The invention discloses an Ethernet ring network-based PBB-TE protection method, which comprises the following steps of: quickly recovering communication by utilizing wrap data messages; and triggering the switching of main and backup links by utilizing the wrap data messages. The method solves the problem of expandability of the application of the PBB-TE technology on the ring network, reduces network resources occupied by the CCM messages, and simultaneously avoids momentary interruption of the communication during switching the chains.
