Robust Network Design for Software-Defined IP/Optical Backbones [PDF]

open access: yesarXiv, 2019
Recently, Internet service providers (ISPs) have gained increased flexibility in how they configure their in-ground optical fiber into an IP network. This greater control has been made possible by (i) the maturation of software defined networking (SDN), and (ii) improvements in optical switching technology. Whereas traditionally, at network design time,
