  • Patent number: 7987257
    Abstract: Techniques are described for monitoring performance of a network. Particularly, network devices within the network exchange routing communications in accordance with one or more routing protocols, such as the Border Gateway Protocol (BGP), to automatically establish a community for monitoring performance throughout the network. Upon establishing the community, the network devices of the community exchange performance probes to collect comprehensive performance information for the network. This performance information may be aggregated via one or more computing devices. Using the aggregated performance information, numerous network performance characteristics may be computed, including delay, jitter, throughput, availability and packet loss.

  • Patent number: 5634033
    Abstract: A high performance scaleable hardware architecture for a disk array storage subsystem which supports RAID modes 0, 3, 4 and 5. The architecture features a high bandwidth parity calculation engine, a buffered PCI interface operating at the full speed of the PCI bus, and a dedicated local memory. The dedicated local memory is dual ported so that PCI and parity operations may operate concurrently. The architecture of the disk array controller allows parity calculations and memory block moves to occur without interfering with the controller processor or its associated memory, freeing the controller processor to manage array task control. The array controller configuration allows simultaneous operation of data block moves between storage I/O devices and local memory; data block moves between host SCSI connections and local memory; parity calculations; and normal CPU memory fetches, queued operations for block moves and queued operations for parity tasks.

  • Patent number: 5111085
    Abstract: A first inverter circuit is coupled between a first voltage source and a reference potential by a plurality of cascaded transistors. Each of the cascaded transistors has a control gate which may be selected to bring the resistance of the transistor into circuit with the inverter circuit to control the charging rate of a distributed capacitance. An output circuit coupled to the first inverter circuit provides the distributed capacitance and an inverted buffered output. The output circuit also includes an output which may be connected to another circuit of the present invention to form a cascaded delay circuit and to receive a reset signal for resetting the cascaded delay circuit.

  • Patent number: 4947395
    Abstract: For LSI/VLSI integrated circuits which inherently have an address decoder and a data bus, a scan testing method and apparatus is presented which does not require additional pin connections to be dedicated for scan test implementation. Counter to the Joint Test Action Group approach, the present invention uses additional registers, multiplexers, and decoders in conjunction with the existing buses to provide test access to otherwise embedded layers of logic circuitry, without the addition of a single pin connection to a integrated circuit chip package. Further, since this test method and apparatus uses the data bus and registers just as the rest of the chip, slow and complex d.c. level shifting equipment is not required.

  • Patent number: 4868430
    Abstract: A digitally controlled timing circuit for providing an output pulse signal precisely delayed with respect to an input signal irrespective of the time of occurrence of a system clock, but which uses the precision of the system clock to self-correct any inaccuracy in the delay includes a plurality of delay elements, the delay period of a respective one of which is adjustable, coupled between an input terminal, to which an input terminal is applied, and an output terminal, from which a delayed output signal is to be derived. Coupled to the input terminal and the plurality of delay elements is a toggled flip-flop which, with the delay elements, during a calibrate mode, forms an adjustable oscillator and generates a sequence of signals the lapse of time between successive ones of which is established by delays imparted by selected ones of the delay elements. The delays imparted by selected ones of the delay elements.
