    • An end equipment (including a terminal equipment and a router) executes a destination address resolution of a data packet. In a network layer, when a packet transmitter detects that a direct route of an input packet is not registered in a routing table a path manager transmits an inquiry packet, demands a preparation of a point-to-point logical interface of the direct route based on a data link layer address of the destination included in the received response packet, and registers the prepared logical interface in the routing table.
    • 终端设备(包括终端设备和路由器)执行数据包的目的地地址解析。 在网络层中,当分组发送器检测到输入分组的直接路由未被登记在路由表中时,路径管理器发送查询分组,需要准备基于直接路由的点对点逻辑接口 在接收到的响应分组中包括的目的地的数据链路层地址上,并将准备的逻辑接口注册在路由表中。

    • In a relay device or the like in which a speed changes from a high speed to a low speed, a packet residence (packet transfer wait) occurs when a packet string in which packet intervals are shortened arrives. When a packet discard occurs before passing through the relay device or the like, a packet interval having been lengthened by the packet discard is shortened by the relay device or the like for transferring packets. When a packet discard occurs after passing through the relay device or the like, a packet interval having been lengthened by the packet discard remains unshortened for transferring packets. Therefore, by observing at terminals the packet discard and the packet interval on the occasion of the packet discard, whether the packet discard has occurred in the high speed section or the low speed section is specified.
    • 在速度从高速变化到低速的中继装置等中,当分组间隔被缩短的分组串到达时,发生分组驻留(分组传送等待)。 当在通过中继装置等之前发生分组丢弃时,由分组丢弃延长的分组间隔由传送分组的中继装置等缩短。 当在通过中继装置等之后发生分组丢弃时,已经被分组丢弃延长的分组间隔保持不被用于传送分组。 因此,通过在终端观察分组丢弃和分组丢弃时的分组间隔,是否指定了在高速部分或低速部分中发生了分组丢弃。

    • A data transfer system having a transfer discrimination circuit for discriminating the type of data transfer between an input/output channel device and I/O devices for a computer includes a transfer discrimination circuit. This circuit includes a edge detection unit operating in response to a tag signal supplied to the edge detection unit for detecting the trailing edge of the tag signal after a leading edge of the tag signal has passed. The edge detection unit having a leading edge detector, a trailing edge detector, a storage element, and logic gate circuits. A timing unit is included operating in response to the output of the edge detection unit for counting a predetermined time, along with a discrimination storage unit operating in response to the output of the timing unit for delivering an output indicating an interlock data transfer or an output indicating a data streaming feature data transfer.
