Performance of routing and spectrum slot allocation model for multipath provisioning in elastic optical networks

摘要

Multipath provisioning (MPP) uses multiple disjoint paths for data transmission to tolerate network failures. This paper evaluates the performance of routing and spectrum slot allocation model for the MPP in elastic optical networks. We present the optimization model for routing and spectrum slot allocation for the MPP. Numerical results show that the required spectrum resources can be reduced by considering the routing of link-disjoint paths.
