Abstract
In a path determining method, a first device obtains a path health degree of a forwarding path from a source network element to a destination network element, where the path health degree is based on network element health degrees of network elements and link health degrees of links in the forwarding path, the network element health degree is based on a network element fault type and a network element fault occurrence frequency within a first monitoring periodicity, and the link health degree is based on a link fault type and a link fault occurrence frequency within a second monitoring periodicity; and determines a target forwarding path based on constraint information and the path health degree, where the constraint information includes health degree constraint information, and the health degree constraint information indicates a condition that a path health degree of the target forwarding path is to meet.
