摘要： A system enables a cell of data to be transmitted one time over a high speed data bus to an Ethernet switch system where it is then distributed to each of the destinations for which it is intended. A first group of buffers is for temporarily storing data that is to be delivered to only one destination. A second group of buffers is for holding the cells that are to be transmitted to a plurality of devices. In the described embodiment of the invention, the unicast and multicast cells are transmitted over the same line or bus. The invention further includes a switch processor that is formed to detect congestion within the switch fabric and to transmit a congestion rating to each device coupled to transmit and receive data through the switch fabric.

摘要： A thermal management system for an enclosure housing devices which generate heat inside the enclosure. A fan, whose speed is responsive to an input signal, has a gas flow output in communication with the enclosure. A filter is disposed in the gas flow path of the fan's output. At least one temperature sensor is disposed in the enclosure for measuring the temperature inside the enclosure. A controller adjusts the speed of the fan until the temperature inside the enclosure is within a predetermined range to ensure that the devices inside the enclosure do not overheat. A processor compares the signal input to the fan with the speed of the fan to determine the condition of the fan and, in response to the temperature sensor, determines the condition of the filter.

摘要： Methods and devices for qualifying a client machine to access a network, based on policies governing required protective measures, such as virus checking and operating system updates, are disclosed. A client machine must pass various checks to qualify for access. A client machine may be redirected to remediation resources that support efforts to bring the client machine into compliance with applicable network access requirements. A policy repository is updated regularly by vendors of protective measures. An administrator establishes user roles that are mapped to policy rule sets retrieved from the policy repository. The policy rule sets govern qualification of client machines for access to the network in accordance with the roles of the users of the machines. An access server is an intermediary between a client machine and the access manager. A client agent runs on the client machine and carries out checks, and reports the results via the access server to the access manager.

摘要： The present invention relates to methods and devices that support mobility of a client across a campus, particularly mobility across VLANs and subnets, while preserving the client's assigned IP address. Both layer 2 and layer 3 packets are supported. Mobility support most clearly applies to wireless clients, but could apply to other kinds of mobile connections, even to wired connections. A smart server is adapted to support multiple VLANs and to modify and redirect packets in sessions with a client that moves from one VLAN to another, preserving the client's assigned IP address. Two or more smart servers, in cooperation with a smart manger, modify packets and tunnel them between smart servers when a client that moves from one VLAN to another and from one smart server to another, again preserving the client's assigned IP address. A similar approach applies to support mobility of a client that moves between subnets that are supervised by two smart servers, with the second smart server acting on behalf of the first smart server and tunneling packets back and forth to the first smart server. Particular aspects of the present invention are described in the claims, specification and drawings.

摘要： The present apparatus and method of use comprises a system that enables a cell of data to be transmitted one time over a high speed data bus to an switch system where it is then distributed to each of the destinations for which it is intended. A fabric access device and a multiplex devices are each formed to have groups of buffers for buffering signals according to type. The first group of buffers is for temporarily storing data that is to be delivered to only one destination. The second group of buffers is for holding the cells that are to be transmitted to a plurality of devices. In those embodiments in which the unicast and multicast cells are transmitted over the same line or bus a parsing unit examines a field within the header portion of each cell to determine whether the cell is a unicast or multicast cell. If the cell is a unicast cell, it is temporarily stored within the unicast receive buffer set. If the cell is a multicast cell, then it is temporarily stored in the multicast buffer set. A memory whose contents include a table that is used for addressing purposes for the multicast cells.
