The invention provides a shared link protection method, a node and a shared link protection system. It involves the ring network structure, and solves the problems of large data processing overhead, waste of protection resources and low rate of bandwidth reuse in the process of shared link protection. The method includes: sharing the end nodes of the link to the shared link failure in the test, get the current available at least one protection channel priority; from the at least one protection channel, select the highest priority as a business channel; the current sharing of business data switching on the link to the business the protection of transmission channel. The technical proposal provided by the invention is applicable to the ring network.
