Protection switching method and system of the invention discloses a P2MP multicast tunnel, the method includes: between the root node and the leaf nodes of P2MP multicast are established by the main tunnel and backup tunnel; the statistics of each leaf node of the main tunnel into the interface flow, the main flow of each leaf node; switch the leaf nodes according to their main standby tunnel traffic. The invention realizes the 50ms switching of the P2MP multicast tunnel without affecting other normal branches and the random failure of the tunnel by counting the flow rate of the leaf node.
