摘要：: <p>A system for identifying preferred source nodes and preferred target nodes for nodes of a trunk within a telecommunications network. Each node is connected to an output link of the trunk. A preferred source node for a node is a source node of a restoral route to bypass the output link. A preferred target node for a node is a target node for a restoral route when that node is the source node of the restoral route. The system comprises a read restoration node topology component, a build restoral route table component, a build preferred node table component, and a download component. The read restoration node topology component that reads information describing the topology of the telecommunications network. The build restoral route table component builds a table of restoral route for a trunk of the telecommunications network. The restoral routes are identified from the information describing the topology of the network. The build preferred node table component builds a preferred source node list and a preferred target node list for each node on the trunk based on the restoral route table. The download component downloads the preferred source node lists and the preferred target node list to the nodes of the trunk.</p>
