    Abstract: A fiberoptic network with an optical supervisory channel in each of the optical fibers interconnecting the nodes of the network is described. Together with IP routers (10A-14A), the optical supervisory channels form a control network over which signaling and control signals are exchanged by which provisioning and restoration operations are performed at each node (10-14). To restore connections between the nodes upon a failure of the network, the control network helps to maintain at each node a synchronized database of network connections between the nodes, send messages to other nodes to initiate restoration operations by a node noticing the failure; and recalculate network connections around the failure by each node from a synchronized database at the node.

    Abstract translation: 描述了在互连网络节点的每条光纤中具有光监控信道的光纤网络。 与IP路由器(10A-14A)一起,光监控信道形成控制网络,通过该控制网络交换信令和控制信号,通过该网络在每个节点(10-14)执行供应和恢复操作。 为了在网络故障时恢复节点之间的连接,控制网络有助于在每个节点处维护节点之间的网络连接的同步数据库,将消息发送到其他节点以由发现故障的节点发起恢复操作; 并从节点上的同步数据库中重新计算每个节点出现故障时的网络连接。
