What drives integration
Need…. Response…
Reduce CapEx/OpEx Integrate layers – IP/MPLS/OTN/DWDMEliminate Costly InterconnectCommon Mgmt, Fabric, Line CardsOptimize High Cost Optics Utilization
Increase Service Velocity Coordination of Layers thru Control PlaneDWDM Switched End-End
Enhance Resiliency / trouble shooting
ZPL/ZTL via Proactive ProtectionLimit L0 risks with SRLGCoordinated maintenanceCP – IP/OTN protect and DWDM Restore
Reduce planning / forecasting cycles
Integrate Layers – L3 – L1 – Common FabricCP– verify circuit availability leveraging DWDM CP

Integration Example: Control Plane multi-layer interaction
• WSON = Wavelength switched optical network
• ASON = Automatically Switched optical network
• ASMN = Automatically switched MPLS-TP network
