摘要： DLL devices are built with multiple MAC address instead of a single MAC address, and provide a multiple virtual DLL interfaces to the upper layers (3-7) in a computer. This results in a new class of multi-function computers for attachment to a network system which take advantage of the multiple virtual DLL interfaces, to increase performance of the respective functions executed by the computer. Thus, a new network interface control apparatus and a new class of multi-function computer systems for attachments to networks are provided. The memory in the medium access control device stores a plurality of additional network addresses in addition to the assigned network addresses. The address filtering logic includes circuits responsive to the additional network addresses, such as logic for blocking a particular frame on at least one of the plurality of data channels when the source and destination address of a particular frame are found in the additional addresses stored in the memory. The plurality of data channels served by the media access control device may reside on a single physical interface, or in independent physical interfaces as suits the needs of a particular design. A high performance design would include independent buffering and queuing structures for each of the data channels. An alternative design may include shared buffering and queuing structures for a plurality of functional modules in the connected computer which have independent side network addresses.

摘要： The present invention provides a method and an apparatus for facilitating high bandwidth transmissions of data through a computer network. The invention uses communications through a routed network, such as the Internet, to establish a communication pathway through a connection-oriented network, such as an ATM or a frame relay network. This technique effectively exploits the universal addressing structure of routed networks, such as the Internet, to establish high bandwidth connections through connect-oriented networks. The present invention also facilitates selection of a connection-oriented network for data transmissions from a plurality of connection-oriented networks based upon parameters such as availability and costs. One embodiment of the present invention facilitates connections through mixed connection-oriented and routed networks, as well as through multicast networks. Another embodiment multiplexes several flows of data into a single connection through a connection-oriented network.

摘要： Network traffic management is achieved based on automatically setting up a plurality of virtual networks (VNETs) within a single large virtual LAN. Multicast/broadcast traffic is confined to the VNET of the source, without imposing constraints on layer two addressing within the virtual LAN. VNETs are domains of users of a virtual LAN which include members of logical networks defined at layer three or higher. One method includes transferring a multi-destination packet originating from a particular node in the virtual LAN by a point-to-point path to a virtual net server. The virtual net server translates the multi-destination packet to a plurality of directed messages identifying nodes authorized to receive multi-destination packets from members of the particular VNET which originated the packet. The directed messages are then forwarded from the virtual net server to the authorized nodes. This way, multi-destination packets, such as advertisement or discovery packets, are confined to a single VNET. By confining the multi-destination packets to a single VNET, unicast packets generated within the virtual LAN are then also naturally confmed to that VNET.

摘要： A communications system interconnects local Area Networks (LAN's) across broadcast simplex channels. The LAN's are connected independently and transparently of protocols above the data link layer so that the system appears to the user at a station in one Local Area Network as one large single network. A bridge interconnects the LAN's across simplex channels. The bridge is constructed to permit more than two local area networks to be interconnected across simplex channels to the bridge and to provide communication between stations.

摘要： A controller for a bridge interconnecting local area networks operates in two modes. In a first mode the controller receives and transmits station data frames with previously appended frame check sums. In a second mode the controller responds to requests for information from stations by generating data frames from an associated memory. The controller computes and appends frame check sums and then transmits the frames and check sums to the requesting station. The controller is constructed and is effective to operate in a way which insures that all station data frames transmitted from stations to the bridge are received by the bridge without interruption or loss during all periods of operation. The controller receives all such frames at all times, including the time intervals during which circuitry in the controller must be off line and reprogrammed for changing operation between the first and second modes.

摘要： A panel platen for holding substrates such as PCBs has an automatic shimming mechanism to provide shims for panels of varying sizes and/or thicknesses. A platen includes a top surface, and a plurality of adjustable shims located below the top surface and around an edge of the platen, wherein the adjustable shims can be raised and lowered to a desired height to compensate for different sizes or thicknesses of substrates. A platen may include a top surface, a plurality of adjustable height pads located around an edge of the top surface, and a motorized control mechanism located below the top surface and configured to raise and lower the plurality of adjustable height pads. A method of automatically shimming different sized substrates on a platen includes providing a plurality of motorized shims under a top surface of the platen, and raising and lowering the motorized shims based on a size or thickness of a substrate.
