Abstract
A ring network protection method is disclosed. When a fault occurs in a ring network, a first node selects a protection tunnel according to a fault condition of a pre-established protection tunnel. Services are switched to the selected protection tunnel. A protection switching request is sent on the selected protection tunnel and another end node is informed of the selected protection tunnel to switch the services to the selected protection tunnel.
