The application discloses a routing protection method based on hop number dependence and partial order calculation, which fully utilizes partial order routing calculation and hop number to solve the routing protection task. Firstly, all paths are divided into atomic comparison paths and non-atomic comparison paths, all paths of source and destination nodes are divided into incomparable path sets and comparable path sets through partial order routing calculation, and path consistency forwarding is ensured by using the cumulative calculation mode of the next hop of the bifurcation node; secondly, the comparable path set is pruned through a hop number pruning strategy, an intersection point set and a pruning strategy combined with hop number; finally, a candidate path set of a Top1 path and a candidate path set of a Top2 path are obtained, and particularly, the application reduces the time complexity of processing paths through a double stack structure. In a real network topology, compared with the existing common routing protection scheme, the application improves the protection rate of the Top1 path, and can guarantee that the Top2 path has better performance.
