摘要： An access node run as a packet switching apparatus enables IP connection services for a plurality of access methods; e.g., relatively low-speed IP connection, high-speed 1P connection, and mobile network IP connection. By using this apparatus of the present invention, cost can be reduced and upgrading to advanced access networks and access services is easily carried out. Provision of the above access nodes implements upgrade-type network services common for diverse protocols. Each access node retains a pathfinding table to which input port, input tunnel identifier and input session identifier entries in a set are registered per session. When routing a packet, by looking up the set of these entries matching with the packet, the associated output port, output tunnel identifier, and output session identifier are obtained. After processing for the packet, appropriate for one of the plurality of access methods and network services, the node forwards the packet over the routed path.
摘要翻译：作为分组交换装置运行的接入节点能够实现多种接入方式的IP连接业务; 例如，相对低速的IP连接，高速1P连接和移动网络IP连接。通过使用本发明的装置，可以降低成本，容易地进行高级接入网和接入业务的升级。上述接入节点的配置实现了各种协议通用的升级型网络服务。每个访问节点保留路径寻找表，每个会话向其注册一个输入端口，输入隧道标识符和一组中的输入会话标识符条目。当路由数据包时，通过查找与数据包匹配的这些条目的集合，获得相关联的输出端口，输出隧道标识符和输出会话标识符。在针对分组的处理之后，适于多个接入方法和网络服务之一，节点通过路由路径转发分组。

摘要： A router apparatus 5 is provided with an ATM switch, an IP controller for performing routing control as a controller for layer 3, plural kinds of interfaces which are individually provided to plural transmission paths in which various communications are performed, and a cell multiplexing/demultiplexing unit, and manages the cell communications between respective parts on the basis of identification information. The input packet is subjected to IP processing in an interface to be converted to a cell in a common format, and the cell is serially multiplexed with a cell from another interface on a cell basis, and transmitted to the ATM switch at the cell multiplexing/demultiplexing unit. Each interface and each cell multiplexing/demultiplexing unit sets and switches the identification information for the header portion of the packet and the cell to be communicated by using a table in which the corresponding relationship of the identification information is registered.

摘要： An LAN interface unit and an ATM switch unit cooperate to perform traffic control. A QoS unit monitors circumstances of an input buffer from a multiplexer of the ATM switch by means of a system controller and when an overflow of the input buffer is expected, the LAN interface unit of the multiplexer is instructed to perform traffic control. The LAN interface unit performs traffic control such as limitation of ATM cells inputted in the ATM switch.
