摘要: A resilient virtual Ethernet ring has nodes interconnected by working and protection paths. If a span fails, the two immediately on either side of failure are cross-connected to fold ring. Working-path traffic is onto path at first then back second so that always ingresses egresses from path. originating node, upon determining transmitted packets being looped due fault primary path, adapted switch transmission data secondary
