields to carry identification number for each input port in a node and the resource available for each input port. On receiving the message the Resource Control Unit (RCU) in each node can write port identification number, available resource in appropriate sub-fields of the SLT message, and reserve resources in other nodes by adjusting information in the sub-field associated with the other nodes.

摘要： An intrusion detection system (IDS) comprises a network processor (NP) coupled to a memory unit for storing programs and data. The NP is also coupled to one or more parallel pattern detection engines (PPDE) which provide high speed parallel detection of patterns in an input data stream. Each PPDE comprises many processing units (PUs) each designed to store intrusion signatures as a sequence of data with selected operation codes. The PUs have configuration registers for selecting modes of pattern recognition. Each PU compares a byte at each clock cycle. If a sequence of bytes from the input pattern match a stored pattern, the identification of the PU detecting the pattern is outputted with any applicable comparison data. By storing intrusion signatures in many parallel PUs, the IDS can process network data at the NP processing speed. PUs may be cascaded to increase intrusion coverage or to detect long intrusion signatures.

摘要： A flow control method and system including an algorithm for deciding to transmit an arriving packet into a processing queue or to discard it, or, in the case of instructions or packets that must not be discarded, a similar method and system for deciding at a service event to transmit an instruction or packet into a processing queue or to skip the service event. The transmit probability is increased or decreased in consideration of minimum and maximum limits for each flow, aggregate limits for sets of flows, relative priority among flows, queue occupancy, and rate of change of queue occupancy. The effects include protection of flows below their minimum rates, correction of flows above their maximum rates, and, for flows between minimum and maximum rates, reduction of constituent flows of an aggregate that is above its aggregate maximum. Practice of the invention results in low queue occupancy during steady congestion.
