Abstract: A method for reducing packet loss includes: performing automatic and real-time adjustment to cost values of a first route and a second route, so that the cost value of the corresponding route of the primary PW is lower than that of the corresponding route of the secondary PW. A corresponding system is also provided. Automatic and real-time adjustment to cost values of the first route and the second route, enable the cost value of the corresponding route of the primary PW to be lower than that of the corresponding route of the secondary PW, and therefore enable the downlink traffic not passing through the PW that just recovers from a failure, thereby reducing packet loss when the downlink traffic passes through the PW while the primary PW just recovers from a failure.
