Steering data communications packets for transparent, bump-in-the-wire processing among multiple data processing applications in a link-level data communications switch, the switch including data communications ports, a port connected to a first data communications network and another port connected to a second data communications network, other ports connected to the data processing applications, the switch also including rules governing the steering, including receiving in the switch from the first network data communications packets directed to the second network, each packet containing a source network address and a destination network address and steering by the switch each packet among the applications and through an egress port, such steering carried out only in accordance with the rules, using neither the source network address of the packet, the destination network address of the packet, nor any link-level identifier of any application.

A method and system for improving communications in data communications networks which provide network emulation. The method and system accomplish their objects via communications equipment adapted to do the following: implant a number of distributed-redundant gateways in an emulated network; and dynamically assign access to operational distributed-redundant gateways. In one embodiment, the network emulation is an Asynchronous Transfer Mode Emulation Local Area Network (ATM ELAN), and the distributed-redundant gateways operate as default Internet Protocol (IP) gateway utilized by LAN Emulation Clients (LE Clients) of the ATM ELAN. Also in one embodiment, the dynamic assignment of access is done such that the data communications loading associated with the default IP gateway is distributed throughout a data communications network.

A computer system includes a computer chassis housing a processor and having a dust filter disposed in an airflow pathway through the computer chassis. A plurality of electrodes is disposed across an area of the dust filter, and a voltage source is provided having a negative terminal and a positive terminal. A controller selectively couples a first subset of electrodes to the negative terminal and selectively couples a second subset of electrodes to the positive terminal, wherein a voltage differential between the first subset of electrodes and the second subset of electrodes is sufficient to cause electrostatic movement of dust from an area of the dust filter near the first subset of electrodes to an area of the dust filter near the second subset of electrodes.

An ELAN having redundant default gateways is attached to an asynchronous transfer mode (ATM) communications network. The ELAN's redundant default gateways are comprised of a first and second routers. The first router is associated with a primary default gateway and the second router is associated with a backup default gateway. Both the primary and backup default gateways are connected to the ELAN and both the primary and backup default gateways are configured with a default gateway IP address and associated MAC address. Initially, the primary default gateway registers the default gateway MAC address, thereby becoming the active default gateway. While the primary default gateway is active, the backup default gateway continually attempts to register the default gateway MAC address. When the primary default gateway fails, the backup default gateway will be able to successfully register the default gateway MAC address and take over the responsibilities of the primary default gateway and become the active default gateway.

A method of cleaning a dust filter includes applying a negative electrical potential to a first electrode in a first area of a dust filter and applying a positive electrical potential to a second electrode disposed in a second area of the dust filter, wherein a voltage differential between the first and second electrodes is sufficient to cause electrostatic movement of dust from the first area to the second area. Then, the method further includes applying a negative electrical potential to the second electrode and applying a positive electrical potential to a third electrode disposed in a third area of the dust filter, wherein a voltage differential between the second and third electrodes is sufficient to cause electrostatic movement of dust from the second area to the third area, and wherein the first, second and third areas are generally linearly arranged.

Apparatus and method for automatically testing hardware and software components of a system. A request type message is generated in the software component of the system. A request-type message, including a destination address and a source address, is made to traverse the transmit channel of the system. The destination address and source address are swapped, i. e. , interchanged, and the message is wrapped into the receive channel where it is forwarded to the software component for further analysis. Modification is in the transmit channel to modify the message by swapping the source address and the destination address to preclude discarding of the message by the receive channel.

A communication network having a plurality of routers, each connected to a host system by a LAN network and interconnected by a switched network, the common network using a shared or common IP and MAC address in the routers forming a subnet. Host systems on the same subnet use the shared or common IP address as their default gateway address when accessing host systems on another subnet.
