摘要： Communication node including a transmission equipment which communicates user data with transmission equipment of an adjacent node, and a controller which communicates a message with a controller of the adjacent node and which manages the transmission equipment of its own node, wherein: a controller of the node detects existence or nonexistence of fault of a controller of the adjacent node on the basis of situation of receiving a message sent from the controller of the adjacent node; when the controller of the node detects the fault of the controller of the adjacent node, the controller of the node issues a state reference notice to a transmission equipment of its own node and checks existence or nonexistence of fault alert detection; in a case where the fault alert detection of the transmission equipment of the node does not exist, the controller of the node maintains a path state of the node.

摘要： In a network wherein a data plane for communicating user data, and a control plane for managing data forwarders are configured of different media, the path teardown of the data plane which is forwarding the data is prevented when a fault has occurred in only the control plane. When the GMPLS controller of the control plane has detected refresh timeout with respect to an adjacent node (101 in FIG. 1), it checks whether or not a transmission equipment corresponding to a faulty controller has a fault (102), and it maintains a path state (103) in a case where the fault is limited to the control plane. Thus, the exchange of refresh messages with the adjacent node is continued without cleaning up the resources of the transmission equipment (104 through 107).

摘要： In order to reduce load at a resource managing node for exclusive control of a shared resource, each node has a group of lock state registers each corresponding to one of the nodes. Before one node issues a lock request to a resource managing node, the node checks the register group to see if the resource managing node is unlocked. With the target node found to be accessible, the access requesting node sends to a broadcast message exchange circuit a broadcast request message including a lock request regarding the resource managing node. The broadcast message exchange circuit receives such broadcast request messages from access requesting nodes, and changes them serially into broadcast messages for broadcast to all nodes. Of these broadcast messages, the first message received by each node is processed by its lock control circuit so that the lock request in that message is allowed to lock the resource managing node. The lock control circuit writes the number of the access requesting node into the register corresponding to the resource managing node. The access requesting node checks the register contents to see if the lock request it issued has been successfully accepted.
