摘要： An apparatus for controlling buffering of an arrival packet. The apparatus includes a packet buffer for temporarily storing each of one or more packets to be transmitted in association with an arrival time thereof, and a packet discard section for determining an arrival packet to be discarded or to be stored in the packet buffer, based on a discard condition defined by using a packet residence time that is calculated on the basis of one or more residence times of one or more packets staying in the packet buffer, wherein the arrival packet is defined as a packet that has newly arrived at the apparatus.

摘要： In a data transmission device and method provided with e.g. duplexed switches outputting frames in the order of input for continuing the communication without instantaneous interruptions even though one of the switches are faulted, input interfaces generate frames in which every time data is inputted, input order information indicating the input order is added to the data together with unique information of each input interface and providing the frame generated to the switches in parallel. At least one output interface sequentially stores the frames outputted from the switches for every unique information and selects a first arrived frame among the frames stored with same input order information.

摘要： In a packet relay method and device which can reduce a congestion of switching even when segment data are concentrated, segment data dividing portions respectively extract a destination address and a packet length from received packets, divide the packets into predetermined length data based on each packet length, and generates location information indicating locations in the packets respectively for the data. The segment data dividing portions add segment headers in which the location information, the destination address, and an address of its own device as a source address are set are added to each of the data, generate segment data, and provide the segment data to switches within a switch card in parallel.

摘要： The object of the present invention is accomodating local connectionless information (data that is immediately transferred without establishing a path to a receive side), such as LAN data in a local area network, by an asynchronous transfer mode (ATM) network using a connection-oriented communication system (which makes data transfers after verifying that a path to the receive side has been established), thereby performing efficient, fast routing of connectionless information. A connectionless communication system of the present invention is equipped with connectionless information cell assembly/deassembly means for bi-directional conversion between variable-length connectionless information and fixed-length connectionless cells, routing control means for analyzing a destination address of information in connectionless cells and controlling the routing of the connectionless cells; and an ATM network for connecting the connectionless information cell assembly/deassembly means and the routing control means by a permanent virtual channel serving as a fixed path and connecting the routing control means together by a virtual channel serving as a semi-fixed path, whereby connectionless information is segmented into connectionless cells and the connectionless information is exchanged within the ATM network in connectionless cell units.
摘要翻译：本发明的目的是通过异步传输模式（ATM）网络使用本地无连接信息（即，在不建立到接收侧的路径的情况下立即传送的数据），诸如局域网中的LAN数据，（在验证到接收侧的路径已经建立之后进行数据传输），从而执行无连接信息的有效，快速的路由。本发明的无连接通信系统配备有用于在可变长度无连接信息和固定长度无连接小区之间进行双向转换的无连接信息单元组合/拆卸装置，用于分析无连接小区中的信息的目的地地址的路由控制装置，以及控制无连接单元的路由; 以及用于通过用作固定路径的永久虚拟通道连接无连接信息单元组装/拆卸装置和路由控制装置并通过用作半固定路径的虚拟通道将路由控制装置连接在一起的ATM网络，由此无连接信息被分割成无连接小区，并且在无连接小区单元内的ATM网络内交换无连接信息。
