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： 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： Mobile network services are performed in a mobile data network in a way that is transparent to most of the existing equipment in the mobile data network. The mobile data network includes a radio access network and a core network. A first service mechanism in the radio access network breaks out data coming from a basestation, and performs one or more mobile network services at the edge of the mobile data network based on the broken out data. These services may include caching of data, data or video compression techniques, push-based services, charging, application serving, analytics, security, data filtering, and new revenue-producing services, as well as others. This architecture allows performing new mobile network services at the edge of a mobile data network within the infrastructure of an existing mobile data network.
