Modeling and Simulation of Optical Transport Networks in Telecoms

Abstract

Systematically transmitting information over an optical medium, such as fiber, is the major goal of optical transport networks (OTNs) in telecom, including network capabilities/functions, in addition to the technologies needed to support them. Aspects related to time synchronization/distribution in such network technologies are also included in their definition. The focus of this PhD thesis will be the transport and networking of digital client payloads over fiber optic cables. Although the optical transport mechanisms (OTN, Synchronous Digital Hierarchy (SDH), Ethernet over Transport (EoT), Multi-Protocol Label Switching Transport Profile (MPLS-TP)) established in the transport plane are of great importance in networking, the efforts to standardize the functionalities of OTN, EoT and MPLS-TP need to be taken into account. Aspects of control plane management and associated equipment, including Automatically Switched Optical Networks (ASONs) and Software Defined Networks (SDNs), with broad application areas, are also within the scope of this thesis.
