摘要： A data relay apparatus for data relay in a ring-type network for data including a path identifier which is transferred according to the path identifier, receives the data; stores the path identifier that is used to determine a data path in which the data is transferred in the ring-type communication network in association with a reception direction and a transmission direction of the data; compares the path identifier included in the received data and the path identifier stored by an information storing part to determine a path for receiving and transmitting the data and switches the transmission direction of the data based on a reception direction of a failure notification message notified when a communication failure occurs and whether a switching inhibition message transmitted concerning the communication failure is received; and transmits the data in the switched transmission direction.

摘要： A system that allows information of MPLS layers to be reported to PW layers by providing a function having a correlation between MPLS layers and PW layers. A transmission system uses MPLS (Multi-Protocol Label Switching) tunneling and label technology to map a communication service to MPLS, thereby providing bidirectional services on an end-to-end basis. The transmission system is a communication system comprising a means to perform label assignment control for bidirectional services; a means to transmit, after completion of assignment control, a message in which the LDP message used in assignment control is a payload and a tunnel-directed label (L2) used by bidirectional services is a header; and a means to associate, on the basis of the received LDP message used in assignment control, a service-directed label (P1) included in the LDP message with the received tunnel-directed label (L2) in the part where the message is terminated.

摘要： According to the transmission method, labels to be used at the failure occurrence are previously and individually set to links in respective directions among all nodes on the one directional link connecting between adjacent nodes basis, and when a failure occurs, a failure notifying message is sent out onto a same directional ring from a termination node of a failed block, to be sequentially transferred to each downstream node, and a label table for connecting the links in cooperative with the reception of the failure notifying message is created in each node, and also, a bypassing path is formed by turning back the rings at both end nodes of the failed block. Thus, in a ring network of label switching system, it becomes possible to easily perform the label table management and also to set a bypassing path in a short time at the failure occurrence.
摘要翻译：根据传输方法，在故障发生时使用的标签被预先单独地设置为在相邻节点之间连接的一个定向链路上的所有节点之间的各个方向上的链路，并且当发生故障时，发送故障通知消息从故障块的终止节点出发到相同的定向环上，被顺序地传送到每个下游节点，并且在每个节点中创建用于连接链路与接收到故障通知消息的标签表，并且还，通过在故障块的两个端节点处转回环来形成旁路路径。因此，在标签交换系统的环网中，能够容易地执行标签表管理，并且能够在故障发生时在短时间内设置旁路路径。
