1. 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
