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.

Abstract: A phased array system includes at least two traveling wave antennas arranged in parallel, and each traveling wave antenna includes at least two antenna units sequentially connected. A first end of each traveling wave antenna connects to a corresponding first radio frequency channel. The first end of each traveling wave antenna connects to a signal processing module of the phased array system by using the corresponding first radio frequency channel. A phase and/or an amplitude of a signal inputted by the signal processing module from the first end into the traveling wave antenna may be adjusted by adjusting a configuration of the first radio frequency channel.
