Abstract: A combined switch and service processor module for a modular computer system is provided. The combined switch and service processor module comprises a switch portion; a service processor portion; and a data interface for communicating management information to other parts of the modular computer system. Wherein the service processor portion is operable to operate in master/slave relationship with a service processor portion of a further combined switch and service processor module of the modular computer system; and wherein the service processor portion is further operable automatically to synchronise management information with the service processor portion of the further combined switch and service processor via the data interface in accordance with the master/slave relationship.

Abstract: A method of assigning names to components of a networked computer system is provided. The networked computer system includes at least one modular computer system having at least one service processor module and a plurality of information processing modules removably received in a modular computer system housing. The method comprises: receiving at the service processor module a naming command message including a naming format from a management entity of the networked computer system. The method also comprises assigning at the service processor module a name to the service processor module and to the information processing modules received in the housing in accordance with the naming format; and transmitting a message from the service processor module to a domain name server of the networked computer system, the message including an IP address of each module and the name assigned to each respective module.

Abstract: A method and apparatus are provided for passing configuration information over a network. In one embodiment, the configuration information is passed between a DHCP server and a DHCP client and includes parameters not formally defined within DHCP. The parameters are therefore encoded into a vendor-specific portion of a DHCP message using at least one triplet comprising a code field, a length field, and a value field. The value field comprises a set of one or more name-value pairs. The code field includes an indication of encryption of the value field. In another embodiment, a fixed-function appliance device is attached to a network, and is booted using boot code and a configuration stored locally to the device. The device then downloads a network configuration, which is compared to the locally stored configuration. If the network configuration is different from the locally stored configuration, the network configuration is stored locally to the device.

Abstract: A system and method is provided for designing (or re-architecting) a personal digital assistant (PDA) as a portable thin client of a network. The portable thin client is a small, stateless, “plug and work” computer whose main function is to process all input and output for the user, as well as to manage communication with at least one server. All other computational tasks (or services) for the user of the PDA are performed on the server which is shared amongst a community of thin clients. As a result of re-architecting the PDA as a portable thin client, there is no need to download application(s) and operating system(s) running the application(s) to the PDA because the server—through the network—provides these services. In addition, no data is lost when a PDA is faulty or has to be changed.
