Abstract: A method and apparatus for management and control of remote computer resources. The method and apparatus creates and maintains a hierarchical data model for determining the characteristics and state of a particular remote computer resource to ensure the most appropriate control system is used to manage that particular remote computer resource. The data model used sorts and categorizes remote computing resources into groups and assigns resources from within these groups to users according to the user's needs and rights and the characteristics of the computing resources within each group. The state of the remote computing resource is tracked and automatically changes the state in accordance with changes in external variables or internal logic rules.

Abstract: A management layer method and apparatus for dynamically assigning computer users to remote computer resources according to predetermined rules and irrespective of remote viewer protocol utilized by the user. The method and apparatus is capable of managing hundreds of thousands of users across multiple physical sites and is operable with a wide variety of network, Internet, and application solutions. The method and apparatus is useful for an increasing mobile contemporary workforce in a world where the need for around the clock coverage coexists with the ever present possibility of catastrophic network failure.

Abstract: A system and method for migrating a computer to another computer having dissimilar hardware, wherein a preparation stage for the transfer of a disk image between the origin and target computer comprise analyzing the origin computer and modifying certain parameters therein while operating under its native operating system. After the modification an image of the origin computer is taken and sent to the second computer. The second computer can then boot the image as the necessary changes for booting the target machine were made at the origin computer. The invention is particularly useful for transferring physical computer to a virtual machine environment, where it minimizes the time the origin computer is out of service, where the transfer may occur remotely to the origin computer or the target computer. Most importantly, the invention provides a very high rate of success in migrating a physical system to a virtual system.

Abstract: The present invention can be used to facilitate the integration of wireless capability provided by wireless access points into an enterprise computer network. A gateway server is interposed between wireless access points and protected networks to provide security and integration functions, for example, authentication, access control, link privacy, link integrity, and bandwidth metering in various embodiments. Use of such a gateway server allows substantial control to be gained over network access even with the use of relatively simple access points. In general, such a gateway server receives a request to access the protected network. An authentication subsystem of the gateway server authenticates the user, preferably by accessing an external authentication server and returns a role to the authenticated user. An access controller in the gateway server provides differential access to the protected network based on the user's assigned role.

Abstract: A host computer, coupled to a peripheral device by its system bus, identifies an available input/output address and designates that input/output address as being assigned to that peripheral device. After identification of the available input/output address, the host computer transmits a logic trigger signal in the form of a sequence of write commands that write the assigned input/output address, as well as other configuration parameters, to an infrequently used input/output address. In response to the logic trigger, the peripheral reads and stores the assigned input/output address and other configuration parameters from the host computer's data bus, The configuration parameters and the assigned input/output address are then written to an EEPROM for non-volatile storage. After this configuration is established, the peripheral device automatically retrieves the stores configuration parameters and assigned input/output address from the EEPROM every time the host computer is turned on or is otherwise reset.

Abstract: The nodes of a repeater interface controller which repeats data packets received from one segment of a local area network onto the remaining segments of the local area network include loopback circuitry that allow the data packets received from the one segment to be repeated back onto the one segment in addition to the remaining segments of the local area network, thereby allowing the integrity of the one segment to be verified.

Abstract: A repeater interface controller receives a data packet at one of a plurality of port nodes from an associated segment of a local area network. The port nodes determine a priority port node, if more than one port node receives a data packet at substantially the same time, and transmit the data packet from the priority port node to a central node. The central node receives the data packet, repeats the data packet from the priority node, and transmits the repeated data packet to the non-priority port nodes. Each non-priority port node receives the repeated data packet and transmits the repeated data onto its associated segment. Each port node further includes a partitioning port state machine which monitors its associated segment and partitions the segment from the repeater interface controller when the partitioning port state machine detects a collision in a predetermined number of consecutive data packets.
