1 Unified Subsea-Terrestrial Mesh Networking the New Normal Anuj Malik, Wayne Wauford Infinera

2 Why Unified Network Architecture? Growing complexity DWDM. OXC. Routers Metro. LH. Submarine Globalization of traffic Cloud. Big Data. Big Science. High bandwidth flows. Ultra Long Distances Cost of Disruptions Reliance on Fiber Infrastructure Significance of Survivability Infinera

3 Typical Terrestrial/Subsea Network Back to Back Connections Truck Rolls to reconfigure Provisioning Across terrestrial Back to Back transponders Provisioning Across subsea Segmented Protection No end-to-end provisioning Infinera Confidential & Proprietary

4 Next Generation SLTEs New Normal Eliminates Back to Back Connections Improved Operations End to End Provisioning/Protection/Management Superior Service Availability Automated end-to-end provisioning Infinera Confidential & Proprietary

5 Key Architecture Pieces for Unified Network Integrated DWDM and OTN Switching Software Intelligence Better Resiliency Infinera Confidential & Proprietary

6 Value of Integrated Switching Without Digital Switching: Inefficient, Static Many, poorly filled wavelengths 1x10G 4x10G 3x10G 10% fill 40% fill 30% fill 4 x 10G 1 3 x 10G 1 x 10G WDM Network All-Optical Services over wavelengths Muxponder tax inefficiency Optical-only switching No digital switching & reconfiguration Patch panel & truck-roll re-grooming Infinera Confidential & Proprietary

7 Value of Integrated Switching WDM + Stand-alone OXC s: 2 Platform Solution Switching increases λ utilization 1x10G 4x10G 3x10G 10% fill 40% 80% fill fill 30% fill 4x10G 1 3x10G 1x10G $$$, complexity, space, & power Switching Network Standalone OXC OXC provides network efficiency 2 platform solution: space & power Back-back client connections Segmented provisioning/protection No end-end management/automation WDM Network All-Optical Services over wavelengths Muxponder tax inefficiency Optical-only switching No digital switching & reconfiguration Patch panel & truck-roll re-grooming Infinera Confidential & Proprietary

8 Value of Integrated Switching Collapsing Layers, Simplifying Networks 1x10G 4x10G 3x10G Efficient converged network 4x10G 3x10G 1 1x10G 4 x 10G 3 x 10G 1x 10G $$$, complexity, space, & power Switching Network WDM Network 10% fill 40% 80% fill 30% fill Converged DWDM & OTN Switching Standalone OXC All-Optical Converged OTN/WDM switching Eliminate I/C cost, extra space/power Eliminates many points of failure Automated, end-end provisioning End-to-end service protection OXC provides network efficiency 2 platform solution: space & power Back-back client connections Segmented provisioning/protection No end-end management/automation Services over wavelengths Muxponder tax inefficiency Optical-only switching No digital switching & reconfiguration Patch panel & truck-roll re-grooming Infinera Confidential & Proprietary
