  • Patent number: 7397764
    Abstract: Multiple fiber channel (FC) storage area networks (SANs) are interconnected over wide-area networks (WANs) to form a long-distance (e.g., greater than about 10 km) distributed storage area network (DSAN) that includes FC to Internet Protocol (IP) over WAN (e.g., SONET or gigabit Ethernet (GE)) gateways that interwork the FC buffer-to-buffer and IP/WAN flow-control mechanisms appropriate to either the SONET or GE link layers using an additive increase, multiplicative decrease (AIMD) congestion avoidance algorithm. The gateways effectively spoof the FC buffer-to-buffer credit mechanism on the FC-interface side of the gateway, while using an IP Internet control message protocol (ICMP) quench mechanism on all WAN links and additionally the IEEE 802.3 pause packet flow control mechanism on gigabit Ethernet (GE) WAN links in combination, in both cases, with a rate-throttling mechanism at the FC<->IP converter.

  • Patent number: 7356663
    Abstract: The present invention provides a method and apparatus for searching multiple strings within a packet data using deterministic finite automata. The apparatus includes means for updating memory tables stored in a layered memory architecture comprising a BRAM, an SRAM and a DRAM; a mechanism to strategically store the relevant data structure in the three memories based on the characteristics of data, size/capacity of the data structure, and frequency of access. The apparatus intelligently and efficiently places the associated data in different memories based on the observed fact that density of most rule-sets is around 10% for common data in typical network intrusion prevention systems. The methodology and layered memory architecture enable the apparatus implementing the present invention to achieve data processing line rates over 2 Gbps.

  • Patent number: 5886599
    Abstract: An improved circuit interrupter having a solenoid in series with the line and load terminals with an armature operable to activate a trip mechanism within the circuit breaker upon experiencing current levels indicative of short circuit conditions. The traditional solenoid coil is replaced with a free form conductor stamped in a serpentine pattern with adjacent legs deformed slightly in opposite directions to permit an electromagnetic material to be disposed therebetween. Current is directed through the conductor progressively back and forth through the serpentine pattern and creates a magnetic field in the electromagnetic material which is sufficient to activate an armature when current levels approximate short circuit conditions.

  • Patent number: 5522462
    Abstract: In a plate heat exchanger having a welded plate pair comprising first and second plates (2, 4) which are welded together at a contact region (19), a by-pass area (22) is defined between the plates on the inboard side of the contact region (19). The plates (2,4) are so shaped and arranged that a second by-pass area (22a) similar to the first, is defined between the second plate (4) and the first plate (2a) of an adjacent, similar, plate pair, on the inboard side of a gasket (28) clamped between the two plate pairs. A gasket groove (18) in the first plate has an inner side wall which is substantially continuous and which is of fixed or variable height substantially greater than zero.
