摘要： A system adapted to process network traffic includes at least one processing engine configured to receive network data being transferred over a network and generate metadata relating to the data. The system includes at least one rule engine configured to receive and process the metadata to generate an output, and at least one selection engine configured to receive and process the rule engine output to determine whether the network data is to be processed by a further component and/or whether the network data is to continue to be transferred over the network. The processing engine, rule engine and selection engine can be implemented in system hardware or firmware, and the further component can be software for execution on another processor.

摘要： There is provided a hardware device for monitoring and intercepting data packetized data traffic at full line rate. In preferred high bandwidth embodiments, full line rate corresponds to rates that exceed 100 Mbytes/s and in some cases 1000 Mbytes/s. Monitoring and intercepting software, alone, is not able to operate on such volumes of data in real-time. A preferred embodiment comprises: a data delay buffer (208) with multiple delay outputs (216); a search engine logic (210) for implementing a set of basic search tools that operate in real-time on the data traffic; a programmable gate array (206); an interface (212) for passing data quickly to software sub-systems; and control means for implementing software control of the operation of the search tools. The programmable gate array (206) inserts the data packets into the delay buffer (208), extracts them for searching at the delay outputs and formats and schedules the operation of the search engine logic (210). One preferred embodiment uses an IP co-processor as the search engine logic.

摘要： This invention relates to a pumping system. The design of the system is such that bi-directional operation can be achieved using a significantly smaller and hence lighter unit than those currently available. It uses the direction of rotation of the drive shaft to control the opening and closure of the by-pass means for controllably returning the fluid to the first reservoir.
