  • Publication number: 20140115706
    Abstract: A shadow network, which can be a virtual reproduction of a real, physical, base computer network, is described. Shadow networks duplicate the topology, services, host, and network traffic of the base network using shadow hosts, which are low interaction, minimal-resource-using host emulators. The shadow networks are connected to the base network through virtual switches, etc. in order to form a large obfuscated network. When a hacker probes into a host emulator, a more resource-intensive virtual machine can be swapped in to take its place. When a connection is attempted from a host emulator to a physical computer, the a host emulator can step in to take the place of the physical computer, and software defined networking (SDN) can prevent collisions between the duplicated IP addresses. Replicating the shadow networks within the network introduces problems for hackers and allows a system administrator easier ways to identify intrusions.

  • Patent number: 7232780
    Abstract: The invention presents yttria elements containing high-density chrome based refractory composites, which consist of: (A) Fused polymeric compound as aggregate, containing: 40 to 50 wt % of particles in size from 1 to 4 mm and 15 to 25 wt % of particles in size below 1 mm; (B) A matrix consisting of fused polymeric compounds with particle sizes below 66 ?m, active sintered Al2O3, active industrial Cr2O3 and Y2O3, (C) Binders accounting for 2.5 to 3.5 wt %. Since Y2O3 has resistance to the slag corrosion and penetration with its compatibility with slag, it has been introduced to activate the major component Cr2O3 crystal lattice in favor with Al2O3 so that it helps to reduce the sintering temperature, increase the rate of finished products as well as reduce the manufacturing cost.

  • Publication number: 20060069760
    Abstract: Methods and apparatus to reconfigure parameters for establishing a link with a new host after a computer is moved to a new location or a new network. A computer-implemented method for networking includes steps of examining an established link for a need to establish a new link, establishing the new link by selecting a network profile from a plurality of network profiles stored in a profile database, and reconfiguring parameters for a current network setting automatically without user input. The network profile contains a plurality of configuration parameters for establishing links.
