TL;DR: In this paper, a realistic cost model for Internet protocol/multiprotocol label switching (IP/MPLS), carrier-grade Ethernet, synchronous digital hierarchy/optical transport network (SDH/OTN), and WDM equipment from which overall capital expenditures can consistently be derived is contributed and discussed.

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: In this paper, an impairment aware network planning and operation tool (NPOT) is proposed to consider the impact of physical layer impairments in the planning of all-optical (and translucent) networks.

TL;DR: This paper surveys existing standardization efforts for the orchestration - automation, coordination, and management - of complex set of network and function resources (both physical and virtual), and highlights the various enabling technologies, strengths and weaknesses, adoption challenges for operators, and areas where further research is required.

TL;DR: This work considers a pragmatic multi-layer capacity planning approach for an IP over optical network, which builds on existing planning practices and compute the savings achieved on two real-world core network models.
