Abstract

We propose an advanced RSA algorithm that employs iterative path relocation for shared protected elastic optical path networks. It enhances backup path sharing and reduces spectrum fragmentation. Numerical experiments verify that the proposed method can substantially reduce the total number of fibers and frequency slots needed.
