    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.

    摘要翻译： 当相对的通信发送装置A和C通过通信发送装置B的物理配置连接时，如果向通信发送装置B输入了接口配置改变命令，则在通信发送装置B和虚拟连接中改变接口配置 使得相对的通信发送装置A和C通过通信发送装置B直接连接接口A1和接口C1。 在这种情况下，由于GMPLS操作对象装置仅是通信发送装置A，通信发送装置C和通信发送装置B是GMPLS操作的非目标装置，所以解决了GMPLS可伸缩性问题，光信号可能 以更高的速度转移。

    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： The present invention relates to a communication path calculation method and module. More particularly, the present invention provides a communication path calculation method and module that are implemented or incorporated in a transmission apparatus including a ROADM or the like which performs WDM communication, advertises information on a wavelength which can be added or dropped, as information on a link, and uses the information to autonomously calculate a communication path. Optical transmission equipment that is accommodated in a WDM network over which a wavelength-division multiplexed signal is transferred includes a reconfigurable OADM module. For calculation of a communication path, the OADM module creates a link table listing clients of the own equipment and connected WDMs, and advertises the link table to the other pieces of equipment accommodated by the network as pieces of information on restrictions to be imposed on routing from the own equipment. The other pieces of equipment each receive and store the advertised pieces of information on restrictions to be imposed on routing, and use the pieces of information as pieces of information on restrictions to be imposed on a calculation to calculate a communication path from the own equipment.
