Overview:

The advent of Reconfigurable Optical Add/Drop Multiplexer (ROADM) technology and mesh optical networks challenges the operating model for transport service providers, with SONET/SDH moving to the edge and even being replaced by Layer 2 and Layer 3 traffic. Traditional point-to-point Wavelength-Division Multiplexing (WDM) becomes complex all-optical networking, eliminating the need for large Digital Cross-Connect (DXC) switch points. The superior optical intelligence brought to the field by the Cisco ONS 15454 MultiService Transport Platform (MSTP) reverses the whole paradigm, making the all-optical network easier to operate than standard traditional SONET/SDH OEO-based technology.
