Abstract: 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.

Abstract: In general, techniques are described for performing work conserving packet scheduling in network devices. For example, a network device comprising queues that store packets and a control unit may implement these techniques. The control unit stores data defining hierarchically-ordered nodes, which include leaf nodes from which one or more of the queues depend. The control unit executes first and second dequeue operations concurrently to traverse the hierarchically-ordered nodes and schedule processing of packets stored to the queues. During execution, the first dequeue operation masks at least one of the selected ones of the leaf nodes from which one of the queues depends based on scheduling data stored by the control unit. The scheduling data indicates valid child node counts in some instances. The masking occurs to exclude the node from consideration by the second dequeue operation concurrently executing with the first dequeue operation, which may preserve work in certain instances.
