    • A data transfer apparatus and a data transfer system are provided that can reduce the cost of installing communication equipment compatible with each of several dissimilar communication protocols in one exchange office and can reduce the cost of constructing the network. The data transfer apparatus includes a data reception device (110) that receives packets that comply with dissimilar communication protocols from upstream data transfer apparatuses (51, 52, and 53); a content data extraction device (120) that extracts content data included in the packets; a line selection information storage device (130) that stores the line selection information for selecting communication lines that comply with dissimilar communication protocols; a line selection device (140) that selects the communication line compatible with content data based on the line selection information; and a data transfer device (150) that transfers data to downstream data transfer apparatuses (61, 62, and 63) that are connected to the communication line that has been selected by the line selection device.

    • The purpose of the present invention is to provide a datagram transfer network that can operate stably by avoiding a state of congestion collapse by utilizing information derived from evaluating the impact of datagrams on the operation of the network. To achieve this objective, the results of evaluation is expressed as a preference value related to datagrams, and are inserted in the header in each datagram so that the datagrams are processed by an approach other than the methods based on arrival sequence of datagrams, when derived to the destination indicated in the header. In this approach, datagrams are protocol is controlled by priority order derived from the preference value which reflects traffic information obtained by a traffic monitoring equipment.
    • 本发明的目的是提供一种数据报传输网络,其可以通过利用从评估数据报对网络的操作的影响而导出的信息来避免拥塞崩溃的状态来稳定地运行。 为了实现这一目标,评估结果被表示为与数据报相关的偏好值,并被插入到每个数据报的头部中,以便在导出时基于数据报的到达序列的方法来处理数据报 到标头中指示的目的地。 在这种方法中,数据报是通过优先级顺序控制协议的,该优先顺序是反映由交通监控设备获取的交通信息的偏好值。
