摘要： A node in a first ring stores therein connection information about connecting nodes between a second ring and a third ring. Upon receiving a route of a working path by a signaling, the node determines any one of nodes composing the second ring as a branch node. If the working path is not terminated on an end node that the working path ends in the second ring thereon, and also if no node composing the second ring stores therein connection information between the end node and any one of the connecting nodes in the third ring that is connected to the second ring, the node compares each condition of selectable routes of a backup path between the end node and the branch node, and selects any one of the selectable routes as the backup path based on a result of comparison.

摘要： When opposed communication transmitting apparatuses A and C are connected in a physical configuration thorough a communication transmitting apparatus B, if an interface configuration changing command is input to the communication transmitting apparatus B, the interface configuration is changed in the communication transmitting apparatus B and virtual connection is achieved such that the opposed communication transmitting apparatuses A and C pass through the communication transmitting apparatus B to directly connect an interface A1 and an interface C1. In this situation, since the GMPLS operation target apparatuses are only the communication transmitting apparatus A and the communication transmitting apparatus C and the communication transmitting apparatus B is a non-target apparatus of the GMPLS operation, the GMPLS scalability problem is solved and optical signals may be transferred at higher speed.

摘要： To provide a device and a method enabling a user to judge which route a path used at the present traces without being aware of whether the now-in-use path is a working path or a recovery path. A relay device positioned at a diverging node between the working path and the recovery path, when forwarding a message (e.g., a Path message and a Resv message each containing RRO) used for route trace, judges which type of path the path employed for forwarding the data at the present is coincident with and forwards the data to the relay device disposed on the in-use path, thereby actualizing the trace of the route used for forwarding the data at the present.
摘要翻译：提供一种设备和方法，使得用户能够判断当前路径中使用的路径的路由，而不知道现在在使用的路径是工作路径还是恢复路径。当转发用于路由跟踪的消息（例如，每个包含RRO的路径消息和Resv消息）时，位于工作路径和恢复路径之间的发散节点处的中继装置判断用于转发的路径的哪种类型的路径目前的数据与设置在使用中路径上的中继装置一致并转发到数据，从而实现了目前用于转发数据的路由的跟踪。
