A Novel 2-Hop Flow Approach Main Idea: A given cycle may handle all traffic transiting through the common node of any 2-hop segment intersecting the cycle structure at its end-nodes. Four Case Diagram: Basic operating principle assuming the 2-hop segment as … “virtual on-cycle span failure” for any intermediate on-cycle node failure, “virtual straddling span failure” for any intermediate off-cycle node failure. BLSR-like behavior, full on-cycle failed flow Failed flow partially on the cycle Failed flow: on-cycle nodes and straddling spans Off-cycle node failure, straddling flow
