  • Patent number: 8549124
    Abstract: A method, apparatus, and computer program product for discovering network paths between network devices in a distance-vector network are provided. The method may include providing a node model of network devices in a distance-vector network. The node model may include a network address corresponding to a network device. The network address may be used to query the network device for routing information. This routing information may be used to identify another network address corresponding to a second network device, and to identify a path from the first network device to the second network device. These devices and the path therebetween may be mapped in the node model. Finally, the second network device may be queried for subsequent routing information to identify and map subsequent devices and paths.

  • Patent number: 8195977
    Abstract: A computer implemented method, apparatus, and computer usable program code for network fault isolation. A plurality of real-time path traces is performed between the sender and the receiver to form a plurality of trace paths in response to receiving a request for the network fault isolation between a sender and a receiver. A determination is made as to whether an asymmetry is present between the sender and the receiver from the plurality of trace paths. A set of routers is identified with each trace path in the plurality of trace paths to form a plurality of identified routers. Each event stored is identified for the plurality of identified routers to form a set of identified events.

  • Patent number: 7779123
    Abstract: A system and associated method for building a network model of a network for a network management application. The network management application discovering a router discovers peering routers using network reachability information in a routing protocol. Undiscoverable peering routers are created within the network model by the network management application from network reachability information. Also a local subnet for the router, a remote subnet for a peer, a remote interface between the router and the peer also may be created to model the network in a network management application from information from the routing protocol.

  • Publication number: 20090304468
    Abstract: A drill bit has a cutting face for engaging a workpiece. The cutting face forms an annular cut. A mouth is bounded by the cutting face and receives material of the workpiece from within the annular cut, as cutting progresses. An internal passage has a mouth through which this material can leave the bit.

  • Publication number: 20090210523
    Abstract: A network management method and system. The method includes identifying and accessing a network device. A set of software loopback interfaces configured for the network device is retrieved. A first set of Internet protocol (IP) addresses associated the set of software loopback interfaces is retrieved. A second set of IP addresses associated with the first set of IP addresses is retrieved. A set of next-hop interfaces is retrieved. A network management topology model based on the network device, the set of software loopback interfaces, the first set of IP addresses, the second set of IP addresses, and the set of next-hop interfaces is generated. The network management topology model indicates that each IP address of the second set of IP addresses that is adjacent to an IP address of the first set of IP addresses is reachable via an associated next-hop interface of the set of next-hop interfaces.

  • Publication number: 20090133890
    Abstract: An attachment is for a power tool having a chuck. The attachment has a connection portion in the form of a shaft for connecting the attachment with the tool, during use, by attachment in the chuck. The attachment further has a blade portion which, in use, is offered to a surface indicated at, and to which hammer blows are transmitted from the hammer tool, thereby causing the blade portion to cut into the surface.

  • Publication number: 20090074390
    Abstract: Apparatus for simulating a solid fuel flame includes a frame within which is mounted a screen. An enclosure is mounted below the screen having a frosted glass refractor panel forming a top wall of the enclosure. A cylindrical container is rotatably mounted within the enclosure. A motor rotates the container on a support. The container is partially filled with a red or brown coloured liquid. Lamps or LED's within the enclosure are operable to shine light through the coloured liquid in the container and through the refractor panel onto the screen. Movement of the coloured liquid, which may be enhanced by internal projections in the container, causes flickering of the light projected onto the screen to give a flame effect simulating a solid fuel fire.

  • Publication number: 20090056150
    Abstract: A blade 1 comprises a strip 2 having a main body portion 4 and an edge portion 6. Cutting medium 8 in the form of a grit is secured to the strip 2 by braze material. The grit may be diamond, tungsten carbide, cubic boron nitride, a ceramic material, a ceramic-based material or a cermet material. The edge portion 16 is thinner than the main body portion 14.

  • Patent number: 7137316
    Abstract: A saw blade is formed from a blank which has an edge. Inserts, such as tungsten carbide are inserted in apertures in the blank and a finishing cut is then made along the line to produce a series of teeth, each having a point within the body of the insert, and thus formed by the relatively hard material of the insert. Fingers of the inserts provide a root which holds the insert in position during use.
