摘要: The problem of differentiated Multi-Layer Integrated Survivability (MLIS) in IP over WDM networks is studied, which decomposed into three sub-problems: survivable strategies design (SSD), spare capacity dimensioning (SCD), and dynamic routing (DSR). A related work network survivability firstly provided, adaptive are also designed. new Shared Pool (ISP) approach for SCD then proposed, formulated by using integer-programming theory. Moreover, a novel scheme called Differentiated Algorithm (DISA) DSR developed. Simulation results show that the proposed integrated performs much better than other solutions (e.g., "highest layer recovery" "lowest schemes) terms traffic blocking ratio, resource requirement, average recovery ratio networks.
