  • Patent number: 11184258
    Abstract: A monitoring system is disclosed that achieves the benefits of active monitoring by providing a holistic view of the network, while obtaining the granularity of a passive monitoring system by testing a large majority or all of the prefixes. In one embodiment, streaming updates of a forwarding plane are captured for devices in a network. Additionally, an initial state of the forwarding plane can be captured for each device. A time-series graph of the forwarding plane can be constructed. In the graph, each node can represent a device and each edge can represent a possible path for a prefix at a given point in time. Graph analysis techniques can be used to analyze the graph and detect errors. For example, cycle detection algorithms can be used on the forwarding plane data to detect microloops. Other techniques can be used to find black holes or capacity bottlenecks.

  • Patent number: 10336009
    Abstract: The color of object data that indicates the shape and the color of an object is reproduced faithfully when modeling an object. A model is formed by discharging droplets having the same color from droplet discharging units onto a medium, based on the same reference signal. Colorimetry is performed on the model, and a first-portion and a second-portion having a color with a higher density are specified. The liquid amount of droplets per unit area to be discharged from droplets discharging units that formed the first-portion and the liquid amount of droplets per unit area to be discharged from droplets discharging units that formed the second-portion are adjusted such that a difference in density of colors to be reproduced decreases. The object is modeled by repeating processing for discharging droplets from the droplet discharging units based on the object data.
