  • Patent number: 7787364
    Abstract: A control scheme is disclosed for controlling establishment of a standby channel route for an active channel route in a GMPLS network made up of plural transmission apparatuses. The standby channel route is formed by at least one standby channel route transmission apparatus, an ingress transmission apparatus, and an egress transmission apparatus. The control scheme involves transmitting from the ingress transmission apparatus to the standby channel route transmission apparatus a standby channel path establishing message including pre-reserve information for directing the standby channel route transmission apparatus to pre-reserve a standby channel path of the standby channel route, and setting the standby channel path to pre-reserved status within a band management table of the standby channel route transmission apparatus. The standby channel path that is set to pre-reserved status within the standby channel route transmission apparatus is externally recognized as free by the other transmission apparatuses.

  • Publication number: 20100128611
    Abstract: Upon detecting the occurrence of a fault in a path that includes the transmitting apparatus, a transmitting apparatus transmits fault information including information about the fault to an initial node in the path corresponding to the fault. Upon receipt of the fault information, a transmitting apparatus determines whether an alarm is generated by a plurality of nodes due to the fault. Having determined that the alarm is generated due to the fault, the transmitting apparatus communicates a message including alarm masking information that suppresses the alarm with a terminal node via an intermediate node included in the path. Upon receipt of the message including the alarm masking information, a transmitting apparatus performs masking control so that an alarm is not to be issued to the management device connected thereto based on the alarm masking information.
