    摘要: 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.

    摘要: 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.

    摘要: 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.
