Multipath provisioning (MPP) in elastic optical networks (EONs) can improve the network performance effectively. In this paper, we study the protection schemes for MPP to ensure 100% restoration against single-link failures. We design three algorithms, namely, Instant-ILP, PWCE-MPP and mPWCEMPP. The first one leverages a simple integer linear programming (ILP) model to design the optimal working-backup structure for each request instantly, while the rest two utilize protected working capacity… CONTINUE READING
