摘要： A communication apparatus stores therein link information indicating a network connection status of an entire hierarchical network, collects link information indicating a network connection status in its own area in predetermined cycles, and transmits the collected link information to another area assigned a level different from a level assigned to its own area. When receiving link information from another area assigned a different level, the communication apparatus determines whether the received link information is new link information newer than link information stored in a predetermined storage unit; when it is determined that the received link information is new link-information, the communication apparatus stores the new link information into the predetermined storage unit and advertises it in its own area; by contrast, when it is determined that the received link information is not new link-information, the communication apparatus discards the received link information without storing and advertising.

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。
