Why Unified Network Architecture?

Globalization of traffic Cloud. Big Data. Big Science. High bandwidth flows. Ultra Long Distances

Growing complexity DWDM. OXC. Routers

Metro. LH. Submarine

Cost of Disruptions Reliance on Fiber Infrastructure Significance of Survivability

Switching Network

Value of Integrated Switching WDM + Stand-alone OXC’s: 2 Platform Solution

Standalone OXC

• 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
