  • Method and system for hardware simulation
    Patent number: 7047176
    Abstract: A system and method for simulating a networked system for testing of embedded software on an emulated hardware device. The system provides for automated generation of a simulated hardware and facilitates testing of embedded software response to simulated error conditions created by the simulated hardware. Communications from the embedded software are intercepted at a low software level and redirected from the emulated hardware device to the simulated hardware.
    Type: Grant

  • Multiprotocol label switching routers
    Patent number: 6885677
    Abstract: In one aspect, a method of using a general purpose computer 8 as an MPLS-enabled label switched router includes executing software on the general purpose computer 8 that allows it to communicate with other label switched routers using label distribution protocol. The general purpose computer 8 includes a central processor 10, a memory 12, network interface cards 30 and 32 and also typically includes local I/O such as a keyboard 22, a mouse 24 and a display device 20 for communicating with a local user.
