3 Market Forces By 2016 Traffic Growth 4X volume growth 110 Exabytes per month 90%+ will be video Device Proliferation 1.4 mobile devices per capita 3 billion IPv6-ready mobile devices 12 billion IP video-capable devices Source: Cisco VNI Forecast 2012 and IBSG Emergence of Cloud $43 billion cloud services revenues Midmarket firms more likely to migrate to the cloud Cisco Confidential 3

4 The Challenge Seek new sources of Revenue Exponential Traffic Growth Declining Revenue per bit Reduce Cost via: Incremental changes: - CAPEX reduction - OPEX reduction - Improved Utilization Architectural changes: - Convergence of layers, products Cisco Confidential 4

5 Technology evolution trends Contentionless Add/Drop Touchless ROADM Network flexibility Reduce Opex and Capex Superchannel f [GHz] Spectral Efficiency More Tbps X Link SW Defined modulation scheme 100 Gbps 100 Gbps 400 Gbps 1 Tbps 1 Tbps 100 Gbps Flex-Spectrum Convergent Packet Optical Reduce Opex and Capex Integrated DWDM Convergent Transport GMPLS Control Plane Cisco Confidential 5

6 Innovations enabling next generation IP+Optical End-to-End Automation / Orchestration Silicon No Trade-Off: Both Performance + Intelligence High Bandwidth for Video vs. High Transaction Rate for SDN Custom NPUs & Fabrics Coherent Optical DSPs Silicon Photonics (SiP) Systems Common Technology Foundation for CapEx & OpEx Savings Converged IP + Optical Unified Access Investments Integrated DWDM Multi-layer Restoration Touchless ROADM Software Applications and Services Move into the Cloud Virtualization for Scale SDN for Control and Efficiency Virtual OS Virtual Network Function Open Interface Cisco Confidential 6

7 TouchLess ROADM Complete Control in Software, No Physical Intervention Required Omni-Directional ROADM ports are not direction specific (re-route does not require fiber move) Flex Spectrum Ability to provision the amount of spectrum allocated to wavelength(s) allowing for 400G and 1T channels. Colorless ROADM ports are not frequency specific (re-tuned laser does not require fiber move) Contention-less - Same frequency can be added/dropped from multiple ports on same device. Foundation for Multi-Layer Network Programmability Cisco Confidential 7
