Abstract
Embodiments of the present application provide a method for determining a forwarding path and a control device. The method includes: obtaining a first-forwarding-path computation request, where the first-forwarding-path computation request instructs to compute a first forwarding path that is from a source node to a destination node and that satisfies a first constraint; and when the control device computes at least two forwarding paths that satisfy the first constraint, obtaining, based on a mapping relationship between a path computation reference constraint and a priority, a path computation reference constraint having a highest priority, and determining, based on the path computation reference constraint having the highest priority and from the at least two forwarding paths that satisfy the first constraint, at least one forwarding path that satisfies the path computation reference constraint having the highest priority.
