Increasing WAN Traffic and The Multiplier EffectUser-to-DC and DC-to-DC
930xNetwork Traffic

Data Centers
24 miles,8 millionlive streams
Less Predictable, More Dynamic
Traffic Increasing East-West
Traffic Increasing North-South

Present Mode of Operation Can Be Improved
Transport layer has historically been static, inefficiently utilized
Network layers operating in Isolation
Transport layer programmability• Dynamic transport layer can reduce overprovisioning & generate new revenues• Multi-layer optimization can reduce resources, e.g. router ports• Multi-layer provisioning and monitoring can reduce opex
Packet-Optical Transport(P-OTN)
IP/MPLS Routers

Requirements for Programmable Transport Layer
Multi-layer Switching,Simple Packet
Massively Scalable Optics
Automated, Intelligent,Programmable
The Transport Layer must be
Packet-Optical Transport(P-OTN)

• Internet/Cloud unleashes value, applications, utility
• But also layers of specialized devices
• High capex, space, power, SW upgrades, cabling, troubleshooting – not scalable
