Methods and systems for full pattern matching in hardware

Номер: US0008458796B2

Methods and systems are provided for hardware-based pattern matching. In an embodiment, an intrusion-prevention system (IPS) identifies a full match between a subject data word comprising subject-data blocks and a signature data pattern comprising signature-data blocks. The IPS receives the subject data word via a network interface, and thereafter makes a partial-match determination that two or more but less than all of the subject-data blocks respectively match the same number of the signature-data blocks stored in partial-match hardware with respect to both value and position. Thereafter, the IPS makes a full-match determination that all of the subject-data blocks respectively match all of the signature-data blocks stored in the IPS's full-match hardware with respect to both value and position. The IPS then stores an indicator that the full-match determination has been made, and may carry out one or more additional intrusion-prevention responses as well.

Receive and transmit blocks for asynchronous transfer mode (ATM) cell delineation

Номер: US0006269096B1

Receive and transmit blocks for asynchronous transfer mode (ATM) cell delineation are disclosed. The receive block has a plurality of cell delineation blocks, a memory controller, a memory and a bus controller. The transmit block has a bus controller, a plurality of queue selection devices, a plurality of memory queues and a plurality of cell delineation blocks. According to one implementation, the bus controllers receive address mode/select signals and operate to respond to one of a plurality of subsets of port addresses on the ATM physical layer responsive to the address mode/select signals.

Interleaved read/write operation in a data switch

Номер: US0006853643B1

An interleaved read/write operation in a data switch determines a read memory of at least two memories that has been accessed during a most recent read operation. A memory controller determines a write memory different from the read memory and accesses a cell buffer list associated with the write memory to determine a buffer to store the cell. The switch writes the cell to the buffer to interleave read/write operations between the read memory and the write memory.
