<p>The invention discloses a rapid switching method for source route ring network protection, which includes that: when a fault occurs, fault section nodes or nodes adjacent to a fault node send a forward fault indication information (FDI) message to a network processor of a host end of the service passing through the fault section or the fault node; when receiving the FDI message, the network processor of the host end of the service judges whether the work tunnel of the service is valid or not; if the work tunnel is valid, the work tunnel is set to be invalid and the service is switched to a protection tunnel. The invention also provides the corresponding apparatus and system. The rapid switching method, apparatus and system for source route ring network protection realize rapid service switching, and meet the telecommunication-grade protection and switching requirement of 50ms, when the service quantity on the ring network is large.</p> |
