摘要： One embodiment of the present invention provides a system that facilitates transferring data between a data device and a data terminal across a network. The system initializes itself by establishing connections between the controller, multiplexer, and data device. The system operates by receiving a request at a multiplexer from a controller to transfer data from the data device to the data terminal. The multiplexer forwards this request to the data device that has the requested data. The multiplexer then receives a set of parameters from the data device, including the location of the outgoing data within the data device. The multiplexer moves the data from the data device into an outgoing data stream, thereby removing the necessity of first copying the data into the controller.

摘要： A multi-layer network element for forwarding received packets from an input port to one or more output ports. The packet is examined to look for different types of forwarding information. An associative memory is searched once for each type of information. The results from the two searches are combined to forward the packet to the appropriate one or more output ports. The packet may be examined for other information as well to make the forwarding decisions. In one embodiment, the invention examines the packet for layer 2 information as the first type and layer 3, and perhaps some layer 4, information as the second type. The results are merged to determine the most appropriate combination of layer 2 or layer 3 forwarding decisions for the packet.

A plurality of information processing modules can be removably received in the carrier, each module may have a communications port operable to connect to a communications network internal to the carrier. The modular computer system may also comprise a switch operable to connect to the internal communications network to distribute information messages between the modules and to connect to an external communications network. An information distribution module may be provided removably received in the carrier operable connect to the internal communications network to receive an information message, to perform processing on the message to determine a destination, and to forward the message toward the determined destination via the internal communications network.

摘要： A multi-layer network element for forwarding received packets from an input port to one or more output ports. The packet is examined to look for first and second forwarding information. A packet is also assigned to a class and provided with default packet forwarding information. An associative memory is searched once for each type of information. The results from the two searches are combined with the default packet forwarding information to forward the packet to the appropriate one or more output ports. In some instances, the results of the first search dominate the forwarding decision, in other, the results of the second search dominate the forwarding decision, and in still other instances, the default information dominates.

摘要： A method and apparatus are provided for implementing Quality of Service (QoS) in a network environment in which client connections are maintained for limited periods of time. According to one embodiment, packet forwarding devices of a network, such as routers, bridges, and Local Area Network (LAN) switches, are caused to forward packets associated with a client according to a particular class of service, e.g., best-efforts, premium service, associated with the user of the client by assigning a network address, e.g., an Internet Protocol (IP) address, to the client based upon the particular class of service. According to another embodiment, a method of configuring the packet forwarding devices in a network is provided. For each class of service supported, information identifying one or more ranges of network addresses that are to receive a particular measure of service associated with the class of service is communicated to the packet forwarding devices. According to yet another embodiment, a network includes one or more packet forwarding devices, a network address assignment server, and a network administration terminal. The network address assignment server is configured to receive a connection request initiated by a client, to identify a particular class of service that is accessible to a user of the client, and to assign a network address corresponding to the particular class of service to the client. The network administration terminal configures the one or more packet forwarding devices to perform packet forwarding according to the classes of service supported by identifying, for each class of service, a pool of network addresses that are to receive a particular measure of service associated with the class of service. The pools of network addresses each contain one or more ranges of network addresses from a network address space allocated to the network.

摘要： A network system dynamically controls data flow between physical links by logically combining multiple physical links into a single logical channel trunk, preferably to balance data flow carried by each link. Each link in the trunk has identical physical layer and identical media access control layer characteristics. A system server assigns a single media access control layer address to the single trunked logical channel, preferably randomly by hashing destination media access control layer addresses for the links. The system server includes, in addition to a physical layer and a network layer, a pseudo-driver software layer disposed therebetween, which pseudo-driver software layer functions as a multiplexer in a receive path and functions as a de-multiplexer in a transmit path. The resultant preferably Ethernet-compatible network system operates in full-duplex mode and distributes packets from the server to the links to preserve temporal order of data flow.
