Summary:
The path-segment-protecting p-cycle (or "flow p-cycle") contributes more saving on spare capacity than conventional link-protecting p-cycle. However, this technique fundamentally requires signaling at all nodes on the restoration paths. This paper presents a new approach on routing the light-paths of node pairs in order to boost the amount of traffic traversing straddling segments in opposite directions so that both end nodes of each segment can detect any link failure on the segment and perform protection switching around a p-cycle.
