Abstract

The restoration based on P-Cycle offers ring-like speed and mesh-like capacity efficiency, but the major challenge resides in finding an optimal set of P-Cycles. A new restoration method named Pre-planned restoration rail (P-Rail) is proposed, and formulates the optimized Integer Linear Programming (ILP) algorithm and the sub-cycle rerouting algorithm. P-Rail yields the harsh need of restoration time and increases the restoration probability and the reserved resource capacity efficiency, which improves the effectiveness and reliability of the fast restoration mechanisms in optical transport network of highway.
