A method, system and device for recovering services are provided, which relate to the field of communication. The method includes the following steps. Working resources of a Traffic Engineering (TE) link in a network are set to a shared MESH recovery state, and information of the shared MESH recovery state is flooded into the network, in which the information of the shared MESH recovery state is used to broadcast that the failure recovery mode of the working resources of the TE link is a band-level shared MESH recovery mode; whether the TE link fails is detected; and when detecting that the TE link fails, services on the working resources of the TE link are recovered by switching the N band-level FA LSPs on the TE link to the corresponding N band-level shared MESH recovery paths. The technical solutions reduce service recovery time and satisfy service requirements of customers while increasing bandwidth resource usage rate. |
