Abstract
This application provides a method including updating a candidate state of the node based on a candidate state of an adjacent downstream node; updating a public identifier of the target node to a public identifier of the adjacent downstream node in response to that the candidate state of the adjacent downstream node is the first candidate state and the public identifier of the target node is less than the public identifier of the adjacent downstream node; and in response to that the candidate state of the adjacent downstream node is the first candidate state and a private identifier of the target node is equal to the public identifier of the adjacent downstream node, determining that a loop exists in a dependency path corresponding to the target node.
