    摘要: An apparatus and method for protecting packet-switched network links, intermediate nodes, and/or end nodes from unauthorized traffic identifies authorized traffic via a signature contained in each packet that is associated with a stored cryptographic key. Packets are forwarded (or passed through) only if they contain a signature having a pre-defined correlation to the associated key. Optionally, means for controlling the protection can be provided, so that unauthorized traffic is rejected when the protection is operative but is passed when it is not. Also optionally, intermediate degrees of protection such as prioritization of authorized traffic over unauthorized traffic can be provided.

    摘要: A route switching layer is provided to end stations on a local area network (LAN) segment between the network layer protocol stack and the LAN adapter device driver. The route switching layer reads the network layer protocol header in a data frame queued for transmission. If the data frame is destined for a station on a different LAN segment, the route switching layer compares the network layer address with entries stored in a local address table. If a match occurs, the route switching layer inserts the corresponding data link layer address from the table in the data link header that is appended to the data frame. The data frame is then transmitted directly from source to destination end station by a hardware switch. If an address table match does not occur, the source station route switching layer sends a query to a route server device for the data link layer address corresponding to the network layer address of the destination end station. The route server sends a response to the source station route switching layer which then stores the destination address information in the local address table.

    摘要: Disclosed is a method of transmitting ATM cells from a sending unit to a receiving unit on an ATM link wherein each of the ATM cells includes a header portion and a data portion. In the sending unit, a header portion is identified which is common to a set of subsequent ATM cells. Then, the common header portion is transmitted from the sending unit to the receiving unit followed by all data portions of the set of subsequent ATM cells. In the receiving unit, the original set of subsequent ATM cells is generated by using the common header portion.

    摘要: A system for utilizing a transmission media such as a token ring having multiple, independent channels operating in parallel. The invention provides optimal use of multi-channel bandwidth to a plurality of interconnected workstations, file servers, and other devices. The workstations and devices attach to the token ring via dedicated lobe rings connected to concentrators on the token ring. Each concentrator contains the processors, memory, and logic necessary to coordinate the transmission and receipt of data over the token ring among the interconnected workstations and devices. The multi-channel token ring provides increased bandwidth and reliability to an existing token ring without requiring modifications to existing physical devices, interfaces, or protocols.

    摘要: A method of automatically determining an attached device type for a multi-port LAN switch, and configuring the port based on the attached device type is provided. The method comprises setting a LAN switch port to a port mode, and determining, during a first period of time, whether an attached device is attempting to insert at the LAN switch port. If the attached device is attempting to insert during this first period of time, the method continues by configuring the LAN switch port in the port mode. If the attached device is not attempting to insert during the first period of time, the method continue by setting the LAN switch port in an adapter mode, transmitting a test frame to the attached device, and then determining, during a second period of time, whether a response frame is received from the attached device. If a response frame is received during the second period of time, the method further includes configuring the LAN switch port in the adapter mode.

    摘要: A LAN switch includes port modules which receive frames from their respective LAN segments and forwards the frames simultaneously to all output ports and to a port look-up function which determines the output port to which the frames should be forwarded. If the port look-up function identifies the output port, frame transmission is halted at all ports except the identified port. By performing the forwarding function and port look-up function simultaneously, a zero latency switch is provided.
