TL;DR: In this article, a detailed capital expenditure model developed by researchers from system vendors and network operators is introduced to evaluate multilayer (ML) metro and core network architectures based on the Internet protocol/multiprotocol label switching (IP/MPLS), MPLS-transport profile, optical transport network and WDM technology.

TL;DR: This paper presents and analyzes how disaggregation models in the wavelength division multiplexing (WDM) transport layer could replace the established aggregated model based on mono-vendor systems.

TL;DR: An algorithm is proposed that takes into account the actual physical layer performance to provision the lightpaths with actual margins, optimizing the decisions regarding the placement and transmission parameters of transponders and regenerators including their launch powers.

TL;DR: A strategic and distinctive effort is made to incorporate metro WDM topologies, traffic profiles and daily variation patterns, fault-tolerance requisites, and network operational choices, that faithfully reflect the expected 5G metro progression for a national carrier.

TL;DR: A novel and simplified cost model for designing and evaluating a Central Office Rearchitected as a Datacenter (CORD) with a special focus not only on relative costs but also on power consumption figures is introduced.
