<p>Embodiments of the present invention provide a method for adjusting a link overhead and can prevent occurrence of a micro ring phenomenon. The method comprises: determining at least one pair of to-be-processed nodes; determining a path overhead change value of each to-be-processed node, wherein the path overhead change value of the each to-be-processed node is a difference between a first path overhead and a second path overhead of the each to-be-processed node; based on the path overhead change value of the to-be-processed nodes, performing at least two times of adjustment on a link overhead of a first link, and when the first link is recovered from a fault, making a next-hop node in a first path in each pair of to-be-processed nodes migrate an optimal path to a first node to the first path earlier than a previous-hop node, or when the first link is faulty, making the previous-hop node in the first path in the each pair of to-be-processed nodes migrate the optimal path to the first node out of the first path earlier than the next-hop node.</p> |
