Optical Impairment-Aware WSON Control Plane for 
Cisco ONS 15454 MSTP 

Transport network solutions have undergone a tremendous technology evolution. In addition to increases in  

network bandwidth and reach, management and service provisioning have become easier. Generalized 

Multiprotocol Label Switching (GMPLS) has helped to introduce dynamic service provisioning into the transport 

network. In time-division multiplexing (TDM) networks and IP Next-Generation Networks (IP-NGNs), dynamic 

service provisioning is made possible by Automatic Switched Optical Network (ASON) and GMPLS technology for 

SONET/SDH, along with Optical Transport Network (OTN) cross-connects and IP/MPLS for routers.  

For any high-bandwidth network, dense wavelength-division multiplexing (DWDM) forms the underlying transport 

layer. ASON, GMPLS, and MPLS assume all-regenerated networks or preprovisioned wavelengths, because they 

consider all links as point-to-point, without optical awareness. DWDM has evolved from a point-to-point transport 

technology used to overcome the fiber exhaust problem to a more flexible wavelength-switching platform, with the 

evolution of multidegree reconfigurable optical add-drop multiplexers (ROADMs) with omnidirectional and colorless 

switching capabilities. The multidegree and reconfiguration capabilities translate into a full-mesh network, with a 

large number of possible optical paths. It is not feasible to validate all these paths during the planning stage, and 

real-time validation is needed while provisioning new services or assigning new paths to existing services. 

Product Overview 

The architecture of the Cisco

®

 Wavelength Switched Optical Network (WSON) Control Plane for the Cisco ONS 

15454 MSTP enhances GMPLS capabilities with awareness of wavelength properties and optical impairments, 

offering dynamic service provisioning and restoration on a flexible DWDM network. This approach provides a 

converged dynamic network architecture, as shown in Figure 1.
