  • Publication number: 20040093430
    Abstract: A method and system are disclosed for managing communication in a computer network using aliases of computer network addresses. In accordance with exemplary embodiments of the present invention, a primary network address and at least a secondary network address are assigned to each server among a plurality of servers connected to a switch. The secondary network address of the server is an alias for the primary network address of the server. An information packet is transmitted from a first server of the plurality of servers to the switch. A source address included in the information packet is the primary network address of the first server. The switch modifies the source address included in the information packet received at the switch to be the secondary network address of the first server. The switch forwards the modified information packet to a second server of the plurality of servers.

  • Publication number: 20040008676
    Abstract: A first network device is configured to receive an information packet including a destination address from a source node. The first network device includes a first translation table for use in translating the destination address into an address indicator which is used in the computer network system to replace the destination address in the information packet and to denote a destination node specified by the destination address. A second network device is configured to receive the information packet including the address indicator. The second network device including a second translation table for use in translating the address indicator into the destination address. The second network device being configured to send the information packet including the destination address to the destination node denoted by the address indicator.

  • Publication number: 20040010619
    Abstract: A computer network system for interconnecting nodes using dynamic updates includes a first network device configured to receive an information packet including a destination address for a source node. The first network device includes a first translation table for use in translating the destination address into an address indicator which is used in the computer network system to replace the destination address in the information packet and to denote the destination node specified by the destination address. The computer network system includes a second network device configured to receive the information packet. The second network device includes a second translation table for use in translating the address indicator into the destination address. The second network device is configured to send the information packet including the destination address to the destination node denoted by the address indicator.

  • Publication number: 20040010618
    Abstract: A computer system for interconnecting nodes in a virtual network includes a first network device configured to receive an information packet including a destination address and a virtual network identifier from a source node. The first network device includes a first translation table for use in translating the destination address and the virtual network identifier into an address indicator which is used in the computer network system to replace the destination address in the information packet and to denote a destination node specified by the destination address. The computer network system includes a second network device configured to receive the information packet including the address indicator. The second network device includes a second translation table for use in translating the address indicator into the destination address and the virtual network identifier.

  • Patent number: 6000232
    Abstract: A refrigeration system is disclosed in which temperature regulation and energy efficiency are improved. Each compartment to be cooled is provided with a variable speed fan, the speed of which is controlled dependent on that compartment's temperature, the temperature required of that compartment, and the difference between required and actual temperatures for any other compartments. The temperatures are monitored continually and fan speeds altered so that the compartment furthest from its required temperature receives the most cooling (highest fan speed). An alternative embodiment is also disclosed wherein the speed of one compartment's fan is fixed and the other varied.
