Layered Structure of Optical Transport Networks
The diagram titled “The multiple layers of the OTN network” clearly illustrates how the various layers within the OTN framework work together to ensure smooth transport of different client signals, including Ethernet, Fiber Channel, MPLS/IP, and SDH/SONET. This document provides a tutorial for Optical Transport Network standards and their applications. ITU-T defines an optical transport network as a set of optical network. Each layer plays a crucial role in optimizing network performance, with the access layer focusing on user connectivity, the aggregation layer on efficient data consolidation, and the core layer on robust and high-capacity interconnectivity.
