    Abstract: PROBLEM TO BE SOLVED: To provide technology for more speedily performing optimal QoS control corresponding to an occurring fault. SOLUTION: Node arranging order extraction units 13b, 23b of token controllers 13, 23 extract addresses of nodes stored in a token packet and send them to a control unit 31. The control unit 31 analyzes the order of arranging the addresses and detects a change in network configuration caused by occurrence of a fault. A QoS table selection unit 42 uses the result to select a QoS table to be used for QoS control out of QoS tables stored in a QoS table unit 43. A QoS table reference unit 44 performs QoS control using the selected QoS table. COPYRIGHT: (C)2006,JPO&NCIPI

    Abstract: ラベルスイッチングを利用したリング・ネットワーク内のネイバー・ラベルスイッチングされたルータ（ＬＳＲ）(４３０〜４３８)間でワーキングラベルスイッチングされたパス（ＬＳＰ）（４２６）が、ワーキングＬＳＰのネイバーＬＳＲを、ワーキングＬＳＰと反対の方向において接続するＬＳＰによって保護される。 ワーキングＬＳＰに故障が生じた場合には、パケットが、保護ＬＳＰ（４２８）へスイッチングされる。 スイッチングされたパケットは、パケットがワーキングＬＳＰをトラバースした場合に到達するであろうネイバーＬＳＲに達するまで、保護ＬＳＰのトラバースを続ける。 保護ＬＳＰ上のホップの数と合わせることにより、あたかもワーキングＬＳＰをトラバースしたかのようにパケットのＴＴＬ値が保護ＬＳＰをトラバースした後の値と同一になるよう、保護ＬＳＰをトラバースしたパケットの存続時間（ＴＴＬ）値が調整される。 保護ＬＳＰをトラバースした後に、パケットを再びワーキングＬＳＰへスイッチングするか、又はネクストホップＬＳＰへスイッチングすることができる。

    Abstract: A data communication system, in which, even when communication between a child station and a parent station is broken by the child station not receiving polling from the parent station caused by a disconnection, data from child stations following the child station whose communication was broken can be collected. In a data communication system, plural stations having a pair of two-directional external interfaces (15,16) are connected in series, and a parent station collects data from each of the child stations by polling. When one of the child stations has not received the polling for a predetermined period, that child station stays as a child station by using a first external interface (15), a first transmitter & receiver section (10), and a child-station processing section (13), and also works as a second parent station that collects data from following child stations by applying the polling to following child stations, by using a second external interface (16), a second transmitter and receiver section (11), and a parent-station processing section (14).
