Method and system for reducing packet loss in a service protection scheme

摘要

Embodiment of the present invention discloses a method for reducing packet loss in a service protection scheme, including: 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. Embodiments of the invention further provide a corresponding system. Technical solutions in embodiments of the invention, by performing 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.
